Vertebral Column.^ 



The following Table gives the number of vertebrae in each 

 region, with the length of each region and other measurements, 

 in Megaptera, and, for comparison with it, in B. musculus and 

 in B. borealis : — 



TABLE I. 



1 In making the following observations on the vertebral column of Megaptera, 

 those of B. musculus and B. borealis were placed beside it for comparison. In 

 this way an appreciation of its distinctive characters could be made. With this 

 view a comparison is given with the corresponding parts in B. musculus, in so
