240 Indian Arachnoidea. [No. 4, 



The falces are as compared with the size of the spider large, con- 

 siderably higher than the front side of the thorax, yellowish, with 

 brown short and thick claws. 



The lip is very small, semicircular ; the maxillae considerably larger, 

 wide at the base, subtriangular, and converging with their ends ; the 

 palpi are inserted at the upper bases, they are equal to double the 

 length of the falces. The lip is brownish, the maxillae and palpi 

 yellowish, the last being only at their extreme tips brown. 



The sternum is sub-oval, somewhat truncate in front, very little longer 

 than the falces, and of greyish brown colour. The feet are of moderate 

 size, their proportionate length is as 1, 2, 4, 3, the 2nd and 4th being 

 subequal, and the 3rd equal to two-thirds the length of the fourth ; 

 all are uniformly yellowish, brownish at the tips of the tarsi, each of 

 which is supplied with 4 very minute claws. 



Abdomen sub-pentagonal, truncate in front and slightly covering the 

 base of the thorax, widest and subangular in the middle, obtusely pointed 

 and somewhat raised posteriorly. The general colour is brownish, mark- 

 ed all over with small white specks, posteriorly with a central longi- 

 tudinal somewhat branching line, and laterally with a few indistinct 

 transverse dark spots. The lower side is brownish, with four silvery 

 white spots, forming a quadrangle between the epiginium and the 

 spinners ; the former is very little, the latter are strongly prominent, 

 and of considerable -length. The whole of the body, including the 

 thorax and the feet, is thickly covered with somewhat elongated white 

 hairs.
