prevails on the rest of the under parts ; the red streaks in this 

 specimen are faint. In this phimage it agrees with alhicollis, 

 Gmelin, which has been generally placed as a synonym to 

 (Bstiva, but it must now be restored as an independent species. 



Gmelin states that the female has the hind neck greenish-ash 

 — if this is the correct plumage of the female, the young male 

 appears to resemble it. 



Gmelin gives St. Domingo as the habitat of his species, 

 which adds to the probability of the Cuban bird being similar. 



The restoration of this species is another instance of the im- 

 portance of a strict comparison of birds from different locali- 

 ties which are thought to be identical. 



Mr. Cassin was much interested in the above specimens, 

 never having seen any from Cuba, more particularly as he was 

 at the time engaged with an investigation of the species allied to 

 (Bstiva. He suggested that I should examine them carefully, as 

 he thought the Cuban species, from its recorded habits, would 

 prove to be different from cBstiva, and was probably one of the 

 older species confounded with it. 



From Dr. Gundlach's note it is evident he also suspected it 

 was different from the United States cestiva, for the same rea-^ 

 son.

Dr. Gundlach sent me his specimen of the so-called picsilluSf 

 "which on examination proves to be acadicus. 



It was hardly probable that pusillus^ which inhabits west of 

 the Mississippi, would occur in Cuba.
