abundant at several stations from about the latitude of Cape Cod, 

 southward to the coast of Carolina, with a few specimens off Florida. 

 It sometimes occurs in very considerable numbers and usually at 

 moderate depths. In reviewing the literature the species does not 

 seem to have been recorded in any recognizable form outside this 

 general area. 



The figures given by Bailey, while somewhat crude, show very 

 well the general character of this species, and his designation of its 

 occurrence, together with the very adequate description, make no 

 question about referring these specimens from our Atlantic coast 

 to his species.

Description. — Variety differing from the typical in the somewhat 

 smaller size and the development of numerous acicular spines about 

 the early coiled portion. 



Distrihution. — Goes described this species from the Caribbean Sea 

 in 196-210 fathoms (359-384 meters). I have had this variety from 

 but one station in the material of the Albatross dredgings, which I 

 have studied. This is from off the southern coast of Florida. It is 

 to be suspected that the one station given by Flint from the northern 

 part of the Gulf of Mexico for MarginuliTia ensis may be this 

 variety. This variety evidently replaces the typical form in warmer 

 waters.
