Pholcus distinctus, n. sp. PI. XI. figs. 28, 29, 30. 



Eesembling the foregoing species in size and general appear- 

 ance, the present one diifers in the relative position and size of 

 the eyes, as well as in the form of the abdomen and markings. 

 The eyes of the lateral groups are smaller than in "P. Oeylonicus,^* 

 and the two small eyes of the intermediate group are situated 

 perceptibly helow the line of the lower eyes of each lateral group. 



The colour of the cephalothorax is yellow, with an irregular 

 longitudinal central band and a lateral one on either side of the 

 thoracic region, of a dark blackish-brown colour. The clypeus 

 has two blackish lines, one from the outer side of each eye of the 

 central pair, perpendicular to, and terminating at, the base of the 

 falces. Ocular region suffused with brown. Falces yellow. 

 Sternum wholly dark brown. Abdomen narrow, oval ; loolted at in 

 profile, it slopes in a curved form to the spinners ; its colour is 

 pale yellowish, marked above and on the sides irregularly, though 

 somewhat obliquely, with dull black. An irregular longitudinal 

 central band of a similar colour occupies the underside. Tlie 

 sexual organs differ totally in form from those of "P. Ceylonicus" 

 and want the epigyne. The palpi are furnished with long dark 

 bristly hairs, and terminate with a tuft of shorter black ones. 



The collection contained a single adult $ of this species. 



Genus Argteodes.

$ adult, length 2| lines. 



Cephalothorax longish oval, rather flattened ; fore part of caput promi- 

 nent, and divided transversely by a deep fissure into two lobes, the 

 lower one of which is the strongest ; these lobes are both furnished 

 with strong prominent bristly hairs, especially the upper one, the 

 hairs upon which are chiefly directed forwards over the fissure : the 

 normal grooves and indentations are strongly marked, especially that 

 defining the junction of the caput and thorax : the thorax (in profile) 

 is slightly raised above the profile line of the caput : the cephalo- 

 thorax is of a yellow-brown colour ; its margins, indentations, and a 

 longitudinal central line upon the caput are suffused with dusky. 



Eyes in four pairs,^upon, and at the base of, the hinder lobe of the 

 caput ; not very unequal in size ; one pair (largest of the eight), seated 

 near its fore extremity, and another pair a little way behind them form a 

 square ; and at some little distance below, on each side, behind the 

 base of the fissure, is another pair, the eyes of which are contiguous 

 and seated on a small tubercle.
