MEMOIRS OF THE CARNEGIE MUSEUM 
In Cynodesmus brachypus the pelvis is practically complete and again displays 
f { Pp 5 i 
characters which are entirely unlike those in Daphenodon and are more like those in 
the recent canids. 
The ilium, while not as much expanded at the supra-iliac border 
° 
as in Canis, has a tendency to become more generally concave on the external face, 
the attachment for the sacrum is more anterior, and the ischium and pubes are 
decidedly shorter than in the genus under description.

MEASUREMENTS OF PELVIS.

by surface fragments which may or may not belong 
to this individual. The younger specimen (No. 
1589a) which was found with the type has the 
shafts of both femora with the proximal ends lost 
and the distal ends slipped off at the epiphysial su- 
tures (see fig. 42). A third and larger specimen, 
which belongs to Amherst College, has the femur 
well preserved. This complete femur will here be 
used in connection with the description of the type 
and the material of the younger individual in the 
Carnegie Museum (see Pl. LXX XI, figs. 1 and 2). 
The length of the femur cannot be accurately 
ascertained, but I judge that it is approximately 
equal to that in an adult specimen of Canis lupus. 
The head is rather small and hemispherical, and the 
neck is moderately long. The pit for the ligamentum 
teres is deep and located on the posterior half of 
the head nearer the inferior than the superior bor- 
der. When the bone is held in position the head 
is directed upward and inward in approximately 
the same proportion as is the case in the recent 
dogs, and as is also the case in Daphenus. The 
transverse bridge from the head to the great tro- 
chanter is quite heavy on its posterior face, which causes the digital fossa to
