232 CARCINOLOaiCAL STUDIES. 



distinctly compressed laterally, a character of which 

 1 made no mention in my description of Heterop. indica. 

 The arcuate mobile finger appears slightly concave 

 in a longitudinal direction on its outer as well as on its 

 inner surface and is smooth everywhere except at the 

 base of the upper margin that appears finely granular 

 when seen under a lens; the inner margin is armed with 

 seven or eight small teeth of somewhat unequal size. The 

 index or immobile finger is also faintly longitudinally fur- 

 rowed on its outer surface and its inner margin is also 

 provided with several (seven or eight) teeth of unequal size. 



The fingers of the smaller hand of the male (fig. Ic) 

 are comparatively a little longer than those of the larger 

 chela, being but little shorter than the palm, and they 

 leave no hiatus between them when closed. For the rest 

 this hand presents quite the same characters 

 as the other, the outer surface of the palm being per- 

 fectly smooth and glabrous, the upper margin being 

 flattened or even slightly concave longitudinally, separated 

 from the outer surface by a longitudinal , more or less 

 distinct crest or edge and appearing more or less distinctly 

 granular when examined under a lens. The fingers are 

 laterally compressed and faintly grooved longitudinally on 

 their outer surface; the mobile finger is finely granulated 

 nearly along its whole upper margin and armed with six 

 or seven small teeth ; the lower finger, finally, has ten 

 or twelve small teeth. The smaller hand oï Heterop. indica, 

 however, was described by me as being covered with dis- 

 tinct granules and with sparsely distributed hairs on the 

 outer surface of the palm. 



In the single female specimen that I have before me , an 

 ova-bearing individual, the cephalothorax is butllVgmm. 

 broad. As in the males the right chelipede (fig. \^) is 

 a little larger than the left. The chelae resemble the 

 smaller hand of the male , but they are somewhat granular. 

 Both hands have the upper margin of the palm distinctly 

 flattened and separated from the outer surface by a gra-
