The seven cervical vertebrae are united — the posterior four in the lower j)art 

 of their centra only. 



Above the only ones which are united, and thus form a solid crest, are the 

 first six — the seventh or last being entirely separated from the others in every 

 part except the lower centrum. 



On the right side the diapcpliyses of the third, fourth, fifth, and sixth are all 

 united, the first a:i.d seventh being separate. 



On the left side, the fourth, fif ih and sixth are united, the others being sep- 

 arate. The second, third and fourth alone have inferior transverse processes. 



The first rib has but one articulating surface, which joins to the transverse 

 process of the first thoracic vertebra. The next eight ribs are joined to the 

 vertebrae by two articulating surfaces, one j unction being to the transverse pro- 

 cesses and the other to the bodies of the vertebras. The remaining five, float- 

 ing ribs, have only one attachment, which is to the bodies of the vertebrae. 



During the removal of the various bones from the spot where the carcase had 

 been stranded after the exhibition was over to a place of greater safety, I close- 

 ly inspected all the work, so that nothing should be left behind. The only 

 bones which are therefore missing and were probably lost are two from the 

 three composing the rudimentary pelvis. I was particularly careful when the 

 bones of the anterior limbs were being removed and had them macerated sepa- 

 rately. If the results are the same in other whales of the same age, it must be 

 taken as conclusive that the carpal bones are developed only when the animal 

 is approaching adult years, for there were none in this specimen and but few 

 phalanges. 



It appears that this whale belongs to the species which was formerly some- 

 what abundant off the Atlantic coast of North America, and was the one that
