94 PEARSE. 



less than one-third of the middle of the orbit, and composed of 4 or 5 

 granules (or on one side of one specimen it is broken into 8 smaller 

 granules) ; in iirvillei the line of granules occupies as much as one-half the 

 length of the orbit. The granulation of wrist and hand is finer than in the 

 related species and the granules on the lower edge of the palm are more 

 prominent. The groove of the immovable finger is more deeply impressed 

 at its origin. The fingers are narrower and less flattened; the immovable 

 one has an enlarged tubercle near its middle, and the movable finger has 

 two enlarged tubercles or small teeth, one near the middle and one not far 

 from the tip. The merus joints of the ambulatory legs are not so wide as 

 in urvillei, the difference being most noticeable in those of the last pair.
