I. '21. 7 



the rest of the joint is covered with rounded tubercles. The 

 propodite is large and fairly smooth, being covered only with 

 minute granules, except on the inner edge, which is lined with 

 small teeth. The edge of the dactyl also bears a row of teeth, 

 which are small and rather blunt. The palm is longer than 

 the fingers, which are acuminate. The cutting edges of the 

 fingers are furnished with irregular calcareous teeth. The 

 borders of the palm are parallel, but, opposite the base of the 

 dactyl, the outer margin bends outwards, so that the axis of 

 the fixed finger makes an obtuse angle with the long axis of the 

 palm. 



The right cheliped is very small compared with the left and 

 is densely setiferous. The merus is laterally compressed and 

 its sides are covered with scales bearing radial groups of setae 

 (not shown in the figure) ; there are a few teeth on the outer 

 lower edge. The carpus is also compressed and bears a dorsal 

 row of five to seven teeth, which increase in size distally. There 

 is a very obscure parallel row of indistinct points outside this. 

 Teeth are scattered irregularly over the upper surface of the 

 propodite and dactyl. The palm is much shorter than the 

 fingers, which end in sharp claws. The under surface is almost 

 or quite smooth, and the dactyl is strongly curved. 



The first right walking leg is laterally compressed. The 

 merus is almost smooth on its inner side ; on the outer side 

 it bears some scale-like tubercles with setae. On the upper 

 and lower edges there are similar tubercles. The carpus has 

 a few setiferous tubercles on its outer surface, and more on 

 the upper surface, on the middle of which there is a row of 

 teeth increasing slightly in size anteriorly. The inner surface 

 is smoother and flatter than the outer. The propodite is 

 slightly curved and bears a few tubercles or scales on the inner 

 surface. On the upper edge there is a row of about twenty 

 small teeth interspersed with setae. On the outer surface 

 there are a few scales dispersed in longitudinal lines. The 

 dactyl is longer than the propodite, is curved and slender, 

 and ends in a yellow claw. It is slightly grooved on the outer 

 side. There are no spines on the lower edge, but there are 

 four or five longitudinal rows of hairs which are most plentiful 

 on the inner side. 



The other walking legs resemble that just described, except 

 in the following points. In the first left walking-leg the teeth 

 on the carpus are larger, and in second left walking-leg these 

 teeth and those on the propodite are feebler. 



The fourth pereiopods are of the usual form covered with 

 long plumose setae and with a broad imbricate area on the 

 propodite. They are almost perfectly chelate. 



The fifth pereiopods are larger than the fourth, and are min- 

 aitely chelate. 



There are four unpaired pleopods, none of which is biramous. 



The uropods are of the usual form. 



Size :°^The carapace. usually measures about 8-10 mm.
