KNOX ON THE CETACEA. 71 



It appears from my notes, that at that time M. Gr. Cuvier 

 considered the species I now describe as identical with the Great 

 Rorqual I had described about two years previously ; but I felt 

 convinced then, as now, that they form distinct species, and in 

 this opinion some continental anatomists seem to coincide. 



Being persuaded that there was some inaccuracy in former 

 drawings of the species, I had the specimen suspended and drawn 

 with great care by Mr. Edward Eorbes. This position explained 

 the mechanism of the mouth, showing its great size, even in the 

 short Balsena Whales ; its great capacity in the Mysticetus had 

 never been doubted. 



As to the species, the conclusion I arrived at was, that the 

 specimen belonged to that termed by Fabricius rostrata, and 

 that individuals of the species had been seen by John Hunter, 

 Sir James Watson, and Fabricius.
