much more powerful; l)iil Ihe three males like the I'emales were in all oilier 

 respects alike. 



Material. — I have examined seven specimens (4 Ç, 3 c?) ol' Thorell's original 

 ones from Bhâmo in Burma. 



Remarks. — The specimens examined scarcely diller trom Thorell's descrip- 

 tion in any respects bul one; he says namely that the palps are "densissime, 

 omnium suhtilissime impresso-punctati"; he is certainly wrong and has misinter- 

 preted the low granules.

Ocular spots wanting; céphalothorax distinctly longer than broad behind will} 

 median transverse line, curved backwards in the middle, indistinct (i^) or wanting (^), 

 without granules and with fairly long and almost simple hairs. Abdomen with 6 hairs 

 in front of tlie marginal row on median tergites, and at the tip with 'tactile" hairs; 

 the genital area is of the "Birmanicus" type. The minutely granular palps are longer 

 ((^) or shorter ('^J than tlie body; the trochanter is distinctly longer than broad with 

 posterior margin abruptly convex and dorsal surface produced into a conical tubercle; 

 the femur about '2 3 longer than broad, almost as long as, but distinctly narrower than 

 tlie tibia, which has lateral outlines moderately convex (^) or almost circular ((^) and 

 posterior basal elevation very prominent. The hand is 11 ((^) or 1-35 fÇ) broader 

 than tibia, P7 ((^) or 1.6 C^) longer than broad, 1-4 longer than deep and 1-3 longer 

 than fingers. "Tactile" hair of the fourth pair is placed at the base of tarsus ; the 

 tarsus of the first pair is 5 longer than deep and distinctly shorter than the tibia. 



c?. Céphalothorax. — No ocular spots are visible; the cephalothoracic shield 

 is much longer than broad; a not very well marked median transverse line, which 

 is curved distinctly backwards in the middle, is present. The skin appears to be 

 reticulate and the fairly long hairs are provided with a few teeth. 



Abdomen. — The abdomen is scarcely twice as long as broad and fairly 

 depressed; the longitudinal line is very indistinct; the arrangement of the tergal 

 hairs could not be traced in the details, but scarcely differs much from that of 

 Ch. Birmanicus Tlior.; there is at least 6 hairs in front of the marginal row in the 

 median tergites. The tip of the abdomen bears "tactile" hairs. The genital area is 

 of the "Chelifer Birmanicus Thor." type (cf p. 124). 



Antennae — The flagellum consists of four hairs, of which the anterior 

 bears four distal branches ; the lamina interior with thtee dentated lobes and long 

 serrated s|)ine ; the galea is short with a few minute terminal spines. 



Palps (PI. IV, figs. 5 a-b). — The minutely, but distinctly granular palps are 

 longer than the body; the shape as well as the arrangement of the hairs, usual 

 and tactile ones, as well as of the sense-spots of the fingers are scarcely dilTerent 

 from those of preceding species (cf. p. 177). The trochanter, which is 1'5 longer 

 than broad and distinctly narrower than the femur, is beyond stalk moderately
