The skull, the cervical vertebra?, scapula, and imperfect pectoral limb of this animal 

 are preserved in the Museum at Wellington, and have been figured on a reduced scale 

 in the Transactions of the New-Zealand Institute, vol. iii. Although there was but a 

 single tooth on each side of the lower jaw, near the apex, the skull in form and size so 

 closely resembles that in the Paris Museum, that it is difficult to believe that they are 

 not specifically identical. 



Though no complete description of the portions of this animal which were preserved 

 has yet been published, the following paragraph relating to it by Dr. James Hector, 

 F.R.S., is important: — "The preparation of the nose (figures 4 a & 4 b) shows that, 

 notwithstanding this is a full-sized animal, the tooth is still sheathed in the gum, 

 being imbedded in a tough cartilaginous sac, which adheres loosely in the socket of 

 the jaw, and is moved by a series of muscular bundles that elevate and depress it" 1 . 



The dimensions of the skull are thus given by the same naturalist : — 



inches. 



Length of head 59-5 3 



Length of nose 3T0 



Length of dental groove 15 - 



Length of lower jaw 43*0 



Width of notch 14-5 



Width at orbits 24-5 



Width at blow-holes 7-0 



Width at nose 5'0 



Height of occiput 19-5 3

2 This is evidently a mistake, as it is far too large for the other dimensions. According to the figure it should 

 be 47-5. 



3 The smaller specimen, 9 feet 3 inches in length, which was described in the 2nd vol. of the Trans. N.-Z. 

 Inst. (p. 27) under the name of Berardius arnuxii, and which has since been named by Dr. Gray Berardius 

 hectori (Ann. & Mag. Nat. Hist. August 1871), belongs, as above mentioned, to a different section of the 

 group.
