CATALOGUE OF THE CETACEA. 295 
Species incertce sedis. 
The following species are known only from drawings, or very insufficient materials; most of 
them (unless we except those of Mr. Peale, whose delineations have proved in at least one case 
to be remarkably accurate) can hardly hope for identification, and it is very probable that many 
of them are identical with species described from skulls only. It is of course impossible to 
determine the genus of any of them; and it would be a relief, if they, together with the species 
erected on aboriginal pottery and carvings, and drawings of Chinese and Japanese artists (!), could 
be wiped away from our books altogether.
