HABITAT. Galapagos Islands (specimens in Mus. Comp. Zool., Hassler 

 Exp.*) and shores and islands of South America, from Chili and the Rio de la 

 Plata southward. , 



* Specimens of both Otaria jiibata and Arctocephalus australis were col- 

 lected by members of the Hassler Expedition at the Galapagos Islands, show- 

 ing that they both range much farther northward than has hitherto been gen- 

 erally supposed. For the following observations respecting their numbers 

 and habits I am indebted to my friend Mr. J. H. Blake, artist of the Expe- 

 dition, who has kindly transcribed them from his note-book: 



"Charles Island, Galapagos Group, June 10, [1872]. On an island at the 

 eastern side of Post-Office Bay is a Sea Lion rookery, where at almost any 

 time can be seen hundreds of Sea Lions lying at a little distance from the 

 water. Two of our company, in a little boat about ten feet long called the 

 ' Dingy', went near the shore where they were, when the Seals immediately 

 ran into the water and surrounded the boat. The Seals came close to and 

 under the boat, so that there was danger of their capsizing it, some of them 

 being as large as the boat, and some were even larger ; hence it was deemed 

 prudent to leave them. Toward evening the Captain, with others, took a 

 larger boat and landed on the shore below the Seals, and while they were 

 running toward the water one measuring six or seven feet in length was shot. 

 Many of them were of enormous sijze, and great numbers could easily have 

 been killed. They made a noise when rushing to the water louder than the 

 waves on the shore. We saved one skeleton, and next day two half-grown 

 Seals were brought on shipboard and also saved. 



"Jarvis Island, June 16, 1872. At this island we saw many Seals, and some 

 were killed, one small one being preserved in alcohol. I went on shore in 

 the second boat, and as our boat landed we were surrounded with Seals of 

 different sizes, which came near the boat. Near where we landed was a 

 mother Seal and her two young ones lying together in a shallow excavation 

 they had made in the sand. They lay very quietly and appeared to be not 

 much disturbed by our presence as we gathered about them, except when 



we offered to touch the young The mother was about six feet long, 



and of a light grayish color, with the head small and shaped like that of a 

 dog. The young resembled their mother but had shorter noses and were 

 about three or four feet long. 



"In walking along' the beach I came to another small rookery where 

 there were family groups similar to that above described, lying about in all 

 kinds of positions, and so comfortably situated I did not disturb them. 

 One Seal, about six or seven feet long, which I met with at some distance 

 from the water, I drove some distance to study its movements in walking 

 and running. It would nearly raise itself from the ground and walk like
