The Cervical Vertebre exhibit in a very marked degree the antero-posterior compres- 
sion so characteristic of the Cetacean neck. ‘The length of the bodies of the seven 
vertebre of this region taken together, when compared with their own width, or with 
the length of the whole vertebral column, appears to be less than in any other 
Mammal. 
The atlas is distinct from the other vertebra ; the remaining six are united by their 
bodies and spines into one consolidated mass, which, in the case of the Tasmanian 
specimen, is further united with the body of the first dorsal vertebra. This disposition 
of the cervical vertebra (the distinctness of the atlas and union of the posterior six) 
appears to be the rule in all Cachalots’ skeletons, although unknown among other Ceta- 
ceans. In the most nearly allied forms, Kogia, Hyperoodon, and Micropteron, they are 
all united into one solid mass, as in Balena among the true Whales. In Platanista, 
* The vertebra in this region, as is usually the case in Cetacean skeletons, contain much more oil than at 
other parts, which partially accounts for their great weight. Elsewhere the vertebre were free from oil, and 
dry at the time they were weighed. 
+ Processes so much injured that accurate measurements cannot be made.
