Length of the male, ^th of an inch; length of the cephalo-thorax, J,th, breadth, ^th; 
breadth of the abdomen, ^th; length of a posterior leg, gth; length of a leg of the third 
pair, nth. 
The cephalo-thorax is oval, glossy, gibbous near the middle, with slight furrows on the 
sides converging towards an indentation in the medial line ; the falces are strong, conical, 
armed with teeth on the inner surface, and have a small, conical protuberance in front, near 
the extremity, towards the inner side ; they are slightly inclined towards the sternum, which 
is broad and heart-shaped ; the maxillae are inclined towards the lip, which is semicircular 
and prominent at the apex. These parts are of a dark-brown colour, the falces and maxillae 
being the palest. The legs have a yellowish-brown hue, and the posterior is rather longer 
than the anterior pair; each tarsus is terminated by three claws ; the two superior ones are 
curved and pectinated, and the inferior one is inflected near its base. The anterior eyes of 
the four forming the trapezoid are the smallest of the eight. The palpi resemble the legs in 
colour, and the radial, which is rather stronger than the cubital joint, projects two minute, 
pointed apophyses from its extremity; one situated in front, and the other, which is the 
smaller, on the inner side; the digital joint is oval, convex and hairy externally, concave 
within, comprising the palpal organs; they are moderately developed, complicated in structure, 
with a curved process at the base, directed outwards, and a small, black, pointed, curved spine 
at the extremity; their colour is red-brown. The abdomen is oviform, convex above, pro¬ 
jecting over the base of the cephalo-thorax; it is thinly clothed with hairs, glossy, and of a 
very dark-brown hue, that of the branchial opercula being dull-yellow. 
In May, 1838, an adult male of this species was found under a stone in a moist pasture 
at Oakland.
