The skeleton of this specimen is preserved in the Bristol In- 

 stitution. 



The skeleton in Mus. Roy. Institution, Liverpool, has the skull 

 60 inches long, 18 inches from top of crest to palate ; the inter- 

 maxillaries are convex, and distinctly to be seen to the front of 

 the blowers ; orbital crest erect, scarcely as high as the process at 

 the back of the blower ; the nuchal vertebrae anchylosed, the three 

 first into one mass, with a long conical lateral process ; the dorsal 

 process of the two hinder separate. 



3. HYPEROODON DOUMETII. The CORSICAN HYPEROODON. 



Jaws paved with acute tubercles ; dorsal f the length from the 

 tip of the jaws : blowers lunate, with the convexity in front. 



Hyperoodon, Doumet, Bui Soc. Cuvier. 1842, 207. t. 1. f. 2. 

 Inhab. Corsica. 



" Jaws toothless, but paved with small, long and acute tuber- 

 cular granulations; lower jaw with two rather longish, acute, 

 slightly arched and longitudinally grooved teeth in front ; larynx 

 with a kind of funnel at the base of the tongue, like the beak of 

 a duck, or rather of a spoonbill, 5f inches long ; gape small ; beak 

 conical; eyes small, near middle of head; blowers lunate, with 

 the points directed backwards; pectoral fin 19 inches long, 6f 

 wide; dorsal nearly 8 inches high, 49 inches from the tail; the 

 tail is broad, lobes equal." Doumet. 



According to this description the dorsal fin of this species must 

 be further back than in any other of the genus, and the pavement 

 of the jaws is quite peculiar. It agrees with Dale and Baussard's 

 descriptions in the form of the blower, but differs from them in 

 the position of the dorsal.
