4" In the (yoiing) cf there is a distinct speek of pigment a little beyond the middle of the 

 inflated eye-stalk, but in the 9 t^'s pigment is altogether absent. Miss Rathbun denies the 

 presence of pigment also in the (aduU) cT- 



5" The external maxillipeds are more slender than in T. transversa and do not completely 

 close the buccal cavity, the antero-external angle of the merus is not produced, but 

 well marked. 



6" Chelipeds very much pubescent. Meropodite unarmed; inner angle of wrist pronounced, not 

 IDroduced ; chelae equal in size, both in my young cT and in the 9 1 but very unequal, as 

 Miss Rathbun observes, in the adult cf ; palm sharply keeled at upper and under border, 

 granulate and hairy at outer surface, in the adult 9 with a bare patch in the middle, inner 

 surface smooth and bare in both sexes ; fingers glabrous, shorter than palm ; fixed finger 

 greatly compressed and high at the base ; movable finger with a row of long hairs along 

 proximal half of back. 



7" Walking legs short, densely hairy, also the penultimate pair, which is as long as preceding 

 pair; propodites short; dactyli diminishing gradually in length from the first 

 to the fourth pair, those of last pair scarcely curved upward. 



8" First abdominal segment of 9 "ot linear, but in the middle third longer than the next 

 segment, the lateral portions greatly attenuated. Abdomen of cf not different from that of 

 preceding species. 



Miss Rathbun records specimens of this species from the Sulu Archipelago, not far 



from the "Siboga" locality.

This new species is very much alike T. decrescens\ it is even, at least in the specimens 

 of Stat. 274, covered with the same ruddy-brown pubescence, but the following differences are 

 of importance : 

 i" The anterior margin of the carapace is fringed with long hairs, not nearly naked, as in 



T. decrescens. 

 2" The carapace is somewhat broader, its breadth being 1.3 times the length; the fronto-orbital 



distance is distinctly more than half the greatest breadth of the carapace. 

 3" The lateral margins are entire, not notched, and faintly divergent backward. 

 4" The eyes are very distinct, black and terminal. 

 5" The external maxillipeds (fig. 5 a) are broader, the merus is produced at the antero-external 



angle, broader but shorter than the ischium and provided with club-shaped, feathered hairs
