Note on Seals, Plate IV.; the position and outline of the adult female is taken from a photograph 
supplied to me by Mr. McGregor Wright, of Wellington, N.Z., who happened to visit the 
Auckland Islands during our stay there, and kindly gave me permission to use his photo- 
graphs in this publication. See also figs. 33 and 34, p. 64. 
On her homeward journey from the Antarctic to New Zealand, the ‘ Discovery’ was 
anchored for a fortnight (March 15th to 29th, 1904) in Laurie Harbour, at the north- 
eastern end of the Auckland main island. This stay brought us in touch with Hooker's 
Sea-lion (Arctocephalus hookeri), which we found to be abundant in our neighbourhood, 
a large number frequenting a stretch of sandy shore about half a mile long on the 
southern side of Enderby Island, which lies just outside and to the north of Laurie 
Harbour. In Laurie Harbour itself we were visited by adult females and young adult 
males, but the oldest and largest males were only to be seen on the sandy beach of 
Enderby Island, and an account of our visit to it will convey the greater part of our 
observations concerning the habits of the animal. 
It may first, however, be stated that the exact range of Hooker's Sea-lion has not 
been very satisfactorily determined. There is much doubt as to the propriety of con- 
sidering the variously named species of Arctocephalus as distinct, and until this matter is 
cleared up it is almost impossible to say where Arctocephalus hookeri has or has not been 
found. Gray reports it from the Falkland Islands and Cape Horn, and probably the 
south coast of Australia. Itis also said to frequent the west coast of New Zealand, Bass 
Strait, and the west coast of Tasmania (Sir James Hector). It quite certainly occurs 
abundantly on the shores of the Auckland Islands; and the sandy beach of Enderby 
Island seems to provide the requirements of a breeding “‘ rookery,” since we there found 
old males with their harems around them, as well as two young ones quite recently 
born. Along the whole length of this sandy beach were these Sea-lions, the majority 
young males and females; but there were also about twenty full grown and very large 
dark brown bulls“ with thick manes of short, rough and curly hair (figs. 31 and 
32, p. 60). 
Wherever we went into the bush which covered the island, even half a mile in- 
shore, in the thickest scrub or amongst the mounds of tussac grass, often half-way 
up a quite considerable hill, we found ourselves confronted by half awakened Sea-lions. 
In the scrub adjoining this sandy beach we discovered a very young one, dead, but 
quite fresh. This was a particularly interesting specimen,* because it had just 
commenced shedding the reddish-brown hair in which it was born. From nose to tail 
its skin measures 42 inches. The hind flippers extended behind add another 8 inches 
to its length, and the fore flippers are 9 inches long. The bright chestnut-red hair 
which covers it is fine in texture, straight and abundant, each hair measuring 3 inch 
(17 to 18 mm.) in length. The ventral surface is as red and as dark as the dorsal, but 
the shoulders and the lower part of the back and flanks are of a decidedly darker shade 
* There is, in the B. M, Coll., a similar skin of Arctocephalus hookeri of about the same age, showing 
exceedingly well the pale crown, mentioned on p. 61; but the skin has no history.
