Obs. A. derbiano proximus, sed statura minore, macula 

 nucbali et plaga suboculari cseruleis absentibus distinguendus. 

 This is the first species of this upland gienus we have seen 

 from Guiana. Mr. Whitely has sent us a single specimen of 

 it, marked as a male. It is most like A. derbianus, but 

 seems certainly distinct from that species. The bill is coloured 

 much as in A. derbianus; but the white basal line is not 

 so prominent or so clearly defined. The tail, as in the 

 allied species, has the two central feathers alone tipped 

 with chestnut ; but the blue nuchal patch is absent, as well 

 as that beneath the eye. 



CoNURus EGREGius, Sclatcr. 



In ' The Ibis' for last year (1881, p. 130, pi. 4) Mr. Sclater 

 described and figured a species of Conurus from specimens the 

 locality of which was doubtfully stated to be Demerara. All 

 doubt on this point is now removed by the occurrence in 

 Mr. Whitely's collection of four specimens of it obtained by 

 him in the Merume Mountains. Some slight variation is to
