AVES DIOMEDEID/G. I71 



"That by a judicious twisting or screw-like action of the wings at the 

 shoulder, in which the pinions are alternately advanced towards and with- 

 drawn from the head in a manner analogous to what occurs at the pelvis 

 in skating without lifting the feet, birds of this order can not only main- 

 tain the motion, which they secure by a few energetic flappings, but, if 

 necessary, actually increase it, and that without either bending the wing, 

 or beating the air." 



"Whether, however, this is a correct or sufficient explanation of what 

 appears at first sight a very perplexing phenomenon, I do not venture to 

 offer any opinion." (Cunn. Nat. Hist. Str. Magell. 1871, pp. 225-226.) 



From the Strait to the Falkland Islands he writes: "We observed 

 some very fine albatrosses, and a solitary penguin, which was progressing 

 at a rapid rate by means of a series of flying leaps, presenting much the 

 appearance of an animated beer-bottle." (Cunn. Nat. Hist. Str. Magell. 

 1871, p. 291.) 



Mr. R. Vallentin in his notes on the Falkland Islands says: "Only a 

 visitor to this archipelago. Their nearest nesting place is South Georgia ; 

 a desolate uninhabited island about 800 miles south-east of the Falkland 

 Archipelago. I have in my collection three eggs of this species, which 

 were given to me by the captain of a South Sea whaler, who put into 

 Stanley on his return from those inhospitable regions. He found the 

 nests of these birds fairly numerous along the high ground round Cum- 

 berland Bay, South Georgia."
