entrance to Saldanha Bay (Cape Colony), where Mr. W. L, 

 Sclater met with countless numbers, sitting so close as to be in 

 many cases almost touching one another (" Ibis," 1904, p. 84). 

 S. cape.nsis is a valuable depositor of guano, which is the reason 

 why in company with the Penguins it meets with protection. 

 Some extraordinary particulars have been collected by Mr. 

 Sclater (see " Ibis," 1904, p. 87), from which it appears that in 

 one year alone — 1902 — the Gannets on Bird Island furnished

 were collected, besides a great deal more from the Gannet- 

 stations on Ichabo and Possession Island.

 because the name of Sula australis — which was originalh^ sug- 

 gested in Sir Joseph Banks's Icon. ined. 30, by Forster (?) — 

 had been already made use of by Mr. J. F. Stephens in his 

 continuation of Shaw's " General Zoology " in 1825 (VIII., 

 Part I., p. 104) for Sula sula {S. leucogastra, B.). 



In " The Birds of New Zealand " (Supplement, p. 46) Sir 

 W. Buller has given an account of a breeding station of Sula 

 serrator at Cape Kidnappers. Some particulars of its nesting
