fingers are shorter than the palm, for the greater part glabrous, greatly compressed, sharply 

 crenulate at inner margins, back of mobile finger and under margin of opposite one with a row 

 of hairs, which are much longer on the movable finger; in the cT the fixed finger does not 

 present a longitudinal row of hairs. 



Walking legs not much elongate. Outer margin of carpo- and propodite and inner 

 margin of latter fringed with the usual, club-shaped hairs; penultimate pair of legs with some 

 scattered hairs only, propodites of this pair longest, narrowing distally; dactyli as long as 

 preceding joints, styliform, hairy, little curved, those of last pair shortest, straight, but curved 

 upward near the tip. 



First abdominal segment of both sexes very broad, reaching to the bases of the last 

 pair of legs, but almost linear, third segment in cT (fig. 3 b) little produced laterally, remaining 

 segments gradually narrowing. 



This species in its general appearance seems nearest to T. niarginata, of which no 

 figure as yet is published, but in the new species the antero-lateral margins are obtuse, and 

 present three blunt, widely-separated teeth instead of the apparently closely-grouped, denticulate 

 teeth of Miss Rathbun's species; the carapace of T. transversa is wider, the eyes are not 

 prominent and dark. In both these species the fronto-orbital distance is approximately one-half 

 of the greatest breadth of the carapace.

This species is characterized by the following points : 

 1" The whole animal, at least the adult 9i is covered by a short, ruddy-brown pubescence; 



the long, feathered hairs along the margins of the carapace and along all the legs are of 



the same colour. 

 2" The greatest breadth of the carapace is only 1.2 times the length, so that the animal is 



much narrower than the preceding species; the fronto-orbital breadth is nearly exactly one-half 



of this greatest breadth (according to Miss Rathbun's measurements the width across front 



and orbits is less). 

 3" The lateral margins of the carapace are more strongly pronounced than in T. iransversa, 



and, when cleaned, present two very faint notches, widely separated; behind the last 



notch the lateral margins are parallel or even slightly divergent backw'ard, widening again 



a little above the bases of the last legs.
