different geographic areas) except in the case of specimens from northeastern Mexico 

 and the Rio Grande Valley of Texas, which are decidedly larger, except bill and feet. 

 The status of specimens from northeastern South America puzzles me exceedingly, 

 and I have not a sufficient series of specimens to enable me to determine their status 

 satisfactorily. On the whole, they seem to resemble Central American specimens 

 more than those from southern Brazil, etc., yet some specimens (notably the single 

 example from the island of Grenada and several from Tobago and Trinidad) I can 

 not distinguish from true T. melancholicus, being quite as dark in coloration as any 

 of the latter. Specimens from Yucatan are almost invariably clear yellowish olive- 

 green on the back, etc., and closely resemble in coloration T. m. couchii; on the other 

 hand, none of the specimens from the island of Cozumel are like those from the 

 mainland of Yucatan, all (in the series before me) having more gray than olive-green 

 above. On the whole, I am not satisfied with the arrangement here presented, but, 

 owing to lack of both time and material, must leave the subject to some one else for 

 more detailed treatment.
