io MAMMALIA. 



Sub-fam. ZIPHIIN^E. 



42. Hyperoodon rostratum (Chemnitz), Common Beaked- 



Whale. 



Casual visitant, of rare occurrence. A female was stranded in 

 the Humber, close to Hull, in 1837, the skeleton of which 

 is now in the Hull Museum (Gray, Cat. of Seals and 

 Whales, 1866, p. 331 : cf. Zool., 1849, pp. 2409, 2441). 

 Another specimen, stranded in Patrington Haven, was seen 

 by Dr. Foster, by whom the skeleton was articulated. 

 (Howarth, Nat, 1880, vol. vi., p. 26). 



43. Hyperoodon latifrons Gray. Broad-fronted Beaked- 



Whale. 



A skull, dredged up by a smack on the Great Fisher Bank, 

 on March 15, 1881, from a depth of 36 fathoms, is now 

 in the Norwich Museum (Southwell, Zool., June 1881, 

 p. 258).

 Arthur Strickland.

 a similar shoal went ashore at Cleethorpes, on the Lincoln- 

 shire shore of the Humber mouth (G. Norman, Zool., 

 1862, p. 8087).
