Postcript, 21st December, 1874. — A short notice of this whale was sent 

 to Dr. Gray and published in the Annals and Magazine of Natural History, 

 and from the character of the blade-bone Dr. Gray was inclined to make it 

 into a new genus under the name of Stenobalcena xanthogaster. The drawing 

 of the blade-bone sent to Dr. Gray and given in the paper referred to, was, 

 however, only from a rough sketch by Mr. A. McKay, and is not like the 

 macerated bone, several large cartilaginous prolongations included in his 

 outline having disappeared. The connect form of the macerated bone is 

 shown in pi. XVIII. , fig. 6. 



In September last Captain Fairchild of the Government steamer Luna 

 successfully removed the whole of the skeleton from Port Underwood to Cow 

 Bay, in "Wellington Harbour, a sandy beach remote from the town ; and 

 since then all the bones except the skull, which had worked down the bank into 

 ten feet water at low tide, have been cleaned and transferred to the Botanic 

 Gardens. The skull, though cut into four parts, is so large that it must 

 remain where it is until some means of removing it is available. 



The following is a description of those parts of the skeleton which are 

 available for examination : 



Skeleton. — Cervical vertebrae, free ; second cervical with expanded alseform 

 processes, with a small foramen at the base ; third, fourth, fifth, and sixth 

 with slender lateral arches ; seventh, with incomplete lateral arches. 



Atlas with the articular surfaces extending for four-fifths of the circum- 

 ference of the central foramen, which is twice as high as wide and slightly 

 constricted at two thirds of its height by the projection of the superior interior 

 angles of the articular surfaces ; the lower part receives the oblong odontoid 

 process, the upper or neural arch being wider than high, and surmounted by a 



blunt triangular spine throwing forward a process that encloses a short anterior 

 canal on each side of the base of the arch ; the anti-basilar ligamentous groove 



separating the articular areas inferiorly is narrow linear, and only excavated 

 to the depth of the cartilaginous layer ; the superior lateral processes are 

 short, solid, blunt, pointed, and feebly angulate in front ; no inferior lateral 

 process. 



Axis with a rough odontoid area, but not an elevated process, surrounded 

 by a horse-shoe shaped articular surface ; centrum of this and all the
