82 CARCINOLOGTCAL STUDIES. 



the lioruy , spoonlike excavated tip the inner margin of 

 this finger is armed moreover with five or six very small 

 teeth , which are smaller than the opposite teeth of the 

 index. The excavated tips of the fingers have horny mar- 

 gins and are somewhat hairy. 



The upper margin and the infero-internal margin of 

 the arms of the anterior legs of the female are clothed 

 with rather long hairs, but their under surface is quite 

 glabrous , smooth , without a patch of hair. The inner 

 margin of the wrist is also hairy. The hands measure 

 scarcely two thirds of the length of the carapace , they are 

 much smaller than those of the male and have a different 

 form. The fingers are namely quite as long as the palm, 

 the outer surface of which is minutely granular. The upper 

 margin of the palm presents a longitudinal row of small 

 granules ; a granulated ridge proceeds on the outer surface 

 of the palm close to and parallel with the under margin 

 and is continued as a smooth ridge on the immobile finger 

 to the tip. Immediately below this ridge the lower margin 

 of the index is longitudinally sulcate. The upper margin 

 of the dactylus is also longitudinally grooved. The outer 

 surface of the fingers appears smooth, the dactylus has no 

 denticulated lobe before the middle , but both fingers are 

 armed with a few very small teeth , which are slightly more 

 distinct on the lower than on the upper finger. The inner 

 margins of the fingers are hairy along their distal half. 

 The smooth inner surface of the palm does not present 

 the patch of hair , which exists in the male. 



The meropodites of the other legs are pubescent along 

 their upper margin and armed with a spiniform tooth a 

 little before the distal end ; for the rest these legs have 

 the form and structure , proper to allied species. 



The two largest individuals have the following dimen- 

 sions :
