some short pieces of " Southern Whale-fin," probably forming 

 the end part of a side, at the inner, or shorter or palatine edge of 

 each blade, two or three small separate linear processes of whale- 

 bone ending a parcel of hairs similar to the pieces and form above 

 described, but of a smaller size and rather more wavy. Scoresby, 

 who gives a very detailed account of the position of the baleen in 

 Greenland whales (Arct. Reg. i. 457, and ii. 415), does not men- 

 tion anything of the kind in that animal ; but it is described as 

 occurring in the Fin Back by Mr. F. Knox see Cat. Anat. Prep.

 Inhab. Japan, visiting the coast periodically. The head is often 



covered with barnacles. 



This species is only described from a model, made in porcelain 

 clay by a Japanese, under the inspection of a Japanese whaler 

 and M. Siebold ; but no remains of the animal were brought to 

 Europe. The figures in the Fauna Japonica are from this 

 model. 



B. Japonica and B. lunulata, Lacep., are from Chinese drawings.

The baleen is nearly as long as the Greenland, varying from 

 7 to 12 feet long, and is slender ; but for the same length it is 

 nearly twice as thick in the substance, and it gradually diminishes 

 in thickness towards the ends. The enamel, when the outer coat 

 is removed, is not so polished as that of the Greenland, and when 

 cut through, the centre fibres are thicker, tubular, and occupy
