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 1 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; 7.2 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
