336 PROCEEDINGS OF THE MALACOLOGICAL SOCIEXr. 



a policy I cannot endorse, they recognized three generic groups in 

 phxce of the twelve mentioned above, but regarded as sub-genera 

 practically all the above and some additional ones. It is quite 

 impossible to criticize thoroughly the treatment, but I cannot, from 

 my studies in Antipodean molluscs, agree with the groups provided 

 in the above-named Monograph. It would be useful simply to 

 correlate the ^Monograph ideas and the List associations, but it must 

 be remembered this is only a superficial resume. I hope to thoroughly 

 study the group at a later date.

Though the associations seen in the List may, and do, need 

 readjustment, the method utilized of expressing the facts is preferable 



to til at of the Monograph. I will only deal here with nomenclatural 

 matters, and will later discuss the relationships. 



Cremula, n.g. 



I propose this name for Turhonilla clavula, Loven (Ofvers. K. 

 Yet. Akad. Forh., Stockholm, 1846 (January 14), p. 49. pi. i, fig. 7: 

 Norway). In the Moll. Keg. Arct. Korveg., November, 1878, p. 205, 

 G. 0. Sars introduced Liostomia for two species — eburnea, Stimpson, 

 and clavula, Loven. In the Nomen. gen. e spec. Conch. Medit., 

 1884, p. 95, Monterosato selected the type as 2\ clavula, Loven. 

 In the Monograph, apparently not recognizing this, the type is cited 

 as ehurnea, Stimpson. As far as I know, .Dall & Bartsch first made 

 this selection in the Proc. Biol. Soc. Wash., vol. xvii, p. 13, 

 February 5, 1904, but that was twenty years too late. In the 

 Treat. Malac, 1840, p. 328, Swainson had employed Sars' 

 selection under the spelling Leiostorna, so that I now make 

 rectification as above. 



Zastoma, nom. no v. 



I propose the above for Brachystomia, Monterosato, Noraen. gen. 



e spec. Concli. Medit., 1884, p. 94, introduced with rissoides,Hvai\(ij, 



as the typical species. In the List this is given generic rank, with 



six species, and Doliella, Monterosato, Bull. Soc. Malac. Ital., vol. vi,
