1884.] NEW GENERA OF SI'IDERS. 203 



In this Spider also nre the peculiar pale spines above noted on 

 the upper side of the femora. 



The abdomenh of a uniform black colour; the upper surface and 

 sides towards the hinder part covered with conical tubercles, most 

 of them terminating with a short strong bristle or spine, but some on 

 the sides near the hinder part terminate with a longer, distinct pale 

 spine directed downwards; this deflection, however, may perhaps 

 be only due to accident or some other cause, though I think it is 

 normal. 



It is possible that this Spider may only be the male of O. ceylonica, 

 though, from the difference in the size of the eyes, as well as from 

 the remarkable differences in colour and markings, I am inclined 

 to think it a distinct species. 



A single example was received from Ceylon from Mr. Thwaites, 

 and another from Major (now General) Hobson from Bombay some 

 years ago. 



Fam. Cryptothelid^e. 

 Regilltjs, gen. nov. 



Cephulothoraxl&vge, a little longer than broad, somewhat flattened, 

 deeply indented ; thorax round ; caput short, and constricted on 

 the margins before. 



Eyes 8, small, and not differing greatly in size ; disposed in two 

 very slightly curved transverse concentric rows, the convexity of the 

 curve directed forwards ; the anterior row is shortest ; the figure 

 therefore described by the two rows is the frustum of a cone. 



Legs strong, moderate in length, 1, 2, 4, 3, those of the first pair 

 considerably longest and much the strongest ; they are tuberculose 

 and furnished with strong spines, springing from the tubercular 

 prominences ; two parallel rows of strong ordinary spines are disposed 

 longitudinally beneath the tibise and metatarsi of the first and second 

 pairs ; others (some semidiaphanous) more prominent, long, obtuse 

 and occasionally clavate at their extremities, are irregularly disposed. 

 The tarsi end with three claws — the two upper claws (each appa- 

 rently furnished with a single tooth only), and beneath them is a 

 very small one, difficult to be seen. 



Fakes straight, a little retreating, not very long nor strong. 



Maxillce short, straight, slightly leaning over the labium, pointed 

 on the inner and rounded on the outer extremity. 



Labium short, broad, rounded at the apex. These parts were 

 difficult to observe. 



Sternum short-oval. 



Abdomen truncate before, broadest and obtuse behind. The whole 

 of the upper surface and sides covered with strong prominent spines 

 of various lengths, some pale and semidiaphanous, others brown and 

 black, some obtuse at the end, others clavate. The whole Spider is 

 thus of a very hirsute and bristling appearance. The spinners are 

 short, closely grouped together, and almost entirely concealed by a 

 marginal series of long coarse hairs which converge over them ; I
