Hair-Seals were noted on the group bj Stokes ; and Gilbert secured 

 specimens which were figured by Gould in his ' Mammals of Australia,' as 

 well as writing an account of their habits. They were evidently very plentiful 

 on the Abrolhos at that time — at any rate, in the breeding-season. Nowadays 

 only a few individuals are to be seen there, as on most other parts of the 

 West Australian coast. 



I have given a full synonymy of this species, as, though Gould expressly 

 states that he was not sure of the proper name to use for his Abrolhos speci- 

 mens, he was, nevertheless, followed by Ogilby and by Lucas and Le Souef, 

 the only recent writers, so far as I am aware, who have mentioned the 

 species. I had reached the conclusion that Peron's name should be used 

 before I read the paper by J. W. Clark, and was confirmed in my view by 

 finding that he had reached the same conclusion in 1875. 



Cetacea. Bal^nid^e. 

 Megapteba longimana, Rud. Humpback Whale. Portions of the 

 skeleton of a whale of this species were lying about on the shore of Pelsart 

 Island. In Oct. 1914, when travelling down the coast on the ss. 'Minderoo,' 

 I saw a number of Humpbacks in the neighbourhood of the Abrolhos. 

 Prof. Dakin tells me that some came into Whale Bay in the Pelsart Group 

 during his visit in 1915 — apparent!)', as we were told by the fishermen, to 

 scrape themselves on the rocks. 



Delphinice. 

 [Sotalia gadamu (Owen). Gadamu Dolphin. This appears to be the 

 common "Porpoise" of the West Australian coast, and I presume that the 

 specimens seen at the Abrolhos belong to this species, but there is at present 

 no definite specimen from the group to determine the point.]
