2. PoDiCEPS ROLLANDii. Quoi/ €t Gaim. 



Podiceps Eolland, Qiioj/ et Gaim. Toy. cle I'Uranie, pi. 36. p. 133. 



I obtained specimens from the Falkland Islands (March), where it was common 

 at the head of the tortuous bays which intersect those islands ; from a fresh water 

 lake near the Strait of Magellan (February); and from the eastern coast of Chiloe. 

 The male and female have the same plumage. Iris of a fine red colour. Mr. 

 Gould adds that, " this species appears to be as nearly related to the Podiceps 

 cornutus, as the preceding species is to P. nuritns, but is readily distinguishable 

 from it, by the white spot in the centre of the tuft of feathers that spring from the 

 sides of the face." 



3. Podiceps Chilensis. Ganwt. 



Le macas comu, ^c^arrt, No. 443. 



This specimen was procured in a fresh-water lake near Buenos Ayres. 

 Capt. P. King brought home specimens from the salt-water channels in Tierra 

 del Fuego, where it is excessively numerous. It often makes a very melancholy 

 cry, which suits the gloomy climate of those desolate shores. 



SpHENiscus HuMBOLDTii. Meycn. 



Spheniscus Humboldtii, Mei/cn. Nov. Act. Acad. Caes. Leop. Car. Nat. Cur. 1834, 110. pi. 21. 



My specimen was obtained near Valparaiso. Meyen, who first described 

 this bird, procured it from the coast of Peru. 



Puffin us cinereus. Steph. 



Puffinus cinereus, Steph. Gen. Zool. xiii. p. 227. 

 Procellaria puffinus, Linn. 



This bird frequents the seas on the whole coast of South America. I 

 obtained specimens from Tierra del Fuego, Chiloe, the mouth of the Plata, and Cal- 

 lao Bay on the coast of Peru. It is likewise known to be common in the Northern 

 Hemisphere ; this species, therefore, has a most extensive range. It generally 

 frequents the retired inland sounds in very large flocks ; although, occasional!}', 

 two or three may be seen out at sea. I do not think I ever saw so many birds of 

 any other sort together, as I once saw of these petrels, behind the Island of 

 Chiloe. Hundreds of thousands flew in an irregular line, for several hours in one 

 direction. When part of the flock settled on the water, the surface was blackened ; 

 and a cackling noise proceeded from them, as of human beings talking in the 

 distance. At this time, the water was in parts coloured by clouds of small 

 Crustacea. The inhabitants of Chiloe told me that this petrel was very irregular
