of a Voyage round the World. 51 



3. Larus modestus Tschudi. 



Larus modestus Saunders, Cat. B. xxv. p. 223. 



(J imm., Feb. 17th. Iris hazel; bill black; tarsi and 

 toes blaek, with olive-brown wash. 



I saw several of these graceful little Gulls in Valparaiso 

 Bay, but, like all the birds there, they were very wild. 



4. Stercorarius crepidatus (Gin.). 

 Stercorarius crepidatus Saunders, Cat. B. xxv. p. 327. 



cJ . Iris black ; bill black ; tarsi bluish grey ; feet black. 



I saw numbers of small Skuas in the bay at Valparaiso of 

 both the light and dark phases. I thought at the time that 

 they might be S. pomatorhinus. I secured one example only, 

 as they were extremely wary. My specimen is almost wholly 

 white below, with a quantity of white on the head ; but, on 

 comparing it with the large series in the British Museum, 

 I find that it must be S. crepidatus, although it is far 

 whiter thau any other specimen in the series. This locality 

 is much further south on the Pacific coast of America than 

 any at which this species has been obtained before. 



5. Puffinus creatopus (Coues). 



Puffinus creatopus Salv. Cat. B. xxv. p. 370. 



2 . Iris hazel ; bill yellowish flesh-coloured, tip black ; 

 tarsi and toes flesh-coloured, outer toe darker. 



This Shearwater was not uncommon in Valparaiso Bay, 

 but was very shy and very hard to shoot. It used to come 

 closer in towards evening. I rarely saw it sitting on the 

 water. 



6. Puffinus griseus (Gm.). 



Puffinus yriseus Salvin, Cat. B. xxv. p. 386. 



£ $ . Iris black ; tarsi and toes slate-coloured in front, 

 black behind ; webs black. 



This Shearwater was very abundant off Valparaiso when 

 we were there, though difficult to approach. Flocks of 

 several hundreds used to come into the bay every evening 

 and sit on the water. Before dusk I used to see them 

 sweeping along the coast in a continuous stream over the 

 sea outside the bay.
