356 On the Humming-birds of the West Indies. 



This species, if it is really entitled to such a distinction, is 

 found exactly between O. ci'istatus of Barbadoes and St. Vin- 

 cent, and 0. exilis of the Virgin Islands and Nevis. It has 

 perhaps a little more blue upon the crest ; but if the locality is 

 wanting, it is not an easy matter to separate specimens from O. 

 exilis, to which the present bird bears a very close resemblance.

Hab. Cuba. 



The island of Cuba possesses at least two species of Humming- 

 birds not met with elsewhere, the Calypte helence and the one now 

 under consideration. It is rather common in its native place, 

 and has never been known to leave the island.

Hah. St. Domingo. 



Very strange is the fact that so many of the West-Indian 

 islands appear to possess certain species of this family that are 

 not met with elsewhere. St. Domingo is another proof of this 

 as it is the only spot where the present species has been dis- 

 covered ; and we may be safe in believing that it never leaves 

 that island; for so conspicuous a bird would not likely be over- 

 looked by any ornithologist visiting the neighbom'ing groups in 

 pursuit of their feathered inhabitants.
