1869.] Indian Arachnoidea. 245 



between the lateral and the posterior central eyes is almost greater 

 than that between the latter and the anterior centrals. 



The falces are little shorter than the thorax, somewhat depressed, 

 furnished with very strong, slightly curved claws lying in grooves pro- 

 vided with strongly serrated edges. 



The lip is small, roundish at the tip ; the maxilla? narrow, flattened, 

 with their terminations curved outwards, and nearly double the length 

 of the lip. The palpi are thin, about half as long as the falces, thickly 

 set with blackish hairs, especially towards their ends. 



The sternum is oval, somewhat elongated, sub-truncate in front and 

 pointed behind, slightly emarginated at the places where the coxae 

 are inserted ; the latter being rather thickened. The feet are of the usual 

 proportionate length, the first being by far the longest (equal to double 

 and a half the length of the abdomen and thorax together) ; then 

 comes the fourth, then the second, the third being scarcely longer than 

 the abdomen. The colour of all the parts mentioned is a pale brown, 

 darker about the region of the eyes, on the falces, on the lip and at the 

 terminal joints of the feet ; the maxillae are pale. 



The abdomen is subcylindrical, perfectly separated from the thorax, 

 anteriorly slightly thicker, and posteriorly curved upwards : dark brown, 

 finely reticulated with a silvery whiteness throughout ; along the cen- 

 tre of the sides runs a narrow thin black line, accompanied above and 

 below by a distinctly whitish undulating line ; another white line is 

 seen along the lower margin of the abdomen, and the central portion 

 of the latter is occupied by a black band ; a very conspicuous white 

 spot is situated laterally near the base of the spinners, which are 

 dark brown and very little prominent ; the epiginium is small, the 

 trachean opercula large, subtriangular, rather distant from the ante- 

 rior end ; both are of a light brown colour. 

 Length of cephalothorax 2.4 m.m. ; its width 1.3 m.m.
