Addis on E. Verrill, 



distance from its base there is a light obtuse protuberance, or 

 rudimentary spur. 



The telson is wide and tapers but little; distal width to length 

 as i : 2 ; proximal width to length as I : i.io; distal end is obtusely 

 rounded, its angles are obtuse and bear two minute unequal spines.

 Dominica Island. Frontal parts much enlarged. 



In the subspecies elongatus the carpocerite is more slender and 

 its spine considerably exceeds it in length. The rostrum and 

 orbital spines are longer and more acute, while the rostrum is 

 decidedly longer than the orbital spines, nearly equalling the first 

 antennular segment. 



Coutiere records this species from many places, ranging from 

 both coasts of Florida to Porto Rico and St. Thomas, from low 

 tide to 28 fathoms ; and as subspecies elongatus from South Caro- 

 lina, Florida, Venezuela, Jamaica, to Bahia and Desterro, Brazil. 

 The Yale Museum has specimens from Fort Macon, N. C, speci- 

 men figured (No. 1831,* coll. Dr. Yarrow). Coutiere mentions 

 a single male from Lower California not distinguishable from 

 Florida specimens. I have from Dominica Island a specimen 

 differing somewhat from the type (var. caribcea, new, pi. 39, figs. 



* A closely related form, considered a new variety, which occurs off 

 Fort Macon, N. C. (var. carolincnsis Ver.)
