PUBLICATIONS RECEIVED. 



Catalogue of the Marine Invertebrates of Eastern 

 Canada. By J. F. White ayes, Geol. Survey of Canada, 1901. — 

 This is a Tery useful catalogue, and gives for the first time a concise 

 record of our present knowledge of the Marine Invertebrates of East- 

 ern Canada. The work contains 271 pages, of which 98 are devoted 

 to the mollusca, 100 species of Pelecypoda, 5 Scaphopoda, 166 Gas- 

 teropoda (including 8 PoJyplacophora), and 13 Cephalopoda are listed, 

 with ample notes on their geographical and geological distribution 

 and bathymetrical range. 



Guide to the Geology and Paleontology of Niagara 

 Falls and Vicinity. By A. W. Grabau (Bull. Buffalo Soc. 

 Nat. Sci., VII., No. 1, 1901). The Buffalo Society of Natural 

 Science has appropriately signalized the Exposition year by issuing 

 a volume bearing the above title, containing a full and readable 

 account of the local geology and paleontology. On account of its 

 situation, the geology of Niagara is of course of far greater than local 

 interest, since the intensely interesting and complex history of the 

 Great Lakes is involved, so that the mass of data presented deals 

 with subjects of wide interest. It is suitably illustrated with excel- 

 lent maps and views. The paleontological part consists of an un- 

 technical account of the fossils of the region, properly illustrated by 

 good figures. 



Chapter V., by Miss Elizabeth J. Letson, describes the post- 

 pliocene fossils of the Niagara River gravels, and dealing with species 

 still existing has special interest for conchologists. Some 17 species 

 of Gastropoda and 14 Pelecypoda are discussed and illustrated. 

 Among the more notable species may be mentioned the carimate 

 form of Goniobasis livescens var. niagarensis, which reproduces the 

 contour of Ancidosa carimata ; Amnicola letsoni Walker, an appar- 

 ently extinct species ; some peculiar forms of Limncea desidiosa and 

 catascopium, and a series of Unionidce, very interesting to the student 

 of geographic distribution : — Lampsilis rectus, el/ipsiformis, Uniogib- 

 bosus, Quadrida solida and coccinea — forms speaking clearly of a 

 former connection between the Great Lakes and Mississippi drain- 

 ages. All of the species are illustrated with original figures. The 

 work is well done, and cannot but prove useful for many years to 

 come.
