and the centrals of the hinder row the smallest of the eight ; each 

 liind lateral eye is very near to the hind central on its side : the eyes 

 of the front row are very close above the insertion of the falces. 

 ie^s rather long, strong; relative length 4, 1, 2,3; the difference be- 

 tween those of the 4th and 1st pairs consists in the respective lengths 

 of their tibia; and metatarsi ; they are rather paler in colour than the 

 cephalothorax, and are furnished with hairs, bristles, and strong 

 spines : the tibiae of the legs of the first pair are somewhat enlarged at 

 their fore extremities ; on the inner side below the enlargement they 

 are armed with a long, strong, slightly curved, and rather obtusely 

 pointed black spine : each tarsus ends with two strong, curved, 

 thickly pectinated claws, beneath which is a third, smaller and abruptly 

 bent downwards. 



Palpi : these issue from the extremities of the maxilla;, and are long, 

 similar in colour to the legs, and furnished with hairs, bristles, and 

 slender spines : the radial joint is nearly equal in length to the hu- 

 meral ; it is very strong, and somewhat convexly oval, or tumid, in 

 form ; near the outer extremity of this joint is a sort of depression, 

 close to which are two clusters of short strong spines ; the cluster 

 nearest to the digital joint consists of a compact group of four spines, 

 the other cluster contains a greater number, but they are shorter, and 

 their points converge towards each other : the digital joint is short, 

 broader at its extremity than at its base ; the former is emarginate : 

 the palpal organs consist of a small, irregularly globular, corneous 

 bulb, prolonged into a longish sinuous projection, which terminates 

 in a slender sharp point directed outwards. 



Falces strong, rather prominent and arched in front ; similar to the ce- 

 phalothorax in colour ; furnished with hairs and a small group of not 

 very conspicuous, short, black spines at their upper extremities. The 

 falces are about equal to the caput in length. 



Maxillce strong, straight, divergent, and with a slightly prominent 

 point at their inner extremities near the articulation of the palpi. 



Labium short, narrower at the apex than at the base ; the former rather 

 roundly truncate : the junction of the labium and sternum is deeply 

 depressed. 



Sternum oval ; broader and more pointed behind than in front ; this 

 part (with the maxillae and labium) is furnished with hairs, and is si- 

 milar in colour to the legs and palpi. 



Abdomen oval ; of a dark blackish-brown colour tinged with yellow 

 above ; beneath it is yellowish ; it is not quite equal to the cephalo- 

 thorax in length, and is furnished with hairs and bristles. In the 

 specimen examined the spinners were unfortunately wanting. 



A single adult c? vi'as coutaiued in the collection of spiders re- 

 ceived from Mr. Nietner.
