ZOOLOGY. 



REPOKT on the Bones of Cetacea collected during the Voyage of H.M.S. 

 Challenger in the years 1873-1876. By William Turner, M.B. (Lond.), 

 F.Pt.SS. L. and E., Professor of Anatomy in the University of 

 Edinburgh. 



Peofessor Sie C'. Wyville Thomson having entrusted to me for purposes of description 

 the bones of the Cetacea collected during the voyage of H.M.S. Challenger, I have to 

 report as follows : — 



The specimens which were placed in my hands for examination were — 



A. The skuU, without the lower jaw, of an adult Mesoj^lodon layardi. This speci- 

 men is now in the Oxford Museum, and I am indebted to Professor Eolleston for the 

 opportunity of examining it. 



B. The end of the rostrum, with the corresponding part of the lower jaw, and the two 

 mandibular teeth of Mesoplodon layardi, also in the Oxford Museum. 



C. The skull and a large part of the skeleton of an immature Cetacean, evidently a 

 young Mesoplodon layardi. 



D. A skull with lower jaw from the Colonial Museum, Wellington, New Zealand, 

 marked Ejnodon chathamiensis, but which I regard as a specimen of Zipkius cavi- 

 rostris. 



E. Atlas, axis, and 3d and 4th cervical vertebrge of Humpback whale of New Zealand, 

 from the Colonial Museum, Wellington. 



F. Cervical vertebrae of Right whale of New Zealand, from the Colonial Museum, Wel- 

 lington. 



G. Numerous ear-bones and some fragments of other bones brought up by the dredge 

 from the floor of the ocean.
