A common migratory species from tlie north, being found 

 in winter in Easterm Mexico and Eastern Central America. 

 It is hardly known to occur on the mountain-slopes towards 

 the Pacific, and but some few wander as far as Panama. 



In these islands it appears to be very abundant, as well as 

 on the adjoining mainland and in Cuba.

Mr. Gaumer has sent us a large series of this interesting 

 bird, which appears to be very common on the island of Cozu- 

 mel, and is probably found on most of the islands of this part 

 of the coast, as well as on the mainland. Mr. Ridgway, in 

 his table of distribution of Cozumel birds, states that 

 M. glabrirostris had not then been recorded from Yucatan, 

 but he has overlooked the statement in M. Boucard's list of 

 its occurrence there.

Cozumel I. 



Mr. Gaumer has sent us a good series of specimens of this 

 species, all bearing the characters whereby it may be dis- 

 tinguished from H. longirostris. There is some variation in 

 the density of the spots on the under surface, but otherwise 

 there is great uniformity in their plumage between specimens 

 of the series.
