ments or other processes. The specimen was not a male. The tentacles are 

 not " connate at their bases " in this or the next species, any more than in any 

 other Gastropod with retractile proboscis. The tail end of the foot had no fila- 

 ment, but was (in spirits) merely narrow and pointed. Fragments of this 

 fine species, readily recognized by its polished surface, were obtained as above, 

 and one broken but living specimen at Station 293.

I doubt the identity of this species with that of Hinds from West America, 

 but in any case the name and excellent figure of Orbigny have precedence, 

 though the text of his description was delayed. I have no doubt that Mr. Tryon 

 was correct in uniting the Phos grateloupianus of Petit with his P. antillarum. . 

 Most of the Antillean specimens are more like the figure of the former, said to 

 be from Senegal, than like the pattern of that from the West Indies. There 

 is probably some error about the figure or the habitat. 



There is a small variety of this shell which is brighter colored and more 

 finely sculptured than the more common form, but they intergrade. There is 

 much variation in regard to the presence and position of varices, which are 

 often entirely absent on the upper whorls. The operculum is like that of 

 Chrijsodomus or Phos senticosus. 



The nucleus is glassy, sharply peripherally carinate, and has three to five 

 otherwise nnsculptured whorls. The soft parts and operculum are exactly like 

 those of Phos Beaui, but there is less of the blackish dotting, even the siphon 

 has not much.
