Of the diseases of the Antarctic seals there is but little to be said. They are not 
exempt. from the ravages of unfriendly bacteria, for one may see their wounds freely 
suppurating, and in more than one case the eyes both of adult and young have been 
seen streaming with pus. They are also apparently subject to uric acid troubles, for 
the kidney tubules have been found in one or two cases occupied completely by renal 
calculi. In the coronary arteries also, very definite atheromatous deposits may 
occasionally be found.

For the history of the type specimens, and of the earliest descriptions of this seal, I 
must refer my readers to the account given by Captain Barrett Hamilton under 
Ogmorhinus in the Report on the ‘Southern Cross’ Collections (pp. 25-27). The 
synonomy there given also covers the matter so completely that I could but quote 
the paragraph word for word. I venture in this paper, however, to return to 
Stenorhinchus, a name which is certainly open to objection, but not perhaps to so much 
as are Ogmorhinus and Stenorhynchus, while it is certainly preferable to Hydrurga. 
Stenorhinchus, then, has a very extensive range, not only far to the south and 
within the Antarctic Circle, but also throughout the Southern temperate regions. It 
has been recorded, for example, from the Falklands, Campbell Island, Desolation 
Island, New Georgia, Lord Howe Island, Tasmania, Cape Horn, New South Wales, 
Patagonia, Kerguelen, and various parts of the coast of New Zealand (Port 
Nicholson and Wellington Harbour, the Waikato and Wanganui rivers), where Sir 
James Hector says it is a commun but a solitary animal. “It frequently comes on 
shore, and, notwithstanding its feeble powers of locomotion, scrambles far back into 
the bush in flat country, and occasionally ascends rivers for a long distance.” Farther 
south, Captain Larsen reported it from Louis Philippe Land in November, Mr. Bruce 
from Graham’s Land, and Mr. Borchgrevink from Robertson Bay in September. Sir
