tion, therefore, of two (if not three) uew species will be of interest 

 to arachnologists. 



Eriodon formidabile, iiw sp. PI. IX. figs. 1-6. 



<J adult? Length \2\ lines. 



Cephaloihorax broad, smooth, shining, entirely free from hairs, almost 

 squarely truncate in front, flattened behind in thoracic portion ; caput 

 rises almost perpendicularly from thorax, length of its base occupying 

 nearly two-thirds of the length of cephalothorax, occiput rounded, 

 upper part of caput forms a level platform occupied by the eyes. 



Eyes very minute, in three groups ; a group of three in a triangle occu- 

 pies each upper fore corner of caput, and midway between these two 

 groups two other eyes form a third; the eyes of this third group 

 are near the fore margin of caput, but not so near it as is the foremost 

 eye of each of the lateral triangular groups ; these two foremost eyes 

 slightly the largest of the eight. 



Legs short, very strong, especially those of third and fourth pairs* fur- 

 nished sparingly with hairs, fine granulations, and a few very short 

 spines on metatarsi, tibiee, and genua of third pair ; spines on tibia; 

 form a transverse row near their fore extremity ; legs of hinder 

 pair were wanting in the specimen described ; relative length a])peared 

 to be 4, 3,2, 1. 



Falces very strong and massive, nearly equal to cephalothorax in length; 

 they occupy the whole breadth and depth of caput ; profile arched. 

 A powerful slightly curved, black fang folds, when at rest, obliquely 

 inwards beneath falces ; inner sides and extremities of falces furnished 

 with long dark golden-brown hairs ; near extremities on inner side a 

 cluster of black spines similar to those on falces of species of Cte- 

 niza (Latr.) ; these spines are almost hidden by hairs. 



Maxilla broad, massive, nearly straight, obliquely truncate at extremi- 

 ties, leaving outer extreme corners long and round-pointed, furnished 

 with hairs, like falces, especially on their inner sides and towards ex- 

 tremities. 



Labium, long, narrowish, straight, slightly rounded at apex, which 

 reaches just to the inner and upper corner of maxillse, and is, like 

 them, furnished with hairs. 

 Sternum. Owing to peculiar insertion of labium, sternum appears to be 

 strongly notched at upper end ; it is of a broad oval form, rather 

 broadest behind ; some grooves, which radiate towards centre, corre- 

 spond to the number of legs. 

 The colour of all the above parts is a deep rich brown tinged 

 with reddish ; legs rather the darkest. 



Abdomen. This, though shrunken, appeared to be small, and of a 

 dark sooty-brown colour, sparingly furnished with coarsish hairs; 

 spinners 6, short, two outer ones very strong.
