480 Mr. F. E. Blaauw : Field-notes on some 



was in Tierra del Fuego in the second half of April. I was 

 riding from Porvenir to Jente Grande, on the north-western 

 part of the island, and on my way passed near a large lagoon. 



In this lagoon there were great numbers of Coscoroba 

 Swans; they challenged me with their call of ^' Coscoroba^' 

 as I got near. A little later on, in what I considered to be 

 part of the same lagoon, I saw a few more. 



Unfortunately, I forgot to inquire if the Coscoroba ever 

 breeds in Tierra del Fuego. 



In ' Notes from the Leyden Museum,' vol. xxxv. note i. 

 p. 50, pis. i. & ii., I have described and figured the newly- 

 hatched chick of the Coscoroba, from a chick bred in 

 Woburu Park. The chick is white, with dark grey markings 

 on the head and upper parts. The head-markings re- 

 semble in style those of a Dendrocycna ; those of the back 

 closely resemble those of a chick of a Shell-Duck, but are 

 not so heavy. The Coscoroba, to my mind, is a gigantic 

 Tree-Duck. 



Chloephaga hyhrida. 



I met, for the first time, with the Antarctic Goose in 

 Smith Channel, shortly after having left the Straits of 

 Magellan, going north. They were standing on the water's 

 edge at the base of mighty rocks. The beautiful white male 

 was like a spot of snow, and was visible at a great distance. 

 The blackish-brown female was much more difficult to see. 



During the whole of my voyage through Smith Channel 

 and its continuation, Antarctic Geese were constantly seen. 

 They were generally noticed in pairs or in small families of 

 five to seven, and occasionally I saw a solitary male. They 

 were always near the water's edge and often on bare rocks 

 projecting out of the water. They are entirely confined to 

 the sea-shore, and I never saw them on a sandy beach. They 

 haunt the rocks and the stones on which a peculiar edible 

 s^jecies of seaweed grows, called " Lutche " by the natives, 

 and on which they may be seen feeding when the tide is 

 low. They probably also feed on marine animals, which 

 they find in the same places.
