measures 15'5 millim. long and 13 wide, is much flatter than 

 in the females. The tarsus of the palp is apically truncate, the 

 bulb is furnished with a stout shortish process, which seems 

 to be semicircularly curved when viewed from the outside, 

 its internal edge being carinate. 



Unlike the male of Omothi/mus^ there is no trace of a 

 process on the tibia of the first leg.

? . — Colour. Carapace, abdomen, and limbs clothed with 

 yellowish-grey hairs ; the abdomen and posterior legs finely 

 spotted with black spinules,the former with an obscure, median, 

 fuscous, longitudinal stripe and transverse fuscous stripes 

 parting from it : legs apically redder, the long sette on legs 

 and abdomen yellowish red ; apices of femora, patellte, tibige,

 than wide, the radiating grooves shallow ; the fovea straight, 

 conspicuous, with anterior and posterior walls nearly in con- 

 tact, not so wide as the ocular tubercle ; ocular tubercle about 

 one third wider than long, its front edge close to edge of 

 carapace ; the width of tlie clypeus not more than half the 

 diameter of anterior median eye; the anterior lateral eye 

 separated from the edge by a space which is distinctly less 

 than its long diameter. Eyes large, the anterior row pro- 

 curved, the median the largest, the distance between them 

 equalling about half their diameter and equalling the distance 

 between the median and lateral; the lateral not much more 

 than half the size of the median, elliptical ; the posterior 

 lateral about as large as the anterior lateral and the same 

 shape, the distance between them a little less than their short 

 diameter; posterior median largish and closer to the lateral 

 than to the anterior median. 



Maridihle furnished below with a series of 14 teeth bound- 

 ing the internal edge of the inferior area; this area granular
