304 MOLLUSKS OF BERING SEA. 



others. Yet this name has attained general currency, because (proba- 

 bly) of an attempt of the brothers Adams in their " Genera " to treat 

 Stromhella Schleuter as having entered into nomenclature. 



In the Annales de la Societe malacologique de Belgique (iv, 1869, j). 20) 

 Morch cites '■'• Fusus {Pyrolofusus Beck) deformis'''' from Spitzbergen. 

 But Beck's name does not appear in any publication previously, and is 

 not defined or characterized here or elsewhere by himself or by Morch. 

 In April, 1873, the writer characterized the subgeneric group, which 

 includes Neptunea liarpa Morch and Fusus deforme Gray, under the 

 name of Heliotropis, with the first-mentioned species as type. If he 

 had known of Morch's citation of Beck's manuscript name, he would 

 have adopted it, not because it had any right to stand, but to save a 

 synonym. 



Against this case is a similar one, which should meet with the same 

 treatment whatever may be the decision. In 1879 there were distributed 

 to all persons known to be interested in northern mollusks a set of 

 plates belonging to my report (unavoidably delayed in MSS.) ou the 

 Biiccinido! of the Alaskan fauna, some fifty copies iu all, properly 

 lettered with the names of the species by the engraver. I had found 

 on dissection that the rhachidian tooth of the radula in Chrysodomus 

 crebricostatus Dall (1877) was smooth and flat (as in Liomesus), and in- 

 tercalated iu the legend of the plate the subgeneric name Beringius for 

 this species, in recognition of this feature, which was fully character- 

 ized and figured in my manuscript. Subsequently my friend, Mr. 

 Friele, in his researches on the mollusca of the Norwegian North At- 

 lantic Expedition, discovered the same peculiarity in Fusus turtoni, 

 which he accordingly separated under the name of J umala. 



Now, I am far from claiming that if the other characters coincide 

 Beringius should take precedence of Jumala ; on the contrary, I be- 

 lieve it should not, and that Mr. Friele's name should stand; but it 

 would seem as if one rule should apply to all cases of the kind, and 

 that the unrecognizable names of Schleuter an<] the undefined catalogue 

 entries of later writers, such as Pyrolofusus and Volutopsius, should 

 not be quoted to the discomfiture of more conscientious or more thor- 

 ough workers, or gain, bj^ their mere existence, any standing in nomen- 

 clature. 



Cerithiopsis (stejnegeri, var. ?) truncatum, n. s. (PI. IV, fig. 5). 



Among the small shells inhabiting the canals of Cliona and other 

 ''bread-sponges," and not found elsewhere, was detected at Unalashka 

 a small Cerithiopsis very similar in sculpture to C. stejnegeri, but dis- 

 tinguished by a remarkable peculiarity not noticed in any other species 

 of the genus known to me. The nuclear whorls, amounting to one and 

 a half, were of a (for the species) very large size and of a soft, almost 

 fleshy, consistency ; in drying, this broke up spontaneously and disap- 

 peared. The first shelly whorl is about the size of the fourth whorl iu
