380 MESSRS. SCLATER AND SALVIN ON ["Apr. 4, 



Linhean type) occur within the Neotropical Region. Three of them 

 are stray visitors from the north into the Antilles ; the remaining 

 two are peculiar Antarctic species. 



1. Anas boschas.

Hub. Cuba (Gundlach) ; Jamaica (March) ; Mexico (Be Oca, 

 Grayson); Panama (M'Leannan). 



According to Dr. Gundlach, A. boschas is rarely seen wild in 

 Cuba; but in 1850 a flock on passage from the north settled in the 

 lagoons near Cardenas, and the bird is occasionally to be seen in 

 the market of Havana. Mr. March says it is rare in Jamaica. In 

 Central America it has been recorded from Mexico and Panama, but 

 nowhere else. 



2. Anas obscura. 



Anas obscura, Gin. S. N. i. p. 541 (1788) ; Baird, B. of N. Am. 

 p. 775 ; Cab. J. f. Orn. 1857, p. 229 (Cuba); March, Pr. Ac. Phil. 

 1864, p. 72 (Jamaica) ; Scl. & Salv. Nomencl. p. 129 ; Lawr. Mem. 

 Bost. Soc. N. II. ii. p. 314 (Mexico). 



Hab. Jamaica (March) ; Tepic, Mexico (Grayson). 



The Dusky Duck is said to be of rare occurrence in Jamaica. In 

 Cuba, Dr. Gundlach formerly suspected its occasional presence, but 

 does not mension it in his last 'Revista de las Aves Cubanas.' In 

 Mexico it has hitherto only been noticed at Tepic by Grayson. 



3. Anas specularis.
