CHLOEOlSrEEPES. 407 



Yucatan, the next species entirely takes it place ; and though the two birds are evidently 

 closely allied, they can nearly always be distinguished with certainty. A male from 

 Atoyac, however, has the red over the eye carried forward in a very narrow line to the 

 base of the bill; the bars of the breast are, however, those of C. ceruginosus. In 

 Western Mexico two other birds, C. auricularis and C. godinanl, take its place — one in 

 the Sierra Madre del Sur, and the other in the Sierras of the State of Jalisco. 



C. ceruginosus may always be recognized by the red band on the side of the head 

 becoming evanescent over the eye, and by the hastate character of the transverse light 

 bands on the abdomen. 



Some time elapsed before Lichtenstein's name for this species became established. 

 In the first place, it is very probably the Pious poliocephalus of Lichtenstein's list of 

 Deppe and Schiede's duplicates ^, a name unaccompanied by any description. It is 

 certainly the Chleronerpes ceruginosus of Lichtenstein's ' Nomenclator,' as testified by the 

 specimens now in the Berlin Museum. This name was indirectly established by Gray, 

 who first figured the bird in the ' Genera of Birds ' as Swainson's C. rubiginosus, but in 

 the Appendix applied to it the name the bird now bears. Mr. Sclater for some time 

 called it C. yucatanensis ^ ^"j but eventually recognized its correct name ^. 



C. ceruginosus is doubtless a resident species where it occurs. We have records of its 

 presence at various places nearly throughout the year.
