92 ON NEW AND RARE BRITISH ARACHNIDS. 



directed backwards ; each lateral pair is seated on a low 

 tubercle ; the quadrangle formed by the central four is rather 

 broader than long ; its fore side much the shortest, and the 

 eyes of this side are much the smallest of the four ; the size of 

 the rest is nearly or quite equal ; the interval between the 

 hind-central pair is rather greater than that between each and 

 the hind lateral next to it. Excepting the fore-centrals, 

 which are dark coloured, all the rest are of a bright pearly 

 white. 



Legs of moderate length and strength, apparently 4, 1, 2, 3, 

 furnished with hairs, a very few spiniform bristles, and a long 

 slender prominent spine from the upper side of the tibiae of 

 the fourth pair. The colour of the legs is like that of the 

 cephalothorax. 



Palpi similar in colour to the legs. 



Falces rather strong, straight, vertical, similar in colour to 

 the cephalothorax. 



Maxillce short, strong, similar in colour to the legs, inclined 

 to the labium, which last is very short, blunt pointed at the 

 apex, not more than half the length of the maxillae, and 

 impressed across the middle. 



Sternum large, as long as broad, truncate before, drawn 

 into a broad point at its hinder extremity, and of a dull yellow- 

 ish colour clouded with brown. 



Abdomen (rather mutilated) somewhat oblong-oval, and of 

 a dark dull blackish hue. The genital aperture formed by 

 a long very characteristically shaped process (see figure 22a). 

 Received from Mr. D. R. Packe Beresford, Fenagh, Ireland, 

 genus appears doubtful.
