274 Bibliographical Notices. 



Journal of Malacozoology, edited by K. Th. Menke. Vols. i. and ii. 

 1844-45, Hanover. Vol.iii. edited by Menke and Pfeiffer, Jan. 

 -June 1846. 



The ' Zeitschrift fiir Malakozoologie ' has been founded by Dr. 

 Menke for publishing original treatises on single families, genera or 

 species of living or fossil shells, descriptions of new species, notices 

 respecting the geographical distribution of mollusca, critical analyses 

 of new malacological works, biographical and necrological notices, 

 &c. 



The third volume begins (Jan. 1846) with a review of the geo- 

 graphical distribution of the family of Helicea, continued in the 

 numbers for May and June, by Dr. Pfeiffer. — Dr. Jonas publishes 

 his views on the genus Proserpina, Guild., to which he refers his 

 Helicina linguifera, and descriptions of some new land- shells from 

 Guinea, and marine shells from Singapore and the Red Sea. — Dr. 

 Philippi describes new species of Corbula, Tellina, Diplodonta, Lu- 

 cina, Patella, Acmcea, Siphonaria, Trochus, Buccinum, Terebra, Co- 

 lumbella and Dentalium, most of which are from Mazatlan. — Dr. 

 Dunker continues his descriptions of shells collected by Dr. Tarns 

 on the west coast of Africa, from Benguela and Zoanda. — Dr. Pfeiffer 

 gives a critical review of the genus Cyclostoma, enumerating the 

 species figured in Sowerby's ' Thesaurus,' with remarks on the fre- 

 quent priority of the names published by Grateloup, Anton, Jay, 

 Lea, &c. He describes as hitherto unpublished species : C. stenom- 

 phalum, P., Ottonis, P., limbiferum, Mke, Largillierti, P., costatum, 

 Mke, Gruneri, P., plicatulum, P., alutaceum, Mke, dubium, P., 

 hieroglyphicum (Hel.), Fer. Some other species, C. lima, Bronni, 

 Binneyanum, Adams, were already described in the ' Proceedings of 

 the Boston Society, 1845,' and C. strangulatum, probably by Benson. 

 — Dr. Jonas has examined some species figured in the ' Description de 

 l'Egypte,' and describes them together with some other new shells 

 from the same locality. — Dr. Menke gives some short necrological 

 notices. 



Indicis Generum Malacozoorum Primordia. By A. N. Herrmannsen. 

 Fasc. I. 1846. 



Since the date of the Linnaean nomenclature, an immense number 

 of creatures formerly unknown have been discovered ; and, conse- 

 quently, the quantity of names and systematical designations in every 

 part of natural science has increased in an almost overwhelming man- 

 ner. Comparatively few authors have regarded the justice due to those 

 who have preceded them in their labours; many of them have imposed 

 and changed names, without knowing whether the objects were al- 

 ready named and described or not. From this and other causes there 

 exists in every branch of zoology such a quantity of synonyms of ge- 

 nera and families, that with regard to some genera it is nearly impos- 

 sible to ascertain which name was first used, and in what sense it 

 was employed by different writers. For this purpose our author has 

 elaborated an alphabetical index of all systematical names occurring
