There are four well-developed metacarpals, of which the 
external one articulates with the ulnar centrale, while the 
others are borne by the distal carpalia. 
The) fourdigits /are) made) up jon) 23.25) 3) wands) senaioine 
phalanges. The terminal phalanges taper to rounded ends. 
The ilia are very slender. They measure 9.5 mm. long, 
.7 mm. wide and .5 mm. thick. The posterior end of the ilium 
is much enlarged, and forms about the anterior upper half of 
the acetabulum, the remainder being supplied by the ischium. 
The acetabulum is not completely closed. At the interior and 
ventral aspect of the pelvis, at the lower margin of the sutures 
between the ilia and ischia, are two thin plates of calcified 
cartilage about 1.5 mm. in diameter, which probably represent 
the pubes. 
The femur is very slender. Its length is 15 mm., and its 
least diameter is 1 mm. It bears a strong proximal keel. 
The tibio-fibula is 16.5 mm. long by .9 mm. in diameter near 
its center, but broadens at the ends to 2.4 mm. 
The tarsus is formed of the usual proximal and distal por- 
tions. The former comprises the astragalus and calcaneum, 
about 9 mm. long, which are fused for a distance of 2 mm. 
proximally and 1 mm. distally. These bones are quite slender. 
The more distal tarsal bones are four in number—one at the 
end of the astragalus, one bearing the same relation to the 
calcaneum, a smaller one between these, and a still smaller 
one at the base of the first metatarsal. 
There are five metatarsals corresponding to the five toes. 
Beginning with the inner one, the toes are composed of 2, 
2, 3, 4, and 3 straight, somewhat tapering phalanges. 
: 
The hyoid is well developed, has long anterior processes, 
and is shaped as shown in the accompanying cut. 
The alimentary canal of this specimen contained a small 
bright red spider and the remains of two beetles of different 
species.
