The only anatomical notes that I know of in existence, with regard to this curious bird, are 

 those of Mr. Yarrell, in the Zoological Proceedings (1830, p. 25), which in giving our specific 

 account of it, we cannot do better than extract. 



Affinities. Another rather anomalous genus, more closely connected, bowever, with the 

 geese than the preceding.
