EURYCOPE CARIBBEA Benedict. 



Eurijcope caribbea -Benedict, in Ivicu akdsox, Proc. U. S. Nat. Mus., XXIII, 1901, 

 pp. 558-560. 



Locality. — Windward Islands, West Indies. 



Depth. — 687 fathoms. 



The head is much wider than long. From the point between the 

 antonnuhe a depression curves backward and outward to the post- 

 lateral margin. On the base of the head is a short, transverse, tuber- 

 cular ridge. Two oblong, low tubercles are situated closely behind 

 the peduncles of the antennulte. The sides of the head are swollen. 

 The peduncles of the antennte and antennula? occupy a space inclosed 

 by the front and sides of the head; the margin surrounding these 

 appendages is strongly raised. 



The front of the head running between the antennul* has the 

 appearance of a rostral point; here the raised margins unite in the 

 narrowest place and then immediateh^ diverge and extend downward 

 perpendicularly and around underneath the appendages, where they 

 meet and lap with the produced and bent antero-lateral projections. 

 The first joint of the peduncles of the antenna is very stout, with 

 numerous depressions and prominences; the fourth segment is very 

 long; the terminal i)ortions are broken in all the specimens. The first 

 joint of the peduncle of the antennula is excavated on one side to 

 receive the curvature of the antennal peduncle; the other segments of 

 the peduncle are very small; the Hagellum is long and slender, with a 

 great number of articles. 



The first segment of the thorax is very narrow; nearly the whole 

 surface is occupied by a transverse groove; on the median line and 

 posterior ridge is a prominent granule; the antero-lateral angles of 

 this segment are rounded. The second, third, and fourth segments 

 are also short and have deep transverse depressions which are nmch 

 narrower than the one in the first segment; on the median line of these 

 segments the space between the groove or depression and the anterior 

 margin is occupied by the compressed base of a sharp spine which is 

 directed forward; between the depression and the posterior margin is 

 a compressed protuberance; between the protuberances the transverse 

 groove runs as a narrow cut rounded and enlarged at the bottom. 

 The antero-lateral angles of the second, third, and fourth segments 

 are produced forward in short, sharp spines. 



The epimera of the four anterior segments have projecting spines; 

 the first having a single spine, the other three having two spines each. 

 The three posterior segments of the thorax are very much the same as 

 in E. fi'cujUls; the spines on either side of the median line decrease in 

 size successively. 



The spine on the base of the abdomen is short; there are two con-
