AND A NEW GENTJS OE ABANEIDEA. 403 



Lahiuni elongate-oval, pointed at the apex ; this part, together with 

 the falces, maxillae, and palpi, are rather paler in colour than 

 the cephalothorax. 



Sternum furnished sparingly with short hairs, and of a yellowish 

 colour : the peculiarity of the absence of a regular sternal plate 

 has been noticed above in describing the mode in which the 

 legs are articulated to the sternal surface. 



Abdomen long and narrow ; at least three times the length of the 

 cephalothorax, to which it is equal in breadth at its fore 

 extremity ; thence it narrows a little ; but quickly enlarging 

 both laterally and above, it then lessens gradually to its hinder 

 extremity, which is abruptly truncated, the upper margin being 

 a little prominent and furnished with a rather dense fringe of 

 coarsish yellow-brown hairs. The colour of the abdomen is a 

 dull brownish yellow, freckled and spotted with whitish creta- 

 ceous-looking spots and markings, and each side has a blackish 

 patch near the elevated part ; a narrow longitudinal dull brown 

 band or streak bisects the upperside, fining down to a slender 

 line near the spinners ; from this streak, a short one on either 

 side branches off at the broadest part of the abdomen, and a 

 little further on a slender line of a similar colour issues at first 

 obliquely on either side ; and then running nearly parallel to 

 the central streak, each joins, in an acute angle near the extre- 

 mity of the abdomen, another fine oblique line emanating from 

 the medial line. The abdomen is clothed, but not very densely, 

 with short yellowish-brown, yellowish-grey, and whitish hairs, 

 mingled with which are a few short stumpy, but not strong, 

 black spines or spiny bristles. The underside has a broad longi- 

 tudinal medial brownish band, bisected throughout its length 

 by an irregular streak composed of whitish-yellow spots. Spin- 

 ners prominent ; consisting of the normal 3 pairs with a super- 

 numerary one, very short and of a large somewhat curvilinear 

 triangular surface, immediately beneath the rest (respecting 

 its peculiarities see above, characters of genus) ; the superior 

 pair are longest and triarticulate, the central pair small and 

 not easy to be seen; close above the superior pair, near the 

 anus, is a longish slender biarticulate (?) process, surmounted 

 with hairs and a compact group of spines. 

 An adult female of this remarkable spider was received from 



Mr. Gr. II. K. Thwaites, among many other new and rare species 



kindly collected for me early in the past year in Ceylon by that
