Tue specimen from which the accompanying drawing is taken was procured in Paris; it had a label at- tached, on which was the word ‘‘ Mezique,” and this was all the information I could obtain respecting it. I have since seen other examples in a collection sent from Carthagena, whence I am led to infer that the Caraccas, the Spanish Main, and the southern portions of Mexico are its true habitat. In its colour it is so closely allied to the Trogon melanurus, that it might readily be mistaken for that species ; but it is so much larger in all its measurements, that I feel confident it is specifically distinct, and have named it accordingly.
