such of the legs as were still uninjured were two, black and small ; 

 and beneath them is a scopula of short hairs extending backwards 

 over the inferior surface of the joint. 



The palpi are strong and moderately long ; the humeral joint is 

 of unusual strength, being considerably prominent above towards its 

 hinder extremity, lessening gradually forwards ; their colour is dusky 

 yellow-brown. The radial joint is shorter and less strong than the 

 cubital ; it is furnished with numerous strong bristly hairs on its 

 inner side, and has its outer extremity produced into a strongish 

 apophysis, equal to the joint in length, rather enlarged and roundly 

 obtuse at its extremity. The digital joint is large, and its length con- 

 siderably exceeds that of the radial and cubital joints together. The 

 palpal organs are large, highly developed, and very prominent, con- 

 sisting of a large, nearly globular lobe with several dark sinuous 

 markings on its surface, giving the appearance of closely applied 

 spines ; this lobe is rather drawn out at its fore extremity, where it 

 is also apparently slightly cleft or divided. 



The falces are moderately long, rather slender, and nearly vertical; 

 when looked at from in front, the maxillae are seen to extend con- 

 siderably on either side of them ; they are of a dark reddish-brown 

 colour. 



Maxillce long and strong, and very slightly inclined towards the 

 labium ; they are laterally prominent at their extremity on the outer 

 side, and round on the inner side ; the outer profile-line, when looked 

 at with the Spider flat upon its back, is hollow ; the line and im- 

 pression on their front surface is general, but not great. 



The labium is more than half the length of the maxillse ; it is 

 oblong, rounded at the apex, and (with the maxillae) is of a deep 

 yellow-brown colour. 



The sternum is of a rather elongate-oval form ; and its colour is 

 yellow-brown, slightly tinged with reddish. 



The abdomen is oblong-oval, broadest and bluff behind and trun- 

 cate before, where it projects over the base of the cephalothorax ; it 

 is hairy, and its colour is black. The fore half of the upperside is 

 almost entirely occupied by a large patch of a deep reddish brown, 

 shining, coriaceous nature ; this patch is roundly pointed behind, its 

 side margins being also rather rounding, and it lies exactly within a 

 quadrangular figure occupying the largest portion of the fore part of 

 the abdomen, and formed by four pale whitish spots : following the 

 hinder pair of these spots, which are impressed and indicated by 

 white hairs, are two others on the hinder half of the abdomen, rather 

 nearer together, but also impressed, and shown by two short trans- 

 verse lines of white hairs. The spinners are dusky black, not very 

 long, those of the superior pair being very slightly shorter than those 

 of the inferior pair, and not quite so strong : the spiracular plates 

 are large, and of a clear pale yellow colour ; between them the open- 

 ing leading to the spermatic tubes is unusually visible and of a semi- 

 circular form ; this opening is seldom visible in male Spiders, being 

 usually an imperceptible slit. 



A single example of the adult male of this Spider was found among
