Adult. Similar to C coMearia, but distinguished by the colour 

 •of the throat and breast, which are pale vinous or light tawny. 

 Total length 18 inches, culmen 3'3, wing 11-3, tail 4*2, tarsus 3'3. 



Of the distinctness of the Central American Boatbill, there can, 

 I think, be no question. In shade of grey there is much variation 

 in a series, and I inclined at first to the opinion that the birds from 

 certain localities were darker than those from other countries ; but 

 I find that light and dark-coloured specimens have been procured in 

 the same districts, and it is possible, therefore, that the darkness of 

 the grey tint may be a sign of immaturity or non-breeding plumage. 



Younf/. Never so rufous as the young of O. cochlearia, but other- 

 wise similar, and having the fianks streaked with white. 



Hah. Central America from Mexico to Panama.
