Notes upon a collection of shells from Borneo with de. 

 SCRIPTIONS OF New Species, by T. H. Aldrich. (From Journ. 

 Cin. Soc, Nat, Hist.) Paludomus lacunoides, Trochomorpha Kusana 

 (this is certainly a Sitala), Alyaeus broti Aldrich, and ClauslUa 

 dohertyi Boettger are described as new. A well executed plate ac- 

 companies the text. — P. 



Notes on Queensland land shells, and Notes on the 

 Helicid.e, by C. Hedley. (From Proc. Roy. Soc. Queensl., 1889.) 

 In these papers the genitalia, dentition and jaws of Helix blomfieldi, 

 fra.seri, rainbirdi and paclujsiyla are described and figured. It is 

 highly gratifying to receive these valuable additions to our scant 

 knowledge of the soft parts of Australian land shells. — P. 



Catalogue of the shell-bearing Mollusca of Rhode 

 Island, by H. F. Carpenter. This catalogue is a' supplement to 

 the series of papers published in Random ^otes and the Concholo- 

 glsts' Exchange by Mr. Carpenter. Two hundred and sixteen 

 species are enumerated as actually inhabiting Rhode Island. — P. 



Report on the Mollusca of the " Blake " dredgings, pt. ii, 

 Gasteropoda and Scaphopoda, by W. H. Dall. (Bull. [NIus. Comp. 

 Zool., vol. xvii, 8vo., pp. 492, 31 plates.) This Report together 

 with that upon the ' Blake ' Pelecypoda published about two years 

 ago, constitutes, we do not hesitate to say, the most important single 

 contribution ever made to American Malacology. ]More than this : 

 the broad systematic and anatomical knowledge displayed, the sul> 

 stantial additions made to the morphology and phylogeuy of 

 Mollusca, give the work an interest to general biologist and special- 

 ist alike. Nearly 500 species, and 43 divisions of higher value are 

 described as new. It is possible to indicate in this place, only a 

 few points of especial interest. 



The teeth of Toxoglossa are homologous with uncini of other 

 Prosobranchs (p. 62). The line of descent and affinities of Voluta, 

 Lyria, Aurin'ia and VohdoUthes is discussed (p. 144). The family 

 Triforidce is projjosed for Tn'foris (p. 242). Separatista is placed in 

 the family ? Adeorbidce. Our impression is that it will have to take 

 to the road again. No two authors agree as to its family affinities. 

 As to Adeorbis (jf authors, some of its species are certainly rhipido- 

 glossate, while others belong close to or in the Rissoidce. The true 

 family characters of Capulidce (Cajndus) are stated (p. 286). An 

 exhaustive discussion of the nomenclature of Scalar ia Auct. is given
