Major; supra fuliginoso-olivaceus, dorso postico magis virescente, pileo haud cinereo tincto, superciliis sordide 
albis; subtus similis, sed pallidior medialiter albescens, crisso et subalaribus vix flavo tinctis ; remigibus 
intus albis. Long. ale 3:05, caude 2°25, rostri a rictu ‘85. (Descr. maris ex Belize. Mus. Smiths. 
exempl. typ.) 
Hab. British Honpuras, Belize (C. Wood !, Berendt). 
Of this species we describe the type specimen kindly lent us for that purpose by 
the authorities of the Smithsonian Institution, the only other example we have seen 
being one in the Museum of the Boston Society of Natural History. They evidently 
belong to a distinct species, which we have not met with ourselves. In the original 
description Mr. Lawrence compares it to V. olivaceus and the southern form of it 
V. agilis; but in the ‘ History of North-American Birds’? it is compared to V. phila- 
delphicus, on account of the absence in both species of a dusky line on the sides of the 
crown. From V. philadelphicus it differs in its larger size and in not having any ashy 
tinge on the crown. 
It exceeds even V. olivaceus in size, from which it differs also in not having an ashy 
crown. In some respects it resembles V. calidris, from which, however, it may be 
known by the absence of the rictal streak and the browner tint of the under- 
surface. 
The presence of a distinct local species of this genus in British Honduras is some- 
what remarkable; and we look forward with interest to the receipt of additional 
specimens.
