CHLORONERPES. 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. wruginosus. In 
Western Mexico two other birds, C. auricularis and C. godmani, take its place—one in 
the Sierra Madre del Sur, and the other in the Sierras of the State of Jalisco. 
C. eruginosus 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 Picus poliocephalus of Lichtenstein’s list of 
Deppe and Schiede’s duplicates!, a name unaccompanied by any description. It is 
certainly the Chloronerpes wruginosus 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. rudiginosus, but in 
the Appendix applied to it the name the bird now bears. Mr. Sclater for some time 
called it C. yucatanensis ® 1°, but eventually recognized its correct name>, 
C. eruginosus is doubtless a resident species where it occurs. We have records of its 
presence at various places nearly throughout the year.
