joint, where it begins tapering gradually to the tip of the claw. Practi- 
cally smooth except for a few very small bristles on the outer side of the 
third joint. When not carrying eggs, the appendages commonly extend 
outward and a little backward, then curve forward and in again toward 
the middle line. The bending occurs particularly at the fourth and at 
the eighth and ninth joints. 
Eggs small, carried on the ovigera in one (pl. x1v, fig. 15) or two (fig. 14) 
large, wrinkled, cake-like masses, occupying the whole space under the 
animal and extending so far that when looked at from below only the 
legs from the fourth joint outward are visible, except the posterior pair, 
which can usually be seen because the eggs are carried well forward. 
Legs stout: ¢c.1 broader than the lateral processes of the segments, 
with the appearance of a dorsal notch on its outer border due to the 
close approximation of two dorsal tubercles; ¢.2 rather smaller than ¢.1 ; 
¢.3 rather smaller than ¢c.2; the 3 joints together in the third leg about as 
long as the proboscis ; f/ strongly developed, about two thirds as long as the 
coxal region; proximal half of the ventral surface considerably swollen (in 
male as well as female), a rather weak dorsal tubercle at the distal 
extremity; 71 about equal to f, but more slender; #2 rather shorter than 
#1; ¢s.1 very short, subtriangular; ¢s.2 about as long as 742; c/. less 
than half as long as ¢s.2, rather strongly curved. On the dorsal surface 
of f., and of ¢.1 and #2, near their distal ends, there is a single compara- 
tively strong spine; ventral side of 42 beset with smaller spines at its 
distal end, while the tarsal joints, especially the first, have their ventral 
surfaces thickly beset with these short spines. 
The 11 females measured range from 4 mm. to 8 mm.; the males 
average somewhat smaller, the largest being but 6.3 mm. in length.
