c. Skull, female, not in a good state. 



The following is the measurement, 1st, of a skull in the Col- 

 lege of Surgeons, and 2nd, the female skull c. in the British Mu- 

 seum, in inches and lines. 



Skull : length, entire 21 '6 2O6 



length of nose 9'9 9'3 



width of orbit 14'6 14'0 



width of notch 8'0 7*9 



width of intermaxillaries . 3*0 3' 6 



The skeleton in Mus. Hull. Cervical vertebrae : first and second 

 separate, large ; rest very thin, separate, rudimentary. Skull : 

 length, entire, 19 inches, of beak, 8 ; breadth at notch, 7 inches. 



Scoresby gives a very good account of this animal ( Arct. Reg. 

 i. 131). The best figures are those of Scoresby, 1. 15, then Sower- 

 by, Brit. Misc. t. ; but this has a second horn erroneously 

 added, which was not in the original drawing. Bonnaterre's 

 figure is far too ventricose ; it has been copied by Lacep. t. 4. 

 f. 3, Blumenbach, t. 44, and others. DuhameVs Peek. iii. t. 26. 

 f. 1, is, on the other hand, too slender, and with too small a head. 



1. Narwalus microcephalus, Lacep. t. 5. f. 2, from a drawing 

 of Mr. W. Brand, appears to be only a bad representation of this 

 species. 



2. Narwalus Andersonianus, Lacep. Cetac.163, from Anderson, 

 Iceland, 225, described from the same specimen as Mr. Brand 

 drew, is figured by Lacep. t. 4. f. 2.
