 Guatemala {Salvin). 



An occasional winter visitant in Cuba, having been observed by 

 Dr. Gundlach in some numbers in 1839 and 1850. Mr. March 

 says that it is sometimes found in Jamaica in company with the 

 Pintail. Col. Grayson found it at Mazatlan. 



Salvin once killed a single specimen of the Canvas-back on the 

 Lake of Duenas ; but this is the only instance of its occurrence so far 

 south that we are acquainted with. 



Genus 3. Clangula. rp 



Clanffufa, Fleming, Phil, of Zool. ii. p. 260 (1822) C. glaucion*. 



Glaucion, Kaup, Nat. Syst. p. 53 (1829) C. glaucion. 



Bucephala, Baird, B. of N. A. p. 796 (1860) .... C. albeola. 



Clangula is another high northern genus, of which two species 

 have been casually met with just within the confines of the Neotro- 

 pical Region. 



1. Clangula glaucion. 



Anas clangula et A. glaucion, Linn. S. N. i. p. 201.* 



Clangula americana. Cab. J. fiir Orn. 1857j p. 230 (Cuba). 



Bucephala americana, Baird, B. of N. Am. p. 796; Lawr. Mem. 

 Bost. Soc. N. II. ii. p. 315 (Mexico). 



Hab. Cuba {Lembeye) ; Mexico (Grayson). 



Dr. Gundlach tells us that Lembeye believed he had seen an ex- 

 ample of the Golden-eye on a pool in Cuba, but was not able to 

 get it. We observe that Dr. Gundlach omits this species altogether 

 in his ' Revista,' and still more recently published notes in the 

 ' Journal fiir Oruithologie ' (1875). It may, however, find a place 

 in this paper on the authority of Col. Grayson, who shot it at 

 Mazatlan. 



2. Clangula albeola. 



Anas albeola, Linn. S. N. i. p. 199 (1766). 



Clangula albeola, Bp. Comp. List, p. 58; Cab. J. fiir Orn. 1857, 

 p. 230 (Cuba). 



Bucephala albeola, Baird, B. of N. Am. p. 797 ; Gundl. Repert. 

 F.-N. i. p. 390, et J. fiir Orn. 1875, p. 383 (Cuba). 



Hab. Cuba {Gundlach). 



A specimen of this Duck has been once observed in the market of 

 Havana, and was procured by Gundlach. 



* Fleming, it is true, puts Anas glacialis first in his list; but A. clangula i? 

 obviously his type, and therefore we do not use Baird's term Bucephala.
