same as G. albifacies, and that it is really a distinct and valid 

 species, of which they give a figure and make the correction 

 {Exot. Ornith. Oct., 186S, Part viii., p. 123, pi. lxii.i. 



Judging from the last plate and description, my species Beems 

 to be G. chiriquensis, which name, of course, must have priority. 



I was, in fact, misled in conferring a synonym on a spec 

 since found to have a claim to a prior name, but the information 

 then available justified the course which I adopted. 



In the JProc. of the Phil. Acad, of Sci. } l s, '>-\ p. L08, I do- 

 scribed a Geotrygon from Panama, viz., G. aXbw< nt, r. 



A reviewer in the Ibis, 1866, p. 120, notices it as follows: 

 "The close proximity of Panama to Chiriqui makes us Buspect 

 it may ultimately prove identical with G. chiriquensis^ though 

 there are discrepancies in the descriptions. Still, when such 

 delicate bronze colors have to bespoken of, it is hardly likely 

 that two writers should call the same tint by the same as 

 The Chiriqui bird is somewhat larger (wings 5.9 inches insl 

 of 5.5 inches) ; but not having specimens of either before 08, we 

 cannot decide the point." With both species before me, I 

 now state explicitly that they have but few points of resemblance : 

 G. albiventer is very much smaller (about the >f G. rnoru 



tana), has no grayish-blue on the head, and although the colors 

 of the upper plumage are somewhat alike, yel they are of 

 quite different shades; below they are totally unlike, instead of 

 the breast being dark castaneous as in chirigtu mis, in my sp 

 it is pale lilac, and in the latter the belly and under tail 

 are pure white, which in the former are of a rather light dull 



cinnamon. 

 When I first saw the suggestion of tlv probable identity of the 



two species, it did not seem to me that the argum 



to sustain it had much force, as they were b 



jecture.
