The name, Fusus , was definitely restricted by Lamarck, in 1801 (Syst. des An. 
sans Yert., p. 82, type, F. longicauda), to the tropical group belonging to the Fasciola- 
ridje ( Colus auth.), and for that group it should be retained. 
This group undoubtedly includes three or more genera, but all these 
generic groups have not yet been clearly differentiated, nor satisfac- 
torily defined. Among our species, we have two that belong to 
typical Neptunea , viz : N. clespecta, var. tornata , (Gould), and N. 
decemcostata. The former was known to Gould only from the Grand 
Bank, and northward, but we dredged it, in 1881, oft' Martha’s Vine- 
yard, station 949, in 100 fathoms. 
From the Gloucester fishermen the typical form of N. despeeta has 
also been received (lot 861). In this, the spiral carinae are much less 
prominent than in the var. tornata. 
Of the group called Sipho by Morch, G. O. Sars, and others, we 
have several species, three of which were known to Gould, viz : *S. 
Stimpsonii (Morch) * = Eusns Islandicus Gould ( non Linne); S. ven- 
* Morch, in Faunula Moll. Ins. Fieroensium, Yid. Med. Xat. Forh., p. 83, 1867, named 
this species thus: " Fusus Stimpsonii (F. corneus Say, Am. Couch.)” This is, so far 
as known to me, the first distinctive name for the species. The name, F. curtus, was 
given by Jeffreys the same year (Brit. Conch., iv. p. 336, 1867), but it was then applied 
particularly to a fossil form, which may or may not be the same as a certain “ North- 
American form’’ referred to in such an indefinite manner that no one but the author
