Observations on the evolution of caves., 1964, Cavaille Albert
In this note, which results from a paper published in France, the author defines the "karst system" formed by several successive levels, at the heart of a limestone mass: joints of surface feeding, vertical chimneys, galleries which are alternatively dry and full of water according to the season, a network of continually drowned clefts. He then studies modifications in this system resulting from internal causes, corrosion, filling and sedimentation, concretion. Then he shows how this evolution of the karst system may be modified by general conditions: geology, tectonics, geography with the losses, resurgences and the role of surface formations. The deepening of the river level may create a structure of differing levels in the various karst system, but their positioning is always slower than the streams erosion and it comes about later. In any case, the caves in a dried karst system undergo an evolution on their own. Finally, the author gives the definition of the terms used to explain the evolution in the karst system: "embryonic galleries" in the network of clefts, "young galleries" in the zone which is alternately wet and dry, "mature galleries" where the concretion and the erosion are balanced, "old galleries" where the concretion is becoming more and more important, "dead galleries" where the cave is completely filled by the deposits and concretions. This classification will easily replace the inexact terms of "active galleries" and "fossilized galleries" which are too vague and lead to confusion.

Contribution to the study of certain Lithobiidae (Chilopoda) of Romanian caves., 1965, Negrea Stefan
This paper comprises the ecological and zoogeographical data of 21 systematic units of Lithobiidae coming from 100 Romanian caves (Transylvania, Banat, Oltenie and Dobroudja). Initially the author describes in a summarising way the provenance of the studied material, after which he exposes fro every species the results of observations carried out by several authors and by himself. Finally he formulates the conclusions concerning ecology and biogeography resulting from his observations. These data are summarised in a synoptic table in which three species can be considered troglobionts, two of which are blind; these are Harpolithobius oltenicus Negrea; Lithobius decapolitus Matic, Negrea et Prunescu; Lithobius daeicus Matic; The other 18 species found are 5 troglophiles, 12 sub-troglophiles and 1 trogloxene.

The Crustaceans of the reservoir of the Fontaine des Suisses at Dijon., 1966, Dussart Bernard, Graf Franois, Husson Roger
Inventory of the Crustaceans collected in the basin of the Fonatine des Suisses at Dijon. The Copepoda are represented by 5 species: Macrocyclops albidits, Eucyclops serrulatus in two slightly different forms, Eucyclops serrulatus var. mihi, Acanthocyclops venustus, Acanthocyclops vernalis and Acanthocyclops robustus. The coexistence of these two last forms in this very tiny environment makes it probable that we have here to do with two distinct species. A determination key is given for the Genus Acanthocyclops. Amphipoda are represented by Niphargus virei and especially Niphargus kochianus kochianus of which more than 100 samples have been collected. Of this last small species some considerations regarding geography, the laying of eggs, sexual dimorphism and closely related species are also given.

Biogeography of Troglobites, 1971, Barr Thomas C. , Holsinger John R.

Biogeography of Troglobites. Reply, 1971, Poulson, Thomas L. White, William B.

A new species of the subterranean Amphipod genus Allocrangonyx (Gammaridae), with a redescription of the genus and the remarks on its zoogeography., 1971, Holsinger John R.
The systematics of the North American, subterranean amphipod genus Allocrangonyx are revised and two species are recognized; A. pellucidus (Mackin) and A. hubrichti, new species. Allocrangonyx is critically compared with the European genus Niphargus and several endemic North American genera of the Crangonyx group. Because of its unique morphological position, Allocrangonyx is removed from the Crangonyx group and placed in the newly designated AlIocrangonyx group. Some factors believed to have influenced speciation within the genus are discussed in some detail.

Notes on the distribution of Trichoniscidae in Sardinia (Crustacea, Isopoda, Oniscoidea)., 1973, Argano Roberto, Rampini Mauro
The study of the biogeography of the eight species of Isopoda Trichoniscidae from Sardegna brings to consider the faunistic relationships happened in the past between the island and the Pyrenees. Two of the species are eutroglophilous and rather widespread; the other six are troglobic and endemic to Sardinia. Five of the latter show strong affinity to Pyrenees forms. A detailed description is given of the distribution of the various species. This distribution makes possible some observations on the history of the fauna of the island.

The colonisation of some caver in the Jura by Niphadobota alpine Bezzi (Dipt. Tipulidae)., 1973, Turquin M. J.
Three new localities of Niphadobota (=Chionea) alpina in the French southern Jura allow the author to state that this insect's climatic requirements explain the biogeography of the species; the origin of the colonization of caves by this dipteran is considered.

Cavernicolous Pseudoscorpions from Macedonia., 1974, Curcic Bozidar P. M.
A cavernicolous pseudoscorpion of the genus Neobisium Chamberlin 1930 is living in Kalina Dupka cave in the Bistra Highland of western Macedonia. This pseudoscorpion clearly differs from the other members of the subgenus Blothrus Schiodte 1849, and belongs to the new species N. (B.) princeps, the principal features of which are described in this study. The nearest relatives of this species are N. (B.} spelaeum (Schiodte) 1849, and N. (B.) stygium Beier 1931, both from Slovenian and Croatian caves. From chelal dentition N. (B.) princeps may be considered as the most primitive element of the princeps-stygium-spelaeum series. This new species is in a subterranean mode of life of extreme specialization. Relating to biogeography, it belongs to the endemic pseudoscorpion fauna in Macedonia. After finding pseudoscorpions in Zmejovica cave (Porece mountainous area), we confirmed the presence of the species N. (E.) karamani (Hadli) 1929 in west Macedonia. Morphologic analysis of male specimens from that new locality enabled us to complete description of this species previously based on a single female specimen. The comparison of Hadzis species with N. (E.) remyi Beier 1939 from west Serbian caves, with N. (E.) brevipes (Frivaldsky) 1866 and N. (E.) leruthi Beier 1931 from Turda and Bihar caves in southern Carpathians, leads to the conclusion that these pseudoscorpions belong to a closely related species group. Judging by actual distribution of these species, the possibility exists that a wide area in the ancient Balkanic dry land had been populated by the initial form of that series. As for its preferences for habitat N. (E.) karamani is an exclusive inhabitant of subterranean environment. Relating to biogeography, it may be considered as a relic of Mediterranean Tertiary fauna and its endemic differentiation as developed under the conditions of the evolution of karst relief in southern countries of the Balkan Peninsula. In conclusion, from actual knowledge and the results of this study caves in Macedonia are inhabited by three endemic species of pseudoscorpions of genus Neobisium (Blothrus), namely: N.(B.) ohridanum Hadzi 1940,N. (B.) karamani (Hadzi) 1929, and N. (B.) princeps Curcic 1974. Judging by known blothroid pseudoscorpions, it is possible Macedonia represents one of the centres of origin and genesis for autochthonous and residual fauna of the Tertiary age.

Bogidiella martini, a new hypogean Amphipod from the island of Saint-Martin (West Indies) and the zoogeography of the Bogidiellidae., 1978, Stock Jan H.
Both sexes of a new species of Bogidiella, B. martini, are described. The new species, with a very pronounced sexual dimorphism, has been discovered in two wells in the island of St.-Martin (French part), one of the Lesser Antilles. Another member of Bogidiella has been recorded from the island of Curaao, but the specimens were damaged too much to allow proper description. The Bogidiellidae (5 genera, 26 named species, and several unnamed species) are present in the sea as well as in inland waters. The family has a wide distribution, exceeding the boundaries of the former Tethys Sea. Probably, they represent a very old stock that had acquired already a great part of its present-day distribution before the fragmentation of the primordial continent of Pangaea during the Mesozoic.
