The average breadth of the pectoral folds I found to be 80™™ (3.15 
inch.), and that of the eminences between them about 50™™ (1.97 inch.) 
In spite of a minute search for parasitic animals, none could be de- 
tected.

Besides this larger kind of whale, several denticetes occur in the 
waters around the islands, but, as the natives do not hunt them, they 
are captured only when they are cast ashore, which does not happen 
very often. Thus a sperm whale (Physeter macrocephalus?) was cast on 
shore some years ago, yielding a rich harvest of oil and blubber. Be- 
sides an Orca, which is said to visit the rookeries, but of which I have 
not been able to procure any specimen, or even to see one, there are at 
least two species of the family Ziphiide, both undescribed, as I suppose. 
Iam very much indebted to Mr. Grebnitzky for a skull of each of the 
species, for one of which I should like to propose the name Berardius 
bairdii, as a slight token of my esteem and gratitude. 
As I am now almost without any literary means, I find it impossible 
to decide with certainty in what genus this species will finally have to 
be placed. But I think that the supposition that this specimen (No. 
1520) is a young Berardius may not be very far out of the way. At 
first I suspected that it is a Dioplodon, but the size of the skull, in con- 
nection with the distinctness of the sutures, the evident maxillary crests, 
and the terminal position of the teeth, very soon led me to the above 
conclusion.
