ser. Ill, vol. \i, p. 22, July, 1860) for apparently the same group. 

 I believe Dall & Biirtsch in this case are right, but as another 

 synonym (p. 192) they cite " Pti/chostomon, Locard, Prod, les Moll. 

 France, 1886, p. 22?^. Type Turbo conoideus, Brocchi ". In this 

 they are wrong as, though Locard proposed Ptychostomon without 

 designating a type, he used it generally for the smooth Odostomia, 

 which name is missing. Upon reference to p. 571, Locard explained 

 that Ptychostomon was proposed as a new name for Odostomia, Fleming, 

 1819, on grounds of purism. The type of Ffijchosfomon is, then, 

 lurho pUcaUis, Montagu. 



Kobelt has used Locard's emendation, disregarding all laws of 

 nomenclature, the family name becoming Ptychostomida;. Many 

 years previously, however, a general substitute for Odostomia had 

 been proposed by Clark (Jeffreys, Brit. Conch., vol. iv, p. 109, 1867), 

 viz. llotwptaxis, and this would have been available, though possibly 

 purists might make complaint against this even. It is also as well 

 to record that Locard, in his choice of a name, had been long 

 anticipated by Ptychostomum, Stein, Sitzung. Bohm. Ges. Wiss., 

 vol. Ixi, I860'. 



Pyegisculus, Monterosato. 



This name would replace Pyrgostelis, Monterosato (Nomen. gen. 

 e spec. Conch, ilcdit., 1884, p. 89), which had as type Mel. rufa, 

 Philippi, regarded in the List as a var. of iniert-upta, Totten, as it 

 was proposed in the same place, on tlie previous page, for scalaris, 

 Philippi, which is here classed with it. Dall & Bartsch, liowever, 

 do not consider these two should be placed in the same sub-genus, 

 but admit two different sub-genera for them, Pyrgiscus and Pyryisctdiis, 

 placing them under TurboniUa. 



Pyrgiscus was introduced by Philippi in the Archiv fiir Nat. 

 (Wiegm.) 1841, p. 50, apparently as a substitute for lurbotiilla, 

 Risso, but Dall & Bartsch have used as type of this the species 

 rufa, and consequently, if their action be correct, Pyrgostelis, 

 Monterosato, is an absolute synonym of Pyrgiscus. 



NOEMIAMEA. 



Oda was proposed by Chaster (Journ. Conch., vol. x, p. 8, January, 

 1901), on Monterosato's suggestion, to replace Noeniia, De Folin, 

 " as this name is preoccupied in the coleoptera," citing Odostomia 

 dolioliformis, Jeffreys, in this connexion. It is accepted as a sub- 

 genus of Odostomia bj- Dall & Bartsch, while Noemia and Noemiamea 

 are included in the synonymy of Chrysallida, Carpenter, the type 

 being given of Noemia as Noemia angusta, De Folin. 



I have already indicated errors in connexion with Dall & Bartsch's 

 quotations ex Les Funds de la Mer. Mr. Alex Beynell has lent me 

 a number of parts of the first volume of Les Fonds de la Mer, and 

 from them I find that this journal came out in livraisons in the order 

 they appear according to pagination. Consequently the name Noemia 

 depends upon its first introduction, which was in connexion with the 

 species Noemia valida (Folin, Fo7ids de la 2fer, vol. ii, p. 63, pi. ii,
