Cervical and part of dorsal vertebrae and tte baleen in the British 

 Museum. Length 50 feet. 



The upper lateral processes of the third, fourth, and fifth cervical 

 vertebrae are very slender and bent down, with two slight angular 

 ridges on the outer edge ; the lower processes are much thicker and 

 bent up at the end, with a broad flat lower edge near the base, which 

 forms an angle at the end. The bodies of the cervical vertebrae are 

 roundish oblong, rather wider below than above, about one-fourth 

 the width wider than they are high. The form of the body and the 

 slenderness and form of the latered processes of the cervical vertebrae 

 seem to separate this species from P. antiquorum, as well as the 

 separate form of the lateral processes. In the Plymouth specimen 

 of the latter in the Museum, the bodies of the cervical vertebrae are 

 oblong, transverse, being one-third the width broader than high.
