Joints 3 to 8 are provided, mostly on the outer curve, with rather long, 
closely set bristles, which tend to turn backward for the most part, ex- 
cept on 7.3. 
Eggs carried by the male in numerous small pear-shaped masses, 
which are attached to the ovigera by short thread-like stalks. One male 
may carry between 30 and 4o of these masses, in each of which there 
are relatively few eggs. 
Legs about twice as long as body: ¢.1 short, square, provided on the 
dorsodistal border with a strong median protuberance which has on each 
side of it a smaller projection bearing a few short bristles and forming the 
outer corners of the joint (pl. x1x, fig. 2); ¢.2 nearly twice as long as¢.1, 
bearing in the male on the third and fourth legs, in the usual position, a 
long thumb-like genital projection, about half as long as the joint from 
which it arises, considerably broader distally than proximally, and rather 
thickly beset with long slender bristles; ¢.3 shorter again. Femoral joint 
about equal to coxal region, of the usual shape, much broader in the female 
and with a rounded protuberance distally on the dorsal edge; 41 and 42 
about equal to each other and to f in length, but of smaller diameter 
than the last; ¢s.1 small, triangular, rounded below; 4s.2 stout, over half 
as long as 4.2, rather strongly arcuate; heel hardly differentiated, but 
there are 3 rather strong, distally curved spines at this point; sole 
armed with comparatively long, thickly set bristles which extend back 
on to the heel (fig. 5). Claw about half as long as ¢s.2, but slightly 
curved; aux. c/. well developed, half aslong asc. All the joints beyond 
¢.1 beset with more or less scattered short bristles; these are consider- 
ably longer and thickly crowded on the ventral side of ¢3 and the 
proximal end of f. 
Length 6 mm. to 7 mm., extent fully 30 mm.; the two sexes about 
the same size. 
Color in alcohol yellow to dark brown. Integument thick; cuticular 
cavities large and numerous. 
Immature specimen.—There was with Lot 2 one immature specimen, 
about two thirds the size of the adult animals, and with chelate chelifori; 
the chelz rather stout and strongly forcipate (fig. 3). The ovigera were 
small and undeveloped.
