158 STALK-EYED CRUSTACEA 



spine situated very near the spine upon the external angle 

 of the orbit ; lower down, upon the pterygostomian region 

 and obliquely under the fourth, there is another small 

 spine. I'^ront spiny, divided by a very narrow fissure 

 continued backwards in a deep groove. Orbital borders 

 spiny ; two spines stronger than the others upon the 

 superior border, separated by a wide fissure. Posterior 

 borders long, straight, and oblique. 



Legs of the first pair of unequal size ; fourth joint 

 with granular borders ; fifth spiny outside ; hands with 

 spines upon the borders and upon their external face in 

 eight rows ; internal face smooth ; fingers strongly toothed 

 terminating in a point, that of the movable fingers cross- 

 ing that of the fixed fingers on the inside. Walking legs 

 long, the second pair being longer than the first. 



All the back is covered with long red hairs. 



Range. — Guadaloupe.

Pihimnus gracilipcs . A. Milne Edwards, Miers. 



Resembles Pilunuuis aciilcatiis. The carapace is much 

 thicker and more quadrilateral than usual ; it is covered 

 with short hairs, claviform, and scattered so as not to hide 

 the details of the surface. The regions are a little rough 

 from the punctures out of which the hairs spring. The 

 front is wide and formed of two spinous lobes, slightly 

 bowed in front. The internal orbital angle has two spines. 

 The superior orbital border is unarmed, it is scarcely cut 

 by a few pointed granulations ; the inferior orbital border 

 has about four spines, and terminates in an internal angle 

 with two spines. There are some spiniform tubercles and 

 a number of granulations upon the subhepatic and ptery- 

 gostomian regions. The antero-lateral borders are short
