which respect B. laticeps approaches it nearest, may lead one to suppose that it, like this, had 

 a skull of an elongate conical form, with a base not much wider than the facial part or beak, and 



also with a large, wide beak, and very short baleen. The lower jawbones (fig. 1) are rather 

 strongly compressed, as in B. laticeps ; they are, when seen from the side, but slightly tapering 

 at the fore end, and the hinder end at the condyle and angle is very high, considerably higher 

 than the height of the bone at the processus coronoideus, and with the angular part projecting 

 behind the condyle. 



The cervical vertebrae are separate, and the processus transversi do not form rings on any of 

 the four that were found ; but they have, except the atlas, rather long lateral processes, and these 

 have their points not very far separate. The atlas (fig. 2) is large and thick, and has short lateral 

 processes, the height of which is greater than their length. It has both tuberculum atlantis 

 posticum and anticum, and its foramen spinale is sharply pointed downwards. The articular 

 surfaces for condyli occipitales extend upwards about equally with processus transversi, and are 

 separate below. The hinder articular surfaces are lower, and are united below. It has altogether 



the character of the atlas of a Balænoptera or Meffoptera, and seems, in regard to the form of the 

 lateral processes, to approach nearest that of B. laticeps, although these processes are less com- 

 pressed than in the latter. 



The lower ramus (parapophysis-) of the lateral process of the 3rd cervical vertebra (fig. 3) 

 is larger than that of the other three hinder cervical vertebræ that were found, and is neai'ly 3" 

 high, and much larger than the upper ramus. The latter has a short process at the point, which is 

 directed downwards towards the point of the lower ramus, which is bent upwards. The lateral 

 processes of this, as well as of the 4th cervical vertebra, ai'e directed somewhat backwards. The 

 lateral processes of the supposed 6th cervical vertebra are directed a little forward, and under the
