The cephalothorax is oval, convex, glossy, pointed in front, 

 and without an indentation in the medial line : the falces are 

 short, conical, vertical, and somewhat divergent at the extremity : 

 the maxillse are enlarged and convex at the base, rounded at the 

 extremity, and curved towards the lip, which is triangular ; and 

 the sternum is oval, with minute eminences on the sides, oppo- 

 site to the legs : the legs are moderately long, and provided with 

 hairs and fine spines ; the fourth pair is the longest, then the 

 first, and the third pair is the shortest ; each tarsus is terminated 

 by two curved, pectinated claws, and below them there is a small 

 scopula. These parts, with the palpi, which are inserted near 

 the middle of the outer side of the maxillse, are of a dull yellow 

 colour, the sternum, which has some long dark-brown hairs on 

 its margin, being the palest. The abdomen is oviform, convex 

 above, and projects a little over the base of the cephalothorax ; 

 it is clothed with short hairs, and the upper part is of a pale 

 red colour; the under part has a yellowish-white hue, faintly 

 tinged with red ; the sexual organs, which are not highly deve- 

 loped, are of a pale red-brown colour; the spinners have a pale 

 yellowish-brown hue, and the two inferior ones are terminated 

 by long soot-coloured papillae. The eyes are closely grouped on 

 the anterior part of the cephalothorax; four form a straight 

 transverse row immediately above the frontal margin, which is 

 fringed with long hairs, the two intermediate ones being the 

 largest of the eight ; the other four are placed in pairs directed 

 obliquely inwards, behind each lateral eye of the front row; 

 the three lateral eyes are near to each other, and form a short, 

 slightly curved line whose convexity is directed outwards, and 

 the posterior eye of each has an oval figure. 



An adult female of this species was taken in a house among 

 specimens of fossils. It appears to be most nearly allied to the 

 Enyo amaranthina of JM. Lucas, but differs from it in various 

 particulars.

The legs are moderately long, provided with hairs and spines,
