CURRENT LITERATURE. 87 



The mollusca detailed in pt. i. from the former deposits, are freshwater, with 

 four terrestrial examples — undetermined species of Limax, Helix, and Succinea, 

 and Cyclostonia jagici. Altogether the list shows no species, of which a very 

 large number are described as new. 



The occurrence amongst them of the genus Caspia, established by Dybow.ski 

 for species now living in the Caspian Sea, and of forms (Bagiivia n.g. ) closely 

 approaching the Liobaikalia of Lake Baikal, is perhaps the most interesting fact, 

 since it points to the probability of the Markusevec deposits having been formed 

 under conditions similar to those now obtaining in the two inland salt-waters 

 named. 



Dr. Brusina is, however, in error when he gives 1891 as the date of 

 foundation Caspia, since the first part of volume x. of the " Malakozoologische 

 Blatter" was issued in 1887, and the genus is duly noted in the "Zoological 

 Record " for that year. 



Incidentally it is pointed out under Cyclostoma that if Hanley's statement be 

 correct, the recent C. elegans, Mull., is identical with Tuabo reflexus, L. So that 

 the strict prioritarian will, we suppose, be hastening to conceal this well-known 

 species under the designation of Pomatias reflexus ! 



Out of the twenty-two marine forms cited in the second list, only three have at 

 present been determined, so that much cannot now be said concerning them. 



The third list, or Appendix, enumerates twenty species of Congeria and seven 

 of Dreissensia, recent and fossil, with their distribution in the regions to the south 

 and east of Agram. It includes eleven new species, some of which appear to have 

 been figured in certain still-unpublished plates that are to illustrate an extended 

 work on the fossil molluscan fauna of" Dalmatia, Croatia, Slavonia and the 

 adjoining Slav territories. — (BV). 2 



Systematic List of the Frederick E. Edwards' Collection of British 

 Oligocene and Eocene Mollusca in the British Museum (Natural 

 History). By Richard Bullen Newton, F.G.S., London : i89r. (Pp. 365). 



So little attention has been devoted by malacologists in this country to Fossil 

 Conchology, the subject has fallen almost entirely into the hands of a few 

 palaeontologists. The list before us is therefore one which will be welcomed by 

 all as coming from a competent conchologist who has had the guidance and 

 assistance of many well-known authorities. 



Besides the Edwards' Collection, there are comprised in this list the types of 

 the Eocene Mollusca in the Bowerbank, Brander, Brown, Dixon, Gardner, 

 Mantell, Prestwich, Shrubsole, William .Smith, Sowerby, Wetherell and Wise 

 collections ; in all enumerating 255 genera and 1229 species, of which 428 are 

 Lamellibranchs ; 7S6, Gasteropods ; and 15, Cephalopods. 



It is impossible in the space at disposal to even enumerate, much less to 

 discuss, the many important changes in classification and nomenclature that are 

 here introduced. A few of the more important are : — 



Axincea, Poli, 1795 has priority of Pecluncuhts, Lam., 1799. 



Artica, Schum., 18 17 ,, ,, ,, Cyprina, Lam., 18 1 8. 



Meretrix, Lam., 1799 ,, ,, ,, Cytherea, Lam., 1806. 



Ci/spidaria, G.N.'Na.rdo, 1840 ,, ,, ,, Neara, Gray, 1834. 



Thovana, Gray, 1847 ,, ,, ,, Dactylina, Gray, 1847. 



Seraphs, Montfort, 1810 ,, ,, ,, Terebellum, Lam., 1799. 



Lampusia, Schum., 1817 ,, ,, ,, Triton, Montfort. 



Trip/ex, Humphrey, 1797 ,, ,, ,, Pteronotus, Swainson,i840. 



Sycum, Bayle, 1880 ,, ,, ,, Leiostonia, Swainson. 



Batillaria, W.H.Benson, 1 S42 ,, ,, ,, Lampania, Gray (1840), 1847. 



Paludestrina, d'Orbigny ,, ,, „ Hydrobia, Hartmann, 1821. 



Generally speaking we approve of most of the changes ; there are, however, several 

 notable errors. A practice we have often condemned as childish, and 

 unscientific, is that of naming genera, species, &c. , after relations, friends, &c, 

 or places, and we regret to find that Mr. Newton makes no exception to the bad 

 example set by the British Museum authorities as regards this point. Where a 

 new name has been introduced, it would have been useful to indicate that of the 

 old genera or family, e.g., Lampiesidte, R. B. Newton (= TritonidiE, Montfort).
