M - ischiofemoralis .—The belly was somewh 
larger and deeper, corresponding with the slight 
broader and more deeply cupped ischium; tend, 
ot insertion broader and stronger than in VC or H, 
M. flexor cruris media Us .—This had been ci 
away from the origin in skinning. It was similar i 
VC but perhaps slightly more robust. 
M. pubischiofemoralis .—The pars caudalis was 
similar to HS, whereas in VC the origin was less 
discrete and lay partially under the posterior part 
ol pars cranialis. The pars cranialis was similar to 
the other species. 
M. obturalorius lateralis .—Both pars dorsalis 
and pars ventral is were present, as noted by 
Raikow (1976:783). These were larger and better 
developed than in VC or HS. 
M. obturalorius medialis .—This appeared to be 
slightly larger than in VC. 
M. iliofemoral is interims.— There were no 
detectable differences in this small muscle.
