A male (No. 3119, Yale Mus., pi. xxvi, fig. 1) and a female of this 

 rare species were taken by our party in 1898. They have been studied 

 by Miss M. J. Rathbun, who furnished the following notes on them: 

 "The 5 is 7.2 ram long and 10.2 mm wide. The outer face of the hands 

 in the male is almost entirely smooth, as in the 9 , only the upper 

 and proximal portion being spinulous; the outer and upper surface 

 of the wrists is entirely covered with spmules or sharp granules. 

 The upper surface of the carapace is rough with scaly granules, 

 which, on the hepatic region, are developed into sharper and higher 

 projections. The lobes of the front slope backward a little from the 

 middle, where they are separated by a V-shaped notch; the margins 

 of the lobes are nearly straight, and the little tooth next the orbit is 

 scarcely separated from the rest of the margin. The outer orbital 

 tooth and the next antero-lateral tooth are very small, but plainly 

 marked and acute ; below and between them there is a sharp sub- 

 hepatic tubercle ; the last three antero-lateral projections are sharp 

 subequal spines. The ambulatory legs are very slender." 



To these characters it may be added that the front is strongly 

 bent downward, and there is a narrow transverse ridge at the bend, 

 nearly parallel with the edge ; the upper margins of the orbits are 

 minutely denticulate ; the sharp granules of the carapace and chela? 

 bear hairs, while many much finer hairs arise between them ; the 

 legs are covered above with long slender hairs; their merus joints 

 have a row of small sharp spines along the front edge ; the carpal 

 joint of the chelipeds has a distal transverse groove, and two sharp 

 spines on the anterior edge ; the manus of the smaller chela has a 

 slight dorsal groove bordered by rows of sharp granules; the dactyl us 

 has two distinct dorsal grooves, and the thumb one on each side, 

 below. On the larger chela, which is much stouter, the grooves arc
