with one another by a longer, piliferous, elevated line, which 

 proceeds close to and parallel with the anterior margin. The 

 under (external) margin of the outer surface is likewise hairy 

 and armed with some small spinules, which gradually change into 

 piliferous tubercles or elevated lines at the proximal end. The 

 inner surface of the arm is quite flattened and smooth, and the 

 somewhat convex under surface is somewhat granular, and covered 

 with rather long hairs. 



The whole upper surface of the carpopodite is everywhere 

 covered with piliferous acute tubercles, which gradually change 

 into acute spinules towards the margins ; thus the internal margin 

 is armed with two parallel rows of about 11-12 acute spinules, the 

 foremost of which is a little larger than the others. The much 

 smaller internal surface of the wrist, which is also covered with a 

 few piliferous, smooth, and depressed tubercles, gradually passes 

 into the still smaller concave and smooth under surface. 



The compressed hand is a little longer than high, the propor- 

 tion of its length (the fingers included) to its height being 

 about 12 : 9 ; the lower margin of the immobile finger is in a 

 straight line with the lower margin of the palm. The whole, 

 scarcely convex, outer surface of the palm is covered with small, 

 more or less acute tubercles, which are all piliferous, like those of 

 the preceding joints. These small tubercles gradually change 

 into spinules towards the comparatively short upper margin, 

 which therefore presents two parallel rows of small spinules, an 

 external of eight, and an internal row of five spinules. The 

 under margin of the palm is covered with acute tubercles 

 similar to those of the outer surface. Towards the index these 

 tubercles are arranged biserially close to one another, and this 

 double row proceeds upon the under margin of the immobile 

 finger. The inner surface of the hand also presents some 

 sparsely distributed, piliferous tubercles. The fingers are rather 

 much compressed, and there is no gap between their inner 

 margins. Their outer surfaces present some more or less acute 

 piliferous granules, but their inner surfaces are nearly smooth, 

 though somewhat hairy, especially the inner surface of the index. 

 The upper margin of the mobile finger is armed with a row of about 

 16-17 acute piliferous spinules, which gradually diminish in size 

 towards the pointed, somewhat hooked tip ; at the inner side of 

 this row, a second row of much smaller spinules is seen on the 

 upper margin of the thumb. The inner margins of the fingers
