than twice as long as broad, entire, smooth ; hand smooth, obso- 

 letely punctate, wholly naked, fingers very much gaping, the supe- 

 rior quite regularly and largely arcuate. Following feet naked, or 

 very nearly so, tarsus short, profoundly two-clawed (an unguiculate 

 spine hardly smaller than the true claw, proceeding from the under 

 surface of the tarsus).

Length one and a half lines. Unlike the pisum, which it resembles, 

 it has a narrow, oblong, and entire carpus. The two claw-like termi- 

 nations of the tarsus are in the same vertical plane, and each is about as 

 long as the part of the tarsus preceding the claw. These legs are with- 

 out hairs, excepting two or three at the extremity of the fifth joint. 

 The upper side of the hand, including the upper finger, is arcuate in 

 outline. The larger hand is not hirsute between the fingers at base, 

 while the smaller is so, and, at the same time, the latter closes so 

 that the fingers are nearly in contact. Looking at the front in 

 a front view, it is seen to be pointed at middle, and rather promi- 

 nently so.
