This species, if distinct from the preceding, is barely Bepa 

 ble. Mr. Cabanis seems to have been donbtfnl about if. 

 he says, "The difference may depend on season and on fresh 

 moulting." A specimen from Mexico, which is anqnestionably 

 M. lavjrencii, has the gray coloring <>t' the thro 

 over the breast, this is also the case in several examples fr"m 

 Guatemala; some of the specimens from Ooeta 1^ I agree in 

 this character, while others have this color confined t.. the 

 throat; in labelling them I have made this the point of differ 

 ence; in those with the gray i *ted t<> the throat and <-'>n- 

 sidered to be M. ntgrieapiUus, the crowns seem to l"- of s little 

 deeper brown, but this last character i- not v. rv decided.
