metallic rose purple (the upperparts in true G. martinica are almost liver 

 brown and the metallic gloss is lilac) ; crop region vinaceous-pink (dark 

 purplish vinaceous in true G. martinica) ; belly and under tail coverts paler., 

 more buffy, less brownish or clay color.

Remarks. — If the large series of G. martinica I have examined in this con- 

 nection is properly sexed by the collectors, and I see no reason why it is 

 not so, then the sexes in this quail dove do not differ in color. The plain 

 dark colored examples are all marked "young" and appear to be such. 

 These had been supposed to be adult females, and the species was given 

 by Salvadori in Cat. Birds, Brit. Mus., Vol. XXI, as having the same dif- 

 ference in color between the sexes as Geotrygon montana. 



I have seen no skins from Martinique, but have examined a number 

 from both Dominica and Sta. Lucia which are precisely similar. The one 

 specimen from Guadeloupe differs so much from these that the question is 

 simply whether it shall be called a species or subspecies ; the latter course 

 perhaps better expresses its relationship. 



The present subdivision of the species, then, restricts true G. martinica to 

 Sta. Lucia, Martinique, and Dominica and makes the bird of Guadeloupe a 

 well-marked island form. Specimens from Guadeloupe appear to be very 

 rare in collections and when Salvadori wrote Vol. XXI. he could only con 

 jecture that the bird pro))ab]y occurred there.
