EEV. O. P. OAMBBID&E ON CEYLON SPIDERS. 393 



the former has no corneous projection at its base, though there 

 is a short curved one near it, connected with tlie palpal organs. 

 These organs consist chiefly of a large, prominent, glossy, and 

 somewhat pear-shaped lobe, marked on its surface with sinuous 

 lines : near the narrow end of this lobe is another of a somewhat 

 cylindrical form, projecting beyond the extremity of the digital 

 joint. The abdomen is rather short, very convex above, and pro- 

 jects greatly over the base of the cephalothorax ; it is of a silvery 

 whitish-yellow colour, with ill-defined intersecting lines, and has 

 on its upperside six perceptible (but slightly defined) raised ob- 

 tuse points — three on either side of the fore half: these points 

 are best seen when the spider is looked at in profile ; the position 

 of each is also defined by a cloudy or blackish spot of greater or 

 less extent upon or near it. The second two of these raised points 

 (one on either side) are connected by a well-defined, curved, 

 strongish black line ; and from the centre of this line a more or 

 less well-defined narrow band of the same colour runs back to- 

 wards the hinder part of the abdomen, narrowing as it goes, and 

 sending out short oblique black lines on each side near its hinder 

 extremity ; a little way behind the last two raised points this band 

 and the two oblique lines join a large, well-defined, somewhat 

 lyre-shaped (in some examples a mere oblong) marking of a deep 

 brownish-black colour, reaching to the spinners, and divided lon- 

 gitudinally by a wedge-shaped more or less regular bar of silvery 

 spots. The underside of the abdomen is brown-black, marked 

 with some silvery bars and spots forming a broken curved line 

 on either side from the spiracles to the spinners, encircling which 

 the two lines unite. From near the spinners a broad slightly 

 curved bar of black-brown, narrowing gradually, runs along the 

 side of the abdomen ; and beneath this is another of somewhat 

 the same character, but shorter and less conspicuous. Some little 

 variety exists in different individuals in the degree of distinctness 

 and extent of the above-described pattern : in the male it is alto- 

 gether less distinct than in the female, and in some examples 

 of the latter sex the central longitudinal black bar on the upper- 

 side sends out other lateral oblique lines besides the two above 

 mentioned ; in other examples the transverse curved bar is either 

 very faintly defined or entirely obsolete. 



Eleven individuals (ten $ adult and immature, and one c? adult) 

 were contained in Mr. Nietner's Ceylon collection.
