Page 225: The specimen described as the "adult female (?)" of 

 Vireolanius melitophrys, but which I have suggested, in footnote c, 

 may represent " a paler arid region (table-land) form," has been dupli- 

 cated by an adult female collected at Huitzilac, State of Morelos, by 

 Messrs. Nelson and Goldman, of the U. S. Biological Survey. Mr. 

 Nelson is quite sure these two specimens, together with a young male 

 from Huitzilac, represent a previously undescribed form, which he 

 has described as — 



VIREOLANIUS MELITOPHRYS GOLDMANI Nelson. 

 GOLSUAN'S SHRIEE-VIKEO. 



Similar to Vireolanius melitophrys melitophrys, but larger, with 

 shorter bill; coloration paler and duller, the pileum and hindneck light 

 brownish gray (nearly mouse gray) merging gradually into the olive- 

 green of the back, instead of clear slate-gray, abruptly defined poste- 

 riorly; broad postocular stripe slate color instead of black; black 

 submalar streak heavier; band across chest paler chestnut-rufous, not 

 continued along sides, which are pale cinnamon-buffy anteriorly, pass- 

 ing into olive-gray on flanks. 



Yo^mg male. — Pileum and hindneck light brownish gray, tinged 

 with cinnamon ; superciliary stripe light ochraceous instead of yellow; 

 under parts of body (except narrow median stripe of whitish) dull buff 

 or pale cinnamon-buff. (Otherwise much like adult female.)
