This and the following two species are remarkable for 

 exhibiting a more or less defined and centrally disposed 

 patch of white on the otherwise nearly black throat. 



In C. martinicana the coloration bears evidence of the 

 effects of the humidity obtaining in the densely forested and 

 mountainous islands in which it is met Avith. 



The pileum, mantle, &c. are dark sooty black as compared 

 with a sooty slate coloration in C. barbadensis and C. uro- 

 jnjgialis. 



The rump is olive-green and more restricted than in its 

 nearest allies, in which the coloration is olive yellowish. 



The eye-stripe in C. martinicana does not extend so far. 

 back as in C. barbadensis or C. uropygialis ; the underparts 

 are more tinged with olive, the yellow coloration being 

 duller than in C. barbadensis, and nothing like so clear and 

 bright as in C. uropygialis. 



In C. martinicana the malar stripe of grey is absent, and 

 the white on the throat is larger and more defined than in 

 either of the two other allies.

In C barbadensis the coloration is lighter above and 

 clearer and brighter yellow below than in C. martinicana. 

 The rump is olive-yellow instead of olive-green ; the white 

 of the throat-patch is smaller and the lateral rectrices are 

 broadly tipped with white on both webs (Antillean charac- 

 teristic). There is a smaller stripe of grey not seen in 

 C. martinicana.
