AMPELISCA GA1MARDTI. 131 



having the posterior margin fringed with long plumose 

 hairs ; the wrist is short, scarcely longer than broad, and 

 having the posterior margin fringed with long plumose 

 hairs ; the foot is three times as long as the wrist, it 

 has the margins almost parallel, tapering towards the 

 distal extremity; the outer margin, towards the distal ex- 

 tremity, has long plumose and a few short simple hairs ; 

 the inner has, at the same extremity, four or five short 

 stout spines : the finger is longer than the hand, very 

 slender, and almost straight ; it is capable of impinging 

 laterally against the inner margin of the hand, the apex 

 reaching beyond the wrist. The fifth pair of legs have 

 the second joint dilated, oval, being enlarged as much 

 anteriorly as posteriorly ; the fourth and fifth joints are 

 subequal in length and size ; the latter terminates ab- 

 ruptly, and has the extremity furnished with five or six 

 short blunt spinules, subapically tipped with a single 

 cilium, and a few long hairs, which have their margins, 

 for nearly the distal half, serrated deeply ; the foot is 

 much narrower than the wrist, but is quite as long, it 

 has the margins almost parallel, the extremities being a 

 little narrower than the diameter of the middle of the 

 joint; the anterior margin is furnished with a row of 

 equidistant, short, obtuse-pointed spines, subapically 

 tipped with a single cilium ; towards the extremity of 

 the foot the spines gradually increase in length and in 

 sharpness, until on the apex they pass into the character 

 of hairs ; the posterior margin has the distal half mi- 

 nutely crenulate, and armed with three spines, which 

 gradually increase in length and strength the nearer 

 they approach the finger, in the last of which the sub- 

 apical cilium has increased in strength until it has be- 

 come as important as the primary division ; the finger
