402 EEV. O. p. CAMBRIDGE ON TWO NEW SPECIES 



forwards almost contiguously, in a line with the body of the 

 spider ; those of the 4th pair are about one-fourth shorter than 

 those of the 1st ; their tibice are long and rather bent ; the me- 

 tatarsi are strong and furnished on their upper sides with a 

 strong calamistrum throughout the entire length of the joint, 

 and on their undersides with a fringe of long coarsish yellow- 

 grey hairs, among which is a longitudinal row of short dark 

 bluntish spines ; the remaining joints of this and the 1st pair, 

 as well as the legs of the 2nd and 3rd pairs, are sparingly 

 furnished with fine yellowish hairs. The legs of the 2nd pair 

 are comparatively slender and not much more than half the 

 length of the first pair j those of the third pair are a little 

 shorter, and less strong than those of the second ; beneath the 

 femora of the 2nd pair is a longitudinal row of slender erect 

 hairs. Each tarsus ends with three strongly curved claws (2 

 superior, 1 inferior), all of which are pectinated but dift'cr in 

 the character and number of their pectinations ; grouped near 

 and around these claws are some spines and bristles of different 

 kinds, which make it difficult to observe the claws without 

 dissection ; there is also a sharp-pointed, nearly straight, and 

 bluntly pectinated supernumerary claw near the other three. 

 The articulation of the basal joints of the legs is very peculiar ; 

 instead of being, as in all others of the Araneidea, arranged 

 round a regular sternal plate, they are simply articulated in 

 two nearly straight lines upon the surface of the lower side of . 

 the ccphalothorax ; 'those of the 3rd pair are the widest apart, 

 and tlioso of tho 4th nearest togctlicr. In colour the legs are 

 similar to the cephalothorax ; but the upper sides of the first 

 pair, together with the genua, and a small patch at the upper 

 extremities of the tibia? of the 4th pair, are strongly suftused 

 with blackish brown. 



Palpi, short, slender, hairy, and terminating with a strong curved 

 pectinated claw, some of the pectinations being very strong 

 and giving it a somewhat clavate appearance. 



Falces not very strong, but projecting ; they have a few small 

 teeth near the extremity on their inner surface, and terminate 

 in a small curved fang, bearing an appearance of blunt den- 

 tation on the basal half of the inner side. 



MaxillcB long, strongish, nearly parallel, the inner margins slightly 

 inclined towards the labium, and obliquely rounded at the outer 

 extremities, where they are broader than at the insertion of 

 palpi .
