Type. $ and ? , University of California, No. 19,514, San Diego, Cal- 

 ifornia. 



Trunk rather slender, cylindrical, tapering posteriorly ; lateral processes 

 long, well separated, larger distally, where each has a small conical pro- 

 jection on the dorsal side and pointing somewhat outward. First trunk 

 segment rather larger than the 2 following segments together ; constricted 

 in its anterior half and produced forward into a long narrow neck. 



Caudal segment moderately long (nearly one and a half times second 

 trunk segment) ; projecting upward at a sharp angle ; approximately 

 cylindrical, tapering to a point, often bulging somewhat in the middle, 

 notched at tip ; may be armed with i to 2 or 3 hairs on each side. 



Eye tubercle placed at extreme forward end of first trunk segment 

 and projecting upward and a little forward; about as long as second 

 trunk segment, cylindrical. Viewed from the side it rounds evenly to a 

 blunt point; viewed anteriorly or posteriorly it is seen to have a project- 

 ing angle on each side at the point of narrowing. Eyes nearer the top 

 of the tubercle than the base; the anterior pair somewhat larger and a 

 little lower than the posterior. 



Proboscis about as long as first trunk segment, from the posterior part 

 of which it issues ventrally and projects obliquely downward and forward ; 

 basal portion of slightly smaller diameter than the distal ; truncate. 



Chelifori extending forward from the extreme end of the first trunk 

 segment, which furnishes but a slight projection beyond the eye tuber- 

 cle for their attachment; about equal in length to the segment to 

 which they are attached. Scape slender, nearly cylindrical, only slightly 

 enlarged at distal end; smooth except for a few small hairs. Chela 

 pendant, bent at nearly a right angle to the scape and hardly half as long, 

 sparingly beset with hairs ; fingers slender, curved, sharply pointed, about 

 as long as palm ; movable finger longer and more strongly curved. 



Ovigera long (as long as, or longer than, animal), slender. First joint 

 short and comparatively thick; / 2 over twice as long and more slender; 

 these 2 joints extend downward from their attachment to the first trunk 

 segment. The third joint bends backward, running nearly parallel with 

 the trunk; it is half again as long as the first two joints taken together 

 and even more slender than the second ; slightly curved, with the con- 

 vexity upward ; about one fourth of its length from the proximal end is 

 a constriction which on superficial examination might be taken for an
