are also furnished by Mr. D. le Souef in " The Victorian Natur- 

 alist " (1901-2, p. 181), and by Mr. A. H. Mattingley in the same 

 journal (1908, p. 12). Mr. Mattingley, who spent several nights 

 sitting up in an Australian Gannetry, states that the nestling 

 S. serrator, when quite young (apparently about five days old 

 from the photograph) and devoid of feathers, crawls about on 

 all fours, using legs, wings, and beak as aids to progression. 

 Subsequently adding some further particulars in a letter, he 

 says : " Sula serrator only lays one egg, but one often finds 

 addled eggs that have been thrown out of the nest. Some I 

 have found intact buried under the guano forming a nest ; 

 these nests were evidently a second attempt at brooding after 

 a first failure ..." Its habit of covering its egg with its 

 foot has been already referred to (p. 352). Mr. Mattingley 

 has obliged me with a series of excellent photographs, two 

 of which, taken on Cat Island, Bass Strait, are here repro- 

 duced ; and I am also indebted to Mr. A. J. Campbell of 

 Melbourne for a photograph from the same locality, which shows 

 that Australian Gannets when sitting on their nests face 

 different ways, a point about which there has been some dis- 

 cussion {see p. 101). In Mr. Campbell's "Nests and Eggs of 

 Australian Birds," 1901 (II., p. 981), there is a good account 

 of *S^. serrator, which evidently closely resembles *S^. bassana in 

 its habits.
