The Hooded Merganser is of rare occurrence on passage in Cuba 

 and does not appear to have been noted elsewhere within our limits' 

 except in South-eastern Mexico. '

Ihis scarce Merganser was first described by Vieillot from Dela- 



lande s specimens in the Paris Museum, and subsequently figured by 



the same author under another name. Lichtenstein gives slo Paulo 



as Its locality ; and Natterer obtained five examples on the River 



Ytarare in the southern part of that province in August 1820 One 



of these skins marked as the female sex, is now in the collection of 



fealvin and Godman, whence our description is taken. 



IV. Table of the Geographical Distribution of the Neotropical 

 Anatidx, with remarks thereon. 



On referring to the last column of the Table (pp 410 & 411) it- 

 will be seen that out of the 62 species of Anatidae included in the 

 Neotropical list 25 are likewise found in North America. Of the«e 

 25, however, two {Bendrocygna fuha and Qvercpiedula cyanoptera) 

 are visitors from the south ; and the Nearctic species which intrude 

 into the Neotropical region (mostly in winter) are, so far as is at 

 present known, 23 in number, namely 



Anser hyperboreus. Anas boschas, 



ccerulescetis, obscura, 



gambeli, strepera, 



Bermcla canadensis. Querquedula carolinensis
