Birds from these islands seem inseparable from C. caniveti 

 from the mainland. The rectrices, however, seem unusually 

 broad, the central pair not so short, so that the tail is not so 

 deeply forked as in C. caniveti. These points seem hardly 

 constant enough to justify the separation of these Bay-Island 

 birds. There is a marked contrast between them and the 

 Cozumel-Island bird as regards the elongation of the outer 

 rectrices.

These birds are exceedingly like C. auriceps, and I have 

 long hesitated whether to keep them separate or not. The 

 nncertainty as to the true domicile of C. auriceps added to 

 my doubts. This point has now been settled, as Mr. Smithes 

 collection from the State of Guerrero contains a single ex- 

 ample of the ti'ue C. auriceps, which, though not quite adult, 

 is sufficiently advanced in plumage to leave no room for 

 doubt as to its name. 



It now appears that C. forficatus can generally be distin- 

 guished by its greener, less golden ci'own, and rather broader 

 lateral rectrices. 



Some of the specimens from Holbox Island have the outer 

 rectrices much shorter than others, and are thus hardly to 

 be separated from the mainland C. caniveti. Mr. Devis's 

 specimen, called by me C. caniveti, is a fragment, and most 

 of the tail-feathers are wanting.
