The second legs have the merus twice as long as the first carpal 

 article, which is about one-fifth shorter than the total of the other 

 four articles. The terminal claw is longer in the male but shorter in 

 the female than the last four carpal articles and is tufted with setae. 



The third legs are also stronger in the male than in the female ; the 

 merus is about three and one-half times longer than wide; the pro- 

 podus is armed on its inferior lateral margin with eight sharp spines ; 

 the dactyl is short, curved, subequally bifid.

Plates 66, 67. 



Type: This exquisitely sculptured species was taken by the "Blake" 

 at six stations in the "West Indies, at depths ranging from 322 to 955 

 fathoms. The type material is divided between the Museum of Com- 

 parative Zoology and the Paris Museum. 



Distribution : Known throughout the West Indian region, from 

 the above cited "Blake" stations in the upper West Indies to the 

 "Challenger" record, off Pernambuco. The "Pawnee" captured 49 

 specimens of this species in the vicinity of Glover Reef, in 484 fms. 



Material examined: Thirteen specimens, four of which are ovig- 

 erous, dredged in 1100 fathoms, off Miami, Florida, March 3, 1926, by 

 the "Ara," establishes the most northern record for the species, as 

 well as the greatest depth at which it has been captured. 



Technical description: Animal 88.5 mm. long; rostrum 15 mm. 

 long from tip to postorbital angle; carapace 22.5 mm. long from or- 

 bital angle to posterior margin. Abdomen about 51 mm. long. 



Rostrum sharp, recurved and convex for the anterior three-fifths of 

 its length, the proximal part broad, concave, widening posteriorly, 

 ornamented with a pair of spines, one on each margin, anterior to the 

 eyes and a second pair posterior to the orbital angle and just in ad- 

 vance of the first transverse groove. There are eight longitudinal 

 carinae on the carapace, the submedian pair of which are continuous 

 with the posterior lateral margin of the rostrum and which is com-
