larger bird. As iu all Aviug-spotted coutinental species 

 (except C. luteula), tlie wing-spot in C. mexicana is a variable 

 qnantity, and is nothing like so conspicuous as in the insular 

 races of the Greater Antilles. In C. mexicana and its allies 

 it is sometimes liable to be nearly concealed by the primary 

 wing-coverts. In six examples from Nicaragua it was hardly 

 visible. It is worthy of note that although several large 

 collections of birds have been made iu Yucatan, none con- 

 tained any species of the* genus Careba, so that we may 

 conclude that the genus is not represented there. I have 

 also been unsuccessful in finding any record of a repre- 

 sentative from British Honduras or Honduras proper. 

 As regards British Honduras^ the nature of the country is 

 such as to cause no surprise at the absence of any species of 

 the genus, the Flora generally being quite unsuitable, but 

 the conspicuous absence of all records from Honduras proper 

 seems very curious. While on the eastern coast of Mexico 

 at Tampico and also further south at Coatzacoalcos I failed 

 to secure or to see a single specimen of C. mexicana, although 

 my excursions in search of birds took me in all directions 

 to distances of more than twenty miles from both these 

 localities. This was in the early spring, during three 

 consecutive yearly visits.
