116 Mr. P. R. Lowe on the Birds of 
(‘ Ibis,’ 1904, p. 572), says: “ This species varies considerably 
in plumage and also in the coloration of the bill. 
I have carefully examined a large series of specimens from 
Puerto Rico, St. Thomas, St. Croix, St. Kitts, Dominica, 
Grenada, &c., some of which I shot myself, and have rather 
reluctantly come to the conclusion that there are no sufficient 
grounds on which to separate them from the Jamaican form. 
Dr. Hartert has remarked on the much richer and darker 
colour of the birds from St. Thomas ; and my opinion is that 
the squamate markings on the breasts of specimens, more 
especially females, in the series, are distinctly coarser, darker, 
and more noticeable, but further than thus it is difficult to go. 
As regards examples from the Cayman Islands, Mr. Ridgway 
separates them as C. passerina insularis, describing them as 
very similar to C. bahamensis, “but larger, and with the 
basal half (or more) of the bill distinctiy orange or yel- 
lowish.” I have examined specimens collected on these 
islands by Dr. Bowdler Sharpe, Mr. M. J. Nicoll, and myself, 
and beyond the fact that they are slightly paler above than 
specimens of (. passerina from Jamaica, I am unable to find 
any differences. In this I am in agreement with Mr. Cory 
(‘ Birds of West Indies,’ 1889, p. 297) and Mr. Nicoll (¢ Ibis,’ 
1904, p. 585). 
The Ground-Doves of Cuba have been lately distinguished 
Yas C. aflavida (Palm. & Riley, P. Biol. Soc. Wash. xv. p. 35). 
Seven or eight specimens in the British Museum have a 
deeper and somewhat rusty tinge below, probably due to 
stains from iron-impregnated soil. 
C. terrestris and C. pallescens both appear to be good 
species. In a splendid series of the former bird in the 
British Museum, the males are of a very uniform dull vina- 
ceous tint beneath, both over the breast and on the flanks 
and abdomen ; the females are also of a uniform ashy-brown 
tint or almost mouse-colour beneath. The Javender-blue 
patch on the head and neck in the male birds is conspi- 
cuously bright and not obscured by brown. It is, indeed, 
a simple matter to pick out a Floridan bird, especially a 
female, out of a very large series from all parts,
