132 Revieics — Vogdes' Palceozoic Crustacea. 



It is difficult for one accustomed to the literature of geology and 

 palgeontology to judge how far the present volume will meet the 

 popular demand ; but we are inclined to think that in some cases 

 the use of imperfectly defined technical terms and expressions will 

 present difiSculties to the general reader. The occasional indis- 

 criminate use of synonymous terms (e.g. Cai'boniferous Limestone 

 and Mountain Limestone) without explanation also seems unfortunate ; 

 and it would be well to attend to these points in a subsequent 

 edition. On the other hand, for a compilation extending over so 

 wide a field the work before us is remarkably free from errors, and 

 all the mistakes worthy of note seem to be confined to palaeontological 

 and zoological subjects. Brachiopods and Polyzoa are very far 

 from being Mollusca, as the author regards them ; and the origin of 

 the name " Foraminifera " is inaccurately stated on p. 98. The 

 Devonian " dicotyledon " (p. 86) admits of a more reasonable inter- 

 pretation than that originally suggested by Sir William Dawson ; 

 and the Carboniferous fruit " migonocarpon " ought to be " trigono- 

 carpon." Several Brachiopods are mentioned on p. 96 as if they 

 were Corals ; and the first appearance of " Sharks," as generally 

 understood, is not in the Jurassic (p. 204), but in the Upper Silurian. 

 European Cretaceous Mosasaurs are more numerous than the author 

 supposes (p. 235) ; and the Eocene Snake, Falceophis, is far from 

 being a Boa-constrictor (p. 242). There are also several misprints, 

 such as Myperodopedon for Hyperodapedon, Notosaurus for JVothosaurus, 

 SimoUophis for Cimoliophis, and Unitatherium for Uintatherium.. 

 These, however, are small matters, and we only call attention to 

 them in view of a second edition, which ought soon to be required. 

 As a reliable and entertaining introduction to the subject of which it 

 treats, the work is a valuable addition to popular scientific literature. 



V. — A Bibliography of Paleozoic Crustacea from 1698 to 



1889, INCLUDING A LiST OF NoRTH AMERICAN SpECIES AND A 



Systematic Arrangement of Genera. By A. W. Vogdes. 8vo. 

 pp. 177. Washington (U. S. Geol. Survey, Bull. No. 63, 1890). 



ME. YOGDES' carefully compiled Bibliography and Catalogues 

 of Palaeozoic Crustacea are doubly welcome, when we 

 remember the extraordinary carelessness of compilation and abund- 

 ance of misprints in some recent publications of a similar nature 

 which have reached us from America. Mr. Vogdes not only shows 

 an intimate knowledge of his subject, but also his perfect competence 

 to refer to a book accurately and fully. The whole work, indeed, 

 bears evidence of a careful and painstaking endeavour to produce 

 the best results possible, instead of a hasty scramble through such 

 books as are to be found in the library of a minor town, and whole- 

 sale misquotations from others which the compiler has never seen 

 and does not trouble to find. 



There are very few misprints, and in reading his proofs Mr. 

 Vogdes has had the assistance of Prof. U. P. James. The references 

 are full ; there is no irritating series of initial letters used in 

 quotation : thus no doubt can be entertained as to the work 

 referred to.
