frontal reg'ion is more constricted behind the supraorbital spine. The 

 meral joints of the anibuhitory legs bear small spines. 



Specimens from several stations oif Havana agree in the above vari- 

 ations; also a small specimen from station 2313, otf South Carohna. On 

 the other liand, a male from station iiG42, off Carysfort Eeef, is typical 

 in form, the dorsal prominences being reduced to tubercles. In a spec- 

 imen from station 2152, 2i miles northwest of Havana Light, the orbital 

 spines are broad and triangular, as in typical IE. rastelli/era, but the 

 remaining spines are long and slender, and the legs are spinous.

 cheliped, about 14.5; of first ambulatory leg about 22. Length (of

This species has a deeji median furrow on the rostrum. The pru'oiv 

 bital teeth are directed upward and forward and are separated by deep 

 grooves from tlie rostrum. The hepatic spine is larger and much more 

 inoducedthan the postorbital spine. The median and branchial spines 

 are cylindrical and more prominent than in E. r<(steUifera. There are five 

 tubercles in a transverse line on the gastric region, the outer and middle 

 ones being most prominent. There are a spine and several tubercles on 

 the margin of tlie branchial region; there is also a short pterygostomian 

 spine, the tip of which is visible from above behitid the hepatic spine.
