38 MEMOIRS OF THE NUTTALl, ORNITHOLOGICAL CLUB 



42. Nyroca valisineria (Wilson). 

 Canvas-back. 



Gundlach reports that in 1842 and 1850, a few Canvas-backs appeared 

 in Lake Ariguanabo. I never have seen one in Cuba. 



43. Nyroca affinis (Eyton). 

 Little Bluebill; Cabezon. 



A winter visitor to the larger, open lakes. On almost every visit 

 to Lake Ariguanabo I have seen large flocks cutting about at sundown 



44. Nyroca collaris (Donovan). 

 Ring-necked Duck. 



The Ring-necked Duck appears almost every year in numbers about 

 equal to those of the Little Bluebill, according to Gundlach. As a matter 

 of fact, I believe that the species are often confused by the local gun- 

 ners and that this one is very decidedly the rarer of the two. It certainly 

 appears nowadays much less often in the Havana market, which I often 

 have visited daily to examine the 'game' exposed for sale. 



45. Charitonetta albeola (Linne). 



BUFFLEHEAD. 



A rare accidental visitor. Gundlach once got one in the Havana 

 market.
