Epimerals of moderate size. Lateral margin of head salient. Feet of 

 first pair rather large, fourth and fifth joints broad, and taken to- 

 gether oblong oval, below hirsute, fourth joint a little the longer, 

 rounded at lower apex, fifth a little oblong, finger a little shorter 

 than fifth joint (hand). Feet of second pair very stout, the hand 

 (fourth joint) very large, oblong, immoveable finger stout, rather 

 short, bidentate, the extremity of the hand not extended beyond 

 base of this finger, fifth joint thick, nearly twice as long as the sixth, 

 below much hirsute, hairs as long as breadth of joint. Feet of fifth

Length, three lines. The epimerals of the thorax are distinct, and 

 the second and third are nearly as long (vertically) as broad. The 

 finger of the first pair of legs is fine serrulate within, and at apex of 

 hand there are hairs as long as the finger. The finger of the second 

 pair has some hairs near its extremity, which are as long almost as 

 the finger. The fifth joint, where it articulates with the hand, is more 

 than half the breadth of the hand. The six posterior legs have 

 longish hairs towards apex of joints, with some others on the inner 

 margin, which are quite short. The tarsi have no seta below towards 

 apex. The branches of the first pair of stylets have about four short, 

 stoutish setae on the margin, besides the apical.
