as usual. The upper surface of the carapace is furnished 

 with tufts of setae, which become sparse and finally extinct 

 9ii'the flanks. 



The abdomen is well developed and of the usual form. The 

 telson is asymmetrical, narrow, and short. 



The eyestalks are stout, and are slightly dilated, both at 

 the distal end and at the base. The corneal area is fairly 

 large and is deeply pigmented ; the part of the unpigmented 

 surface, which encroaches on the dorsal surface of the cornea, 

 is shallow and pointed. The ophthalmic scales are rather 

 small, and have sharp tips, which are furnished with a few 

 radiating setae. There are also three or four groups of setae 

 on the upper surface of the eyestalks. The end of the cornea 

 reaches just beyond the base of the third joint of the anten- 

 nular peduncle (extended to its full length), and does not reach 

 the end of the fifth joint of the antennal peduncle. 



The joints of the antennular peduncle are slender, cylindrical, 

 and smooth. The third joint, which is the longest, is slightly 

 thickened at its distal end. 



The antennal scale is long and narrow, and bears a number 

 of stiff setae ; it is swollen and rounded at the base, and its 

 tip extends slightly beyond the middle of the fifth peduncular 

 joint. The external fixed process of the second joint reaches 

 only a short distance beyond the base of the fourth joint. 

 The flagellum is about three and a half times as long as the 

 carapace, and is setiferous. 



The right cheliped, which is much larger than the left, is 

 nearly three times as long as the carapace. The hand lies 

 in an almost horizontal plane. The merus is massive and 

 much thickened distally. The upper surface and sides are 

 covered with low transverse scales, the lower surface with 

 tubercles. Its whole surface bears tufts of setae. There is a 

 row of teeth on the upper distal edge. The carpus is very 

 slightly longer than the merus and is flattened dorsally. 

 The upper surface is covered with rough tubercles, which are 

 replaced by large spines on the inner margin. From the 

 base of each of these there springs a group of setae of 

 varying length. The surface of the palm of the propodite 

 is gently convex. This joint is very slightly longer than 

 the carpus as a rule ; sometimes the two are practically 

 equal. The outer edge is curved, and bears a continuous 

 row of strong teeth. The dorsal surface is covered with 

 rough tubercles tending to become spinous. From the base 

 of each tubercle there springs a bunch of setae, sometimes 

 short, sometimes fairly long, but never so long as those 

 on the carpus. There is no definite arrangement of the 

 tubercles on the propodite, except that sometimes there is 

 a slight resemblance to the two converging rows seen in 

 Eupagurus Bernhardus. The fingers are acuminate, and are 

 tipped with yellow claws. The outer edge of the dactyl is 

 furnished with a row of small but sharp teeth; its upper
