OX NEW AND RARE BRITtSH ARACtlNIDA. 59 



is a dull yellow-brown, the ocular area suffused with black, and, 

 as well as the upper part of the clypeus, furnished with numerous 

 bristly hairs, those on the clypeus just below the ocular area 

 upturned. 



The Eyes are rather large and occupy the whole of the fore 

 extremity of the caput. The posterior row is very nearly 

 straight ; its very slight curve has its convexity directed forward ; 

 the hind-central pair are separated by a diameter's interval from 

 each other and by at least one and a-half diameters from the 

 laterals. The fore-centrals are wide apart on somewhat tuber- 

 cular prominences, and with the hind-centrals form a quadrangle, 

 whose fore-side is much longer than the hinder one. 



Fakes, maxillcc, labium, and sternum are yellow-brown. 



Legs, moderately long, i, 4, 2, 3, furnished with hairs only, 

 and of a pale-yellow hue. 



Palpi similar in colour to the legs, short, the cubital joint 

 much rounded, or nodiform above, the radial short, broad, and 

 spreading, in a somewhat mushroom form. The digital joint is 

 very large, obtuse, oval ; the palpal organs simple. 



Abdomen short oval, very convex above, and projecting over 

 the base of the cephalothorax. Colour dull black, and clothed 

 thinly with coarse hairs. 



A single example of this species, which differs from all the 

 others of the genus known to me, was found under a piece of 

 rock near Pennsylvania Castle, Portland, in June, 1904, by Dr. 

 A. Randall Jackson. 



Tmeticus firmus, sp. n. PI. A, Figs. i3A, 138, 130. 



Adult male, length i line ; adult female, length i line. 



Cephalothorax, short, rounded in front, a little longer than 

 broad ; upper convexity uniform ; height of clypeus consider- 

 ably exceeds half that of the ocular area. Lateral marginal 

 impressions at the caput scarcely perceptible. Colour pale dull 

 yellow tinged with brown, and a few coarse hairs among the 

 eves.
