g6o American Work on Recent Mollusca in 1881. [December, 



icism of several papers by Streenstrup and Owen, published 

 nearly simultaneously with the earlier parts of Verrill's work, 

 thereby causing some entanglements in nomenclature, for an 

 account of which the reader is referred to the paper itself. Sev- 

 eral new names appear in this appendix, e. g. Brachio ten this 

 {bcanii V.) g. et sp. n. from fish stomachs off Martha's Vineyard ; 

 Chirotatthk lacertosaY . n. s. for a form from the eastern coast of 

 North America of which a fragment was referred to C. bonplandi 

 by Verrill in the Bull. Mus. Comp. Zo61ogy. vm, Mar. 1881 ; 

 Stoloteuthis (cf. antea) ; Inioteuthis n. g. with /. japonic a and 

 /. Morsel V. spp. n. from Yedo Bay, Japan, collected by Professor 

 Morse. Then follows a conspectus of the families, genera and 

 species of Cephalopods included in this paper, specimens of all 

 of which, except Taonius pavo, have been examined by the author. 

 The plates reflect much credit on the artist, Mr. Emerton, those 

 which are lithographed coming out with particular beauty. 



"Some notes on American land shells" (i-II, pp. 8 and 13, 

 Journ. Cincinnati Soc. Nat. History, iv, Oct. and Dec, 1881). In 

 these papers Professor A. G. Wetherby discusses the habitat, 

 location, synonyms, etc., of a large number of species of pulmon- 

 ates. Ariolimax var. hecoxi is proposed for a form from Califor- 

 nia which appears to differ from A. coluwbianus. When fully 

 extended, living specimens reach nine inches in length. An 

 albino variety of Helix fidelis is noted from Washington Terri- 

 tory. In the second part the molluscan fauna of Roan mountain, 

 North Carolina, is considered, and Helicodiscus fimbriauts n. s. is 

 described (p. 9, separate copies). Patula sampsoni is proposed 

 as a name for a form closely allied to P. dorfe miliaria Lea from 

 Eureka Springs, Ark. The paper closes with an appeal to and 

 some instructions for collectors. 



In the American Journal of Science (Volume XXII, pp. 41 i- J 4. 

 Nov, 1881), Professor Verrill briefly reviews recent papers rela- 

 ting to the East American invertebrate fauna. 



Professor Angelo Heilprin (Proc. Acad. Nat. Sci, Phil., Dec, 

 1 88 1, pp. 423-28) publishes " Remarks on the molluscan genera 

 Hippagus, Verticordia and Pecchiolia," in which he calls attention 

 to and details the confusion existing in regard to these genera, 

 without, however, finally resolving the difficulties. He is dis- 

 posed to retain Hippagus as distinct from Crenella (to which it 

 has very generally been referred), on the ground that the shell
