 mon to tbe Antilles and the Gulf of Mexico, and has been found on the 

 west coast of Florida, in 50 fathoms.

Hab — Gulf of Mexico to the Antilles, in deep water. Station 2751, 

 south of St. Kitts, in 687 fathoms, ooze ; and Station 2754, east of To- 

 bago, in north latitude 11° 40', west longitude 58° 33', in 880 fathoms, 

 ooze; temperatures 38° to 40° F. 



Tbe figures of this species heretofore given having all been made 

 from young and immature specimens, it was thought well to figure the 

 complete adult shell from some fine specimens collected near St. Kitts. 



The specimen figured measures IS" 1 " 1 in length; the largest (but not 

 perfect) specimen obtained must have reached a length of 23 im ". 



Mangilia exsculpta Watson. 

 M. exsculpta (Watson, 1882) Dall, op. cit., xvin, p. 117, PI. xi, Fig. 9, 1889. 



Antilles, Challenger and Blake, collected by the Albatross at Station 



2750, off St. Bartholomew, West Indies, in 496 fathoms, sand ; Statiou 



2751, south of St. Kitts, in 687 fathoms, ooze; and Station 2754, east 

 from Tobago, in 880 fathoms, ooze ; temperatures 37°.9 to 44°.4 F. 



This is a very peculiar looking shell. The specimen figured in the 

 Blake report is only a young specimen. Those obtained by the Albatross 

 were much larger and finer. 



Subgenus CALLIOTECTUM Dall. 



Shell with a vernicose epidermis, short, undifferentiated canal and no 

 anal notch or fasciole; operculum with apical nucleus, increasing like 

 that of Fusus, but curved instead of straight, though not coiled ; animal 

 blind, with a short sac like proboscis, with no teeth or poison gland. 

 Type C. vernicosum Dall, abyssal. 



Calliotectum vernicosum, sp. uov.
