 with feebly swollen tips one-third to one-half webbed, the web 

 extending as a fringe along either side ; no subarticular tubercles ; 

 a large oval, flat, inner metatarsal tubercle ; tibio-tarsal articu- 

 lation reaching to nearly, or quite, the commissure of the jaw ; 

 tibia one-third to two-fifths in length of head and body; foot 

 longer than the head. Upper eyelid with conical tubercles, one 

 of which is enlarged to form a short horn ; an oblique glandular
