XLVI. — Notes on a Specimen of Sowerhy^s Tl'7<a/e(Mesoplodon 

 bidens*) , stranded on the Norfolk Coast. By T. SOUTHWELL, 

 F.Z.S., and Sidney F. Harmer, M.A., F.Z.S. 



[Plate XV.] 



On the 19th December, 1892, we received intimation tliat a 

 " large fish " accompanied by a young one had come ashore 

 on the previous day at Overstrand, near Cromer, and ou the 

 following day we visited Overstrand together with the expec- 

 tation of seeing one of the commoner species of Cetacea, but 

 were agreeably surprised to find that the animal which had 

 been stranded was a fine adult female specimen, 16 feet 

 2 inches in length, of Sowerby's Whale. It had been disco- 

 vered on the morning of the 18th December left in shallow 

 water by the receding tide, still alive but feeble, and, after 

 being anchored to the shore for security, had been placed on 

 a trolly and carried to the top of the cliff; it died, however, 

 before it was taken from the water. Previously to our arrival 

 on the scene it had been eviscerated, and was lying in a shed 

 on the top of the cliff", a foetus, 5 feet 2 inches long, having 

 been extracted from it. 



* Professor Sir W. Turner, in a recent paper on its occurrence in the 

 Firth of Forth, has adopted the generic name Micropteron for this animal, 

 a.s proposed by A. Wagner in 1846, and used by Eschricht aud G. Cuvier; 

 but for the reasons assigned by I'rofessor Sir W. Flower, in a footnote to 

 his paper on the "Recent Ziphioid Whales'" (Tr. Z. S. viii. p. 208), we 

 prefer to retain the more familiar term Mcsoplndon, as applied by M. P. 

 Gervais in 1850.
