bones already described, and there is no evidence whether its proximal end received 
the radius in the same way in a groove as in the bones presently to be described. 
The hand is folded back so as to expose the inferior aspect of part of the carpns, 
the ineta-carpns, and the five digits. The width at the carpus is fully 4 centims . and 
the length of the meta-carpus and phalanges is 5 centims. The entire length of the 
fore-limb is about 18 centims. 
The distal row of the carpns appears to include four bones. 
The meta-carpal bones become more elongated from the first to the fourth, and the 
fifth is only a little shorter. At the same time the middle of the shaft, which at first 
is scarcely defined, gradually becomes slender, though the terminal ends, and especially 
the distal ends, do not become narrower. The first meta-carpal is 9 millims. long, and 
nearly quadrate ; i he fourth is 3 centims. long. Tn the first digit there are two 
phalanges, in the others three phalanges. These bones are short and broad, well 
ossified, with well defined articular ends and lateral constrictions, but the terminal 
conical claw phalange is relatively large, and in the middle digit, in which it is longest, 
measures 1'6 centim., and in every digit it is longer than any other phalange. The 
claws curve a little downward, are rather flattened on the under side in front, and 
compressed behind. 
The specimen may be named Earycarpus Oiveni. 
Femur Titanosuchus ferox (Owen). (Plate 19.) 
The limb bones which are marked in the British Museum Register as associated 
with the skull fragments named by Sir B. Owen Titanosuchiis ferox, comprise, besides 
smaller pieces, a femur and a humerus. The remains of the femur have been put 
together by the British Museum masons with great skill, and I have no doubt their 
restoration exhibits accurately the complete form of an Anomodont femur more perfect 
than that attributed to Dicynodon leoniceps. The specimen is numbered 49,368. It 
is a straight stout bone, flattened in the vertical oPantero-posterior direction, and only 
moderately exp^mded at the extremities, as compared with the humeri of Dicynodon. 
Its extreme length from the articular head to the outer condyle is 615 centims. The 
shaft is most constricted in its lower third, and the proximal end is more expanded 
transversely than the distal end, and twisted a little inward so as to be inclined to it 
at a slio’ht anMe.

The inferior aspect of the bone is flattened, but for the development of the condyles 
at the distal end. The transverse width over the condyles exceeds 20 centims. The 
rounded convexities of the inferior surface are worn away. The inner or tibial condyle 
had a vertical extent of 14 centims., and a transverse width in the middle of about 
8 centims. The fibular condyle is developed so as to extend 2'5 centims. distally beyond 
the other condyle. The posterior surface of tins condyle has a vertical measurement 
at 11 centims., and a transverse measurement of about 9 centims. The inter-condylar
