Skeleton. 
The cranium, viewed from above, was considerably flattened ; its shape was somewhat 
that of an elongated isosceles triangle, having its apex at the extremity of the inter- 
maxillary bones, and its base corresponding to a line drawn from the anterior border of 
one glenoid process to that of the other ; its length was a little more than twice its 
breadth, and its component segments, with the exceptions of the petrous and tympanic, 
were extremely soft and spongy in structure. 
The occipital bone was made up of the combined interparietal, supraoccipital, exoc- 
cipital, and basioccipital elements; it was the largest of all the cranial bones, and 
consisted, first, of a broadly expanded superior portion, irregularly triangular in outline, 
which formed almost the entire roof of the skull ; its somewhat rounded apex extended 
forwards to articulate with the posterior edge of the frontal : the external margins over- 
lapped those of the parietals and frontals, and the basal line, which extended from the 
extremity of one exoccipital to that of its fellow of the opposite side, formed the poste- 
rior boundary of the cranium ; this margin was irregular in outline and lay on a plane 
posterior to the foramen magnum, which latter was situated at the junction of the 
basilar and calvarial portions ; it was oval in shape, and measured If inch in its vertical 
by 2^ inches in its transverse diameter ; it was bounded laterally by the condyles, which 
approximated inferiorly, where they were separated only by a sulcus whose breadth 
varied from half an inch at its widest, to one-eighth of an inch at its inferior and nar- 
rowest part. The condyles were ovoid in shape, and extended backwards and outwards ; 
their superior rounded extremities formed the boundaries to the inferior and lateral 
halves of the foramen magnum, and were thickly covered with incrusting cartilage, but
