the eye prominence; appendages all of uniform reddish (ochre yellow;
fingers of mandibles reddish brown, with black points, and teeth blunt.
Lengths, maxillary palpus twenty-three mm.; labial palpus, eighteen mm.;
first legs eighteen mm.; second legs twenty-two mm.; third legs thirty
mm.; jaw tip to anus, thirty-three mm.; eyes to anus, twenty-five mm. :
terminal joint of palpus continuous; tarsus apparently one jointed;
head, seven mm. broad; five mm. long, with faintest possible trace of
median striae; anterior border straight, oblique at angles, rounded at
sides; broadly truncated behind; hairs very sparse, fine and short; eye
prominence
of medium size, slightly elevated, and
slightly projecting, black in front and at the sides, pale behind, a few
fine unequal hairs; eyes bluish, their interval greater than their
diameter. Mandible, nine mm. long; base five and half mm. long; strongly
convex; swollen at their base; furnished with fine spiny hairs; rather
sparse and unequal; three obscure dorsal longitudinal bands on the base
of each; teeth obtuse, two of medium size, fol1owed by one, rather large
one, then a very small denticle, then the largest tooth of all, then two
minute denticles; teeth then divide into two series, the outer with
three teeth- the last smallest; the inner series with four teeth, the

the lower finger is a little shorter than the upper, and has two large
teeth; the interior being largest, and with a small denticle on its
anterior margin; the lower finger with a distinct lateral carina
extending nearly to the point; brushes to the fingers as in the other
♀
Datames. Maxillary palpus; femur with a number of spiny hairs on
the inside, especially on the ultimate portion; tibia and metatarsus
also with a few irregular spiny hairs on the inside; more slender than
those' on the femur; thickly clothed, especially on outside, with fine,
short hairs, with a few very long
ones
intermingled; length, femur.
six mm.; tibia six and a half mm.; metatarsus, five mm.; tarsus, one and
a half mm., each enlarged from base to extremity; metarsus, and tarsus
closely and rigidly united, but separation
distinct; tarsus with numerous fine hairs. First legs slender, with fine
hairs, without spines, without claws. Second legs, metatarsus, with six
spines one side, four the other; tibia with two spines near the end,
several weaker ones toward the base. Third legs, metatarsus with five
pairs dorsal spines; three ventral spines; tibia, with few weak spines.
Fourth legs, metatarsus, with row of about nine spiny hairs on
underside, besides the three regular spines; no spines on back; tarsus
long, single joint with about four pairs of spines beneath; all the legs
furnished with numerous fine hairs, some of them very long; tibia I, II,
Ill, with terminal spine. Head and abdomen almost without hairs; first
sub-abdominal segment with
sub-triangular plate
divided into two lobes by a longitudinal depression, which enlarges at
