in length to the tibia and a little longer than the distance from the

quite twice as long as the tarsus. Metatarsi I and IT scopulate 
distally for about 4 of their length. Tarsus I unspined, II with 
4 small outer spines, III with several internal and a number of 
external spines, some of the latter stouter, IV with a distal group 
of small spines internally and a double series of longer spmes 
externally. Metatarsus I with 1 inner and 2 outer apical spines and 
an outer row of 2 other spines below, the inner surface also with a 
stout spine near. the base; II with 2-3 apical and 3 other stout 
spines at or near the outer inferior margin, 1 apical inner spine and 
with or without another inferior and a superior inner spine; III 
numerously spined on all sides; IV numerously spined below, with 
arow of 3 spines along the inner upper edge. Tibia I with 9-10 
strong spines along the inner surface, including a distal pair, and a 
row of 6-8 similar spines along the outer inferior edge, II with long 
spines below and 3 spines along the inner upper edge, III spined on 
all the surfaces, the anterior surface with a broad band of about a 
dozen short spines, IV with 3 apical spines and several pairs of long 
setiform spines below, the inner surface with about 4 spines above. 
Patellze I and II with an apical spine below, I also with 3 and I] with 
2 spines along upper inner edge, III with numerous short spines on 
the anterior surface and a row of 3 stout spines on the dorsal 
surface, IV with a stout apical spine below. Femora with several 
rows of spines above, IV with a distal group of short stout spines at 
upper outer edge. All the claws with a double series of teeth below, 
the anterior claws with about 6-8 teeth in a row, those of fourth leg 
with 4-6 teeth in each row. 
Abdomen spined near the base above. 
Posterior spinners with the apical segment apparently a little 
longer, or at least not shorter, than the penultimate segment (seen 
from below). 
Posterior sternal sagilla moderately large, their distance apart 
scarcely exceeding their length but distinctly exceeding their distance 
from the lateral margin. 
Measurements.—Total length 14; length of carapace 53, width 44;
