processes of the anterior dorsal vertebrae, which, in their turn, 

 continue backwards the upper series of cervical transverse 

 processes. 



In the Physeteridce (comprising Physeter, Hyperoodon, 

 Ziphins, and the allied forms) a very different and peculiar 

 arrangement occurs (Fig. 21). The transverse processes in 

 the anterior thoracic region (/) are placed quite similarly to

those of the ordinary Dolphins ; but passing backwards, 

 instead of changing their position on the vertebrae, they 

 gradually become smaller, and finally disappear: while, 

 simultaneously with their diminution in size, other processes 

 (/') rise from the body of the vertebra, in the situation of the 

 capitular attachment of the rib, which, rapidly increasing in 

 length, become continuous serially with the lumbar transverse
