34 Rev. 0. P. Cambridge on some new 



mous size. These organs consist of a congeries of bold cor- 

 neous spines and processes ; the radial joint is short but wide, 

 and is divided into several prominent apophyses. 



The abdomen is more of an oval form than that of the female, 

 its length being a little greater than its breadth ; the upper 

 surface is thickly covered witli somewhat shining and appa- 

 rently slightly depressed pale amber-coloured spots ; the black 

 pattern so conspicuous in the female is but just traceable in 

 the male, being ill-defined and mostly of a dull yellowish 

 brown colour on a cream-yellow ground, the ground-colour 

 in this sex, however, being of small extent, and assuming the 

 nature of large ill-defined spots. In all the males examined 

 the dark patch at the hinder extremity of the upperside of 

 the abdomen is of a deep blackish brown. 



Adults of both sexes of this very striking little spider were 

 received from Mr. J. 11. K. Thwaites, by whom they were 

 found in the Royal Botanic Gardens in Ceylon. 



Paraplectana decora^ sp. n. (PI. VII. fig. 8.) 



Adult female, length 2| lines (nearly) ; length of abdomen 

 nearly 2 lines. 



The cejplialothorax and falces are of a rich dark red-brown 

 colour ; the caput is broad, massive, well rounded above ; and 

 the height of the clypeus exceeds the length of the figure 

 formed by the four central eyes. 



The ei/es are small, disposed in three widely separated 

 groups ; those of the central group form a small square, whose 

 longitudinal is rather greater than its transverse diameter, and 

 its fore side rather shorter than its hinder one ; those of each 

 lateral pair are seated contiguously on a small tubercle, very 

 near the margin, at one of the fore corners of the caput, and are 

 the smallest of the eight, the hinder ones of the central group 

 being the largest. 



The legs are short, moderately strong, of a yellow-brownish 

 colour, and furnished with Lairs and bristles ; they differ but 

 little in length, those of the third pair being the shortest. 



The paljn are moderate in length, slender, of a pale dull 

 yellowish colour, and clothed with hairs and bristles, a few of 

 the latter having a spine-like character. 



Thefalces are tolerably long, powerful, and nearly vertical 

 in their direction. 



The maxillw., labium^ and sternum are of the normal type ; 

 and their colour is a dark reddish brown, the sternum being 

 nearly black. 



The abdomen is nearly round, being very slightly less
