60 CARCINOLOGICAL STUDIES. 



mented, behind the external orbital angles, anteriorly 

 with three small granules, placed at some 

 distance from one another. The postero-lateral margins are 

 slightly concave. The pterygostomian regions are smooth : 

 a few granules are only observed quite near the inferior 

 orbital margins. The endostorae is distinctly ridged. Sternum 

 and abdomen are punctate , but for the rest smooth ; the 

 penultimate joint of the abdomen in the male is somewhat 

 broader than long. 



The anterior legs are unequal both in the male and in 

 the female. The larger hand (fig. 3) is very thick and 

 its outer surface very convex; the latter is covered every- 

 where, as well on the upper as on the lower margin, with 

 numerous granules, which are not arranged in transverse 

 series, but irregularly. These granules are rather sharp 

 close to the articulation with the wrist, but they become 

 gradually more numerous , smaller and more obtuse towards 

 the fingers. The fingers are short, smooth and not grooved ; 

 a few very small granules are only seen quite at the base 

 of the dactylus, when observed under a magnifying-glass , 

 and these granules are placed in a transverse row. 



The granules , with which the smaller hand is covered , 

 are less numerous , larger , conical , acute and more 

 or less arranged in transverse rows. The dactylus is some- 

 what hairy at the base and presents here two or three longi- 

 tudinal rows of acute granules ; similar granules are also 

 found at the outer surface of the immobile finger, which 

 is slightly grooved. The larger hand is only slightly hairy 

 on the proximal half of its outer surface , but the outer 

 surface of the smaller hand is hairy until the base of 

 the fingers. The fingers are black, with white pointed tips ; 

 each of them is armed with two or three white teeth.
