600 MESSRS. SCLATER AND SALVIN ON PERUVIAN BIRDS. [ Nov. 25, 
Oés. Similis O. enanthoidi, sed tectricibus alarum non rufo 
marginatis, dorso cinereo, et rectricis utrinque externze margine albo 
differt. 
Mr. Whitely obtained his examples of this Ochthoeca, which we 
at first took for O. enanthoides, at Pitumarca, in April and June last. 
Another nearly allied species is O. fumicolor, Sclater, of New 
Granada and Ecuador. Sclater has skins of the true O. wnanthoides 
collected by Mr. David Forbes in Bolivia. 
In the present bird the fourth primary is slightly longer than the 
third and fifth, and largest. The tail is nearly square, the external 
rectrices being only slightly shorter than the middle pair,

Two examples of this Pigeon from Pitumarca. It must be care- 
fully distinguished from its naked-eyed allies, C. picazuro and C. 
gymnophthalma, with which Bonaparte and other writers have con- 
founded it. There are specimens of it in the Paris Museum, obtained 
in Sicasica, Bolivia, by d’Orbigny.
