feathers, the chest pale brown, upper tail-coverts pale browu, otherwise like adnlts. 

 This specimen, however, is probably not in the first plunia<;e, but in a transitional 

 one. Its eyes were found to be " brown with light ring, liill greenish blue, gular 

 sac greenish blue, feet Icail-colonr and bntf " (llnll). 



This species was found breeding on Abingdon, Hood, and (Janlner Islands. 

 It lays one or two eggs, generally two, in hollows iu the ground among the rocks. 

 The eggs arc like those of other siiecies of Sula, i.e. very light blue, and covered 

 with a chalky white deposit. They vary much ia size and shajje, measuring 5{) by 

 45, 67 by 43, Go by 44, 00 by 43, and 58 by 45-5 mm.

We liave no evidence of this species occurring in the Galapagos Archipelago at 

 all. It is possil.ile tliat the specimen called I )i/.iporH.s li;Hro<iusti'r (= Snla sida) by 

 iSundevall {P. Z. S. 1871, p. 1:^5), caught in tlic arciiipelago by Kinberg, that one 

 caught on board the vessel near Tower Island by Habel, and which escaped after- 

 wards, and the birds seen by Messrs. Baur k Adams on Bindloe and Cowley 

 Islands, were -S'. birivstcri (or S. tsula brcwxtcri as it might Ije more correctly 

 named, in view of the siniiliarity of the female to S. sula sula), but it is just as 

 possible that they were young of (S. neboiixi. 



One specimen of S. brewsteri was obtained by R. H. Beck on tlie vessel at 

 110° long., 11-20' lat. N., on January 11th, l89S. K female. "Its feet and tarsi 

 yellowish pea-green, bill light horn-colour with a greenish cast, gular sac pea-green,

* We may here mention tlint, if Ihc twelfth edition of Linuaous (17l'>6) is aoceplod as the starting- 

 point of zoological nomenclature. Carba Lacepedc would be the generic title of this genus. (Jrant in Cat. 

 B, llriU Mils. XXVI. accepts PhalacrtH-ixra,p Brisson 17G0, while he rejects Oiwcrotalns Brisson 1700. 

 Such inconsistent nomenclature can surely not be recommended.
