ESCHRICHT ON THE 



specimen, it has only a length of 12^"; the former is, therefore, almost twice as long as the 

 latter, though the whole skeleton can hardly he supposed to have been more than one sixth 

 longer. The bones of the arms are much thicker, though not perceptibly longer, the cranium both 

 longerand broader; the vomer does not appear on the palate; the teeth are compressed from the 

 sides and not worn at all at the points ; even in the largest of these crania having a length 

 of 40", and a breadth of 26", in which the midmost teeth are long and almost entirely closed at 

 the roots, they only present a lengthened worn surface on either side. 



2. The length of the largest of the skeletons must be estimated at about twenty-three feet. 

 Of this specimen, six vertebrae of the dorsal and lumbar regions and the last ten caudal vertebrae 

 are wanting besides the cranium, supposing that the total number of the vertebrae was exactly 

 fifty-three, as in the small skeleton. The estimate has been made by comparing the vertebrae and 

 continuous portions of the spine, as we found them, partly with the corresponding ones of the 

 small skeleton, by which comparison they proved to be about twice as long as those of the latter, 

 and partly with those of the Benzon specimen, than which they appeared about one sixth longer. 

 The length of the largest skeleton but one I think I may estimate at^ , that of 



the smallest but one at times longer than that of the very young one (11' 9"), the length 



of the former accordingly at , that of the latter at . But the crania do not 



increase in the same proportion. 



The figures A, B, and C, represent the hindmost tooth but four of the left lower jaw of 

 different specimens of Orca, with their transverse sections, at one half their natural size.

C. Of the smallest specimen but one from the Faroe Islands. 



D. The pelvic bones of the largest specimen but one from the Faroe Islands. 



P.S. Mr. Miiller, who sent the skeletons and crania of this new species from the Faroe 

 Islands, states that the animals from which they were taken belonged to a small shoal
