intermaxillary bones contract in the middle, and then continue of 

 the same width in front. The hinder part of the jaw-bones is nearly 

 perpendicular, and the .temporal bones are broad and erect. — Guv. 

 Oss. Foss. V. t. 25. f. 5-7. 



The foetal skuU is shorter, lower, and the hinder part of the jaw- 

 bone is more slanting. — Cuv. Oss. Foss. v. t. 25. f. 1-3. 



Cervical vertebrse all (1-7) anchylosed by the neural arches into 

 one crest. — Guv. Oss. Foss. v. 378. 



The baleen is about 6 feet long, elongate triangular, rather rapidly 

 tapering to a fine point. The internal fibres are rather coarse, but 

 much finer than in B. Japonica.

The atlas, axis, and five cervical vertebrse are united into one by 

 their bodies, and all the spinous processes are soldered into one crest. 



Eibs 15 . 15 ; the last four and the first two do not attain the body 

 of the vertebrse, and are not attached to the transverse apophyses. 



The first pair is flat and very broad, especially at the sternal end. 

 The last three are slender and short. Vertebrse 49, viz. nuchal 7, 

 dorsal 15, lumbar and caudal 27. The chevron bones commence on 

 the eleventh and twelfth, and end at the twenty-sixth. The spinous 

 processes form a nearly uniform series, inclined forwards. The 

 thumb has two, the index four, the middle finger five, the ring 

 finger four, and the little finger three joints, all ending in a carti- 

 laginous dilatation. — Otw. Oss. Foss. v. 379. 



The tympanic bone is suboubical and rugose; the back is much 

 swollen; the inner edge is protuberant, and forms an angle with 

 the surface nearer the outer margin; the upper portion is pro- 

 minent and snbangular, and separated from the lower portion by 

 two irregular depressions ; the hinder margin is thick, convex, and 

 rounded ; the lower surface is rather flattened, with an irregular-
