 (Grayson) ; Guatemela, Lake of Duerias (Salvin). 



Although certainly resident in Cuba, this is a rare species. Dr. 

 Gundlach has found it only in the neighbourhood of Havana. 

 Salvin met with it breeding on tbe Lake of Duehas in Guatemala, 

 where it is the only Duck resident throughout the year. He ob- 

 served that it diminished in numbers during tbe period of the spring 

 migration. It builds in May amongst the reeds on the margin of 

 the lake, making a nest of dead flag with a little down. The eggs 

 are rough in texture, and much resemble those of the European 

 E. mersa.

This Erismatura was first obtained in Chili by Mr. C. Crawley, 

 and described by Eyton from his specimens in the British Museum. 

 Philippi and Landbeck state it is common on all the lakes of the 

 Central Provinces. They at one time described the female as of a dif- 

 ferent species (E. vittata), but subsequently acknowledged their error 

 (see P. Z. S. 1868, p. 531). From Chili this species spreads north-
