coloration above and below, and in lacking the liglit edges to 

 tlie secondary wing-feathers. 



When we consider the recent volcanic nature, greater 

 humidity, and greater extent of dense and almost primaeval 

 forests which characterise the islands of Dominica and 

 Guadeloupe, and to a less extent those of Montserrat, 

 Nevis, and St. Kitts, the darker and richer coloration of 

 these birds is not surprising. 



Mr. Cory (Cat. W.I. Birds, 1892, p. 155) considers that 

 Marie Galante and Desirade are inhabited by C. bartolemica, 

 that is to say by the paler form described by Sparmann, 

 which again is not surprising, as these islands consist of 

 pure limestone formations similar to those of Antigua and 

 Barbuda. 



Probably the part of Guadeloupe known as Grand Terre 

 and the small island of Petite Terre, which are also of the 

 same limestone formations, support this pale race. 



It is to be noted that in nearly every example of the 

 nineteen specimens examined from Dominica the white 

 eye-stripe stops short just behind or just above the eye (as 

 in C. bartolemica) , and that this is better noticed when the 

 white frontal band is absent. In thirteen out of nineteen 

 Dominican birds this frontal band was present. Birds from 

 St. Kitts, Montserrat, Antigua, Barbuda, Anguilla, and 

 Eustatius all shew it, so that neither the eye-stripe nor 

 the frontal band can be considered as of any value in dis- 

 tinguishing the two races.
