1874.] REV. O. P. CAMBRIDGE ON NEW DRASSIDES. 391 



dark-coloured and slightly the smallest of the eight : the rest are 

 pearly white ; each of them is separated from the hind central eye 

 nearest to it by an interval equal to its own diameter ; and the height 

 of the clypeus is as nearly as possible (in the middle) equal to a 

 similar interval. 



The legs are not very long, but rather strong ; their relative length 

 is 1, 4, 3, 2 ; they are of a pale dull yellow-brown colour, furnished 

 witli hairs and a few spines on those of the third and fourth pairs ; 

 each tarsus ends with two curved pectinated claws, beneath which is 

 a small claw-tuft ; and the hairs beneath the tarsi are numerous, short, 

 and tolerably compact. 



The palpi are short but moderately strong ; the radial is slightly 

 shorter than the cubital joint and has its outer extremity prolonged 

 into a strong apophysis as long, or nearly so, as the joint itself; this 

 apophysis tapers at first, but enlarges again near its extremity, 

 which is obliquely truncate. The colour of the palpi is like that of 

 the legs, and they are furnished with hairs and a few spine-like 

 bristles, but the radial and digital joints are darker ; the latter joint 

 is of ordinary oval form and rather longer than the radial and digital 

 joints together. The palpal organs are simple. 



The falces are rather short, straight, strong, slightly projecting 

 forwards, and prominent near their base in front ; their colour is a 

 dark red-brown, and they are furnished with strong prominent 

 black bristles. 



The maxillae are strong, curved, inclined towards the labium, 

 broadly impressed across the middle, and obliquely truncated at their 

 extremities. 



The labium is oblong, and reaches to the inner extremities of the 

 maxillae ; its colour is deep yellow red-brown, that of the maxillae 

 being darker. 



The sternum is oval, pointed behind, slightly truncate before, and 

 similar in colour to the cephalothorax. 



The abdomen * is oval, truncate before, moderately convex above ; 

 it is of a dull yellowish-white colour, clothed with dark sooty brown 

 hairs, and numerous strong upturned black bristly hairs just beneath 

 the fore extremity, which projects over the hinder slope of the 

 cephalothorax. Spinners short and of a yellow-brown colour ; those 

 of the inferior pair are longer and stronger than those of the superior 

 pair. 



A single adult male was received from Mr. J. T. Moggridge, by 

 whom it was found among the debris of an old wall, and kindly sent 

 to me from Mentonein February 1874. In its general structure and 

 colours it is of ordinary character; but the radial apophysis is peculiar, 

 somewhat resembling that of D. troglodytes (Koch) as well as that 

 of D. morosus (Cambr.) and D. bulbifer (Cambr.), and will serve to 

 distinguish it at once from other species. It is a smaller Spider than 

 B. troglodytes, with which, or with either of the others mentioned, 



* In some other examples received since this description was written, the 

 abdomen has several pale angular bars or chevrons (the vertices of which are 

 directed forwards) on the hinder half of its upperside.
