1874.] REV. O. P. CAMBRIDGE ON NEW DRASSIDES. 373 



G.plumalis (Cambr.) and G. exornata (Koch), was received in a 

 fine collection of spiders kindly made for me in the Bombay Presi- 

 dency by Major Julian Hobson, H.M.S. Corps. 



Gnaphosa procera, sp. n. (Plate LI. fig. 2.) 



Adult male, length 4 lines (very nearly). 



This Spider, in size, general form, structure, colours, and markings, 

 is exceedingly like G. cambridgii (Cambr. & Koch), G. lunata 

 (Cambr.), G.'kochii (Cambr.), and G.conspersa (Cambr.) (see "Spid. 

 e f Palestine and Syria," P. Z. S. 18/2, pp. 227-230), but may be at 

 once distinguished by the form of the palpi ; these are rather short 

 and strong. The radial is of the same length as the cubital joint, and 

 there is but little difference in their strength ; the former has its 

 outer extremity prolonged into a short, slightly bent, strongish, 

 tapering, sharp-pointed, red-brown, corneous-looking apophysis, of 

 about half the length of the joint itself, and contiguous to the base 

 of the digital joint ; these joints are furnished with hairs and strong 

 bristles. The digital joint is large, and rather exceeds in length 

 that of the radial and cubital together ; its form is oval, gradually 

 drawn out at its fore extremity. The palpal organs are well deve- 

 loped, and composed of various curved corneous spines and processes, 

 not easy to be described differentially, but seen at a glance to be 

 different on comparison with those of the other closely allied species ; 

 one conspicuous spine issues from the middle near the base of the 

 palpal organs, and, curving over round their inner side, terminates in 

 a sharp point near their outer extremity. 



The cephalothorax is yellow, lightest towards the margins, which 

 are bounded laterally by a black line ; the sides have some blackish 

 irregular markings ; and two curved lines run backwards from the 

 hind lateral eyes, converging to the thoracic junction. 



The legs, palpi, falces, maxillce, labium, and sternum are also 

 yellow, the falces, however, being suffused with red-brown ; and 

 the digital joints of the palpi of a brownish hue. 



The abdomen is of a clear straw-yellow colour, marked above with 

 small black spots and points ; those along the centre are mostly in 

 parallel pairs, forming two irregular longitudinal rows ; others are 

 more thickly scattered along the margins, whence some run over upon 

 the sides in curved oblique rows; and near the base of each of the 

 superior and inferior spinners is a larger black spot or blotch, finish- 

 ing on each side the two hinder oblique lateral rows ; along the cen- 

 tral line of the fore half is a rather tapering oblong yellow-brown 

 marking. The underside is unspotted. The superior pair of spin- 

 ners are small and short, less than one third the length of those of 

 'the inferior pair. The abdomen in the present species is more clearly 

 and distinctly spotted, and less liable, apparently, to crowding, or 

 to suffusion and running together than in the others. 



The female is rather larger than the male, but resembles it exactly 

 in colours and markings ; the form of the genital aperture is exceed- 

 ingly like that of the female of G. cambridgii ; and should the two 

 species ever be found in the same locality, it will require great care
