The skeleton in Mus. Hull. Cervical vertebre : first and second ~ 
separate, large; rest very thin, separate, rudimentary. Skull: 
length, entire, 19 inches, of beak, 84 ; breadth at notch, 7 inches. 
Scor esby gives a very good account of this animal (Arct. Reg. 
1.151). The best Agu are those of Scoresby, t. 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. Duhamel’s Pech. iii. t. 26. | 
f. J, 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. | 
PO. Narwalus Andersonianus, Lacep. Cetac.163, from Antero so 
Iceland, 225, described from the same specimen as Mr. Brag 
drew, is figured by Lacep. t. 4. f. 2.
