Cervical and part of dorsal vertcbrrc and the baleen in the British 

 Museum. Le!i{2;th 50 feet. 



I'hc ujiper 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, aboiit one-fourth 

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

 slenderness and form of the lateral processes of the cervical vertebra; 

 seem to separate this species from P. anfiquot-imi, 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 vertebra) are 

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