Vertebrae.—There are four coalesced cervical vertebrae. 
In the atlas the foramina in the arch for the exit of the first 
pair of spinal nerves are complete on each side ; the inferior 
lateral processes are thick and strong and slightly bent 
backwards, the maximum diameter between them being 
250 mm. 
There are seven thoracic vertebrae, probably being the 
2nd, 3rd, 4th, 5th, 7th, 8th and 9th. The last three have facets 
for the articulation of ribs on the transverse processes only. 
There are fourteen post-thoracic vertebrae, four of 
which are caudal centra only. Four incomplete ribs, one 
chevron bone and five epiphyseal dises are present. 
Three vertebrae of a dugong and the coracoid of a 
turtle were forwarded at the same time, and testify to the 
efforts of the donor to secure as many bones as the cireum- 
stances permitted.
