which I have not seen. Except in the upward curve of the beak, and the 
less development of the vomerine callosity, this skull resembles Petrorhynchus 
capensis, Gray, l.c. 345*. 
Since the above was written I have examined the skull of a very old female 
specimen of this whale, captured in Port Cooper, the complete skeleton of which 
is being prepared in the Canterbury Museum ; it has the same measurements 
and general form with the Chatham Islands specimen, but the sperm cavity 
in front of the blow-hole is covered in by a thin callous plate. The teeth at 
the extremity of the lower jaw were nearly absorbed, being reduced to 
conical fangs, with rough surfaces, having constricted sub-cylindrical summits 
terminating in short acicular tips, and were so deeply imbedded in the gums 
that their presence was overlooked until after maceration. 
Dr. Haast informs’ me that the length of this whale was 28 feet, and 
that it had no dorsal lobe. The colour was black above and white beneath, 
but the back and sides were marked with oval spots 2 to 3 inches across, 
like the skin of a leopard. 
The rostrum of an individual of this species, found at Lyall Bay, near 
Wellington, having a less upward curve, is in the Colonial Museum,

Teeth 2, on sides of lower jaw, strap-shaped, produced, arched, obliquely 
truncate at the end, with a conical process on the front of the terminal edge. 
Lower jaw, Chatham Islands, obtained by Mr. H. Travers, 
The total length of this jaw is 2 feet 9 inches ; the posterior third is thin, 
convex externally, expanded, having a height of 6 inches. It is then straight, 
and compressed in its middle third as far as the commencement of the 
symphysis, which unites the rami for their anterior third into a straight
