CURRENT LITERATURE. 



Pilsbry, Henry A.— Tryon's ALmual of Conchology, ser. ii, vol. xiv (pt. 53), 

 pp. I — 64, pis. I — 15. Philadelphia: Academy of Natural Sciences. 



In the present part Dr. Pilsbry completes the account of the genus Amjjldclromus, 

 Alb., treating of the subgenera Bccldomca, Nev., and Pseuclopartula, Pfr. ; then 

 conveniently follow the following genera: D rccparnaudia , Montr., with D. crossci, 

 n. sp. from New Caledonia, which stands between D. sinistrorsa, Desh., and D. 

 lifuuna, Pils., this latter being a new name for the D. theohaldianus, Gass., preoc- 

 cupied by Benson. The genus is perhaps most closely related to Pcqndna than to 

 any other genus. A new subgenus ( Dolicheulota) of Eulota, Hartm., is described, 

 the author here remarking that the anatomy, at present unknown, will probably be 

 found to agree essentially with Euhaclva. The type is Buliimis formosensis, H. 

 Ad., but as the name is preoccupied in Eulota, it is suggested that if on examination 

 of the anatomy a new one is required, it may be termed E. eloiigata. Calycia, H. 

 Ad., and the somewhat unsatisfactory genus Bocourtia, Rochebr., follow. 



Passing then to the American Bulimulidae, the subfamily Odontostominae is first 

 dealt with. That the genera treated of are Bulimuline is unmistakably indicated by 

 the exceedingly short kidney, and by the absence of accessory organs upon the 

 penis. Mncrodontes, Swains., is accorded generic rank, then follow Anctus, v. 

 Marts., and Odontostomus, Beck, with the fiillowing sections: Moricandia, Pils. 

 and Van., Bahicnsis, Jouss., Cyelodoiitina, Beck, and Odontostomus, Beck, s. str. 



Hedley, C. — Studies on Australian Mollusca. Part iii. Proc. Linn. Soc. N. S.W., 

 1900, pp. 721 — T2)2, pi. xlviii, and 8 figs, in text. 



The following new species are described and figured : Mathilda rosae, Leuconopsis 

 inermis, Stenothyra australis, Iravadia australis, CaUomphala globosa, Endodonta 

 concinna, Chlamys fencstrata. In addition to these, figures are given of many other 

 species, particularly interesting amongst which is that of Asa^ihis contraria, Desh., 

 a new and unexpected addition to the Australian fauna.
