the surface on each of the paired bones which formed the acetabulum, but no femur 
had been preserved (fig. 23, C). 
Gasco, in his memoir on the Taranto whale, figured the concave surface of one of 
the pelvic bones and showed the articular area for the femur, though that bone had not 
been preserved. GuLDBERG, in his memoir on the Nordeaper, gave three figures of a 
pelvic bone which generally resembled those above described. He was, however, so 
fortunate as to obtain a specimen in which the rudimentary femur was in articulation 
with the os pelvis and the capsular ligament of the joint was in place. Further, the

cartilaginous tibia was also present and the articular surface at the lower end of the 
femur for the tibia was visible. 
ReINHARDT in 1843 was the first to recognise the rudimentary femur and tibia in a 
new-born Right Whale, Balena mysticetus, and some years later Escuricut and he 
observed them in a half-grown and in a full-grown specimen. The most complete 
description of the os pelvis and rudimentary hind limb in this whale was given by 
Sir Jonn SrrurHers,* from its examination in five animals. In their general form 
the pelvic bones in 6. mysticetus resembled those in biscayensis, though they were 
somewhat stronger in the former species. From his description and illustrative figures, 
the ventral process at its lower end (o in SrrutHERs’s figures) was for the attachment of 
the interpelvic ligament connecting the two bones ventrally, as well as for that of the
