The end of the antennal peduncle reaches about to the 

 end of the cornea. The process at the outer angle of the 

 of the second joint bears about six sharp teeth on its inner 

 border and a great number of long pinnate setae on its outer 

 and inner edges ; it does not quite reach the end of the fourth 

 joint. There is no spine on the inner side of the second joint 

 at the base of the acicle. The acicle is thickened at the base, 

 very strongly curved, and its apex, which is furnished with 

 two or three short spines, reaches slightly beyond the middle 

 of the fifth joint. On its inner margin there are many setae, 

 some pinnate, some simple. The fourth joint is short and 

 narrowed distally, the fifth slender, somewhat compressed and 

 bearing groups of setae. The fiagellum is setose and longer 

 than the carapace. 



In the right or larger cheliped the merus is stout, rounded 

 above and with low transverse ridges from which setae arise on 

 its upper and outer surfaces. On the lower outer edge there is a 

 row of about ten teeth and two or three on the inner lower 

 edge ; the lower surface is densely setose. The carpus is about 

 the same length as the merus and is more or less flattened 

 above. The upper inner margin is defined by a row of six or 

 seven sharp teeth, largest anteriorly. The upper surface 

 bears scattered teeth, some situated on the distal margin, and 

 many tufts of setae springing from them or from low ^scales. 

 The outer upper edge is rounded and the lower surface is setose, 

 but without teeth. The propodite is nearly twice the length 

 of the carpus and is covered with setae. Occasionally the 

 setae are rather sparse but more frequently they are dense, 

 forming a matted coating, which greatly obscures the features 

 of the surface and becomes thin only in the neighbourhood 

 of the finger tips. Both edges of the propodite are defined 

 by rows of teeth, those on the inner margin stronger than those 

 on the outer. The upper surface bears a number of sharp 

 tubercles which extend on to the fingers ; in the middle of 

 the palm some tend to form a definite longitudinal row. The 

 fingers have yellow corneous tips and are about as long as the 

 palm. The under surface of the hand is almost smooth, with 

 few tufts of setae. Near the cutting edge on the under surface 

 of both fingers a double row of pencils of yellow setae may be 

 seen, each directed towards the other finger. 



The left cheliped is smaller than the right, but is similar 

 in general appearance. The merus is more compressed, with 

 its upper edge better defined, and the carpus has three or 

 four strong teeth on its upper outer edge. The hand is nar- 

 rower, with the dactyl strongly curved and longer than the 

 palm ; the marginal teeth are not strong but there is a distinct 

 median row of tubercles on the palm. In disposition of setae 

 the left cheliped resembles the right. 



The next two pairs of pereiopods are laterally compressed 

 and about equal in length with the large cheliped. The two 

 pairs differ somewhat as regards the arrangement of spines. In
