CETACEA. 15 



a, 6, c. Three plates of baleen. Length, 20 inches ; width at 

 the base, 2 inches 6 lines. Western Australia. Presented by 

 J. Warwick, Esq. 



The specimens figured in the ' Voyage of the Erebus and 

 Terror,' tab. 1. fig. 1. 



This species is only known from three laminae of baleen. It is 

 so much smaller and broader, compared with its width at the 

 base, and so differently coloured from the baleen of any of the 

 other species, that I feel justified in considering it as distinct. 



tt Baleen thick, rather brittle ; enamel thin, internal fibres 

 numerous, thick, rather intertwined, forming a thick rigid 

 fringe. 



3. BAL^SNA AUSTRALIS. The CAPE WHALE. 



Uniform black. Skull convex. The nose of the skull high, 

 straight, and rather suddenly bent down in front ; the nose and the 

 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. Cuv. Oss. Foss. v. t. 25. f. 5-7. 



The foetal skull is shorter, lower, and the hinder part of the 

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



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 the former.
