tlie type and a secoud sijeciiueii. Count ljerli'j)sch and Dr. Hartert (/.'•.) liave 

 alread)' noticed that some specimens of C. aerughiosus collected by Mr. (^herrie in 

 the Orinoco Region (especially from Ciudad Bolivar and Altagracia, and in Margarita 

 Island) ajijiroach those of ('. arubi-ioiig. I think that in some cases it will be 

 difiicnlt to distinguish the two forms, although the cheeks and throat of C.ancbensis 

 ajjpear somewhat paler. Among the specimens of C. aeriujinosus, the more western, 

 among those belonging to the Tring Museum, is one from Valencia. 



From Antioquia, in Colombia, the Tring Museum possesses one specimen 

 purchased from Mr. Dunstall ; it has been kept in confinement, and differs from 

 all the specimens of ('. acriiginosm in having the cheeks and throat very dark 

 Wown, the feathers of the cheeks distinctly of a scale-like ai)pearance ; besides, it 

 aas a very narrow yellow line bordering the lower eyelid. A similar specimen, but 

 of a darker tinge on the throat and cheeks, is ke])t alive by Dr. Festa, of Turin. It 

 appears to me that the latter, the Antioquiau one, and probably all the Colombian 

 ones, belong to a form distinct from the one from Venezuela and British (iuiana ; 

 the Colombian ftu'm, I think, must stand as ('.chnjaophrys Sw., figured by Souance, 

 Icon. Vinr. \A. \\. 



I am not acquainted with C. tortuyeusis Cory, l-'i<dd Mas. of Nat. Hint.., Orit. i. 

 p. 2X!0 (191)0), from Tortuga Island, similar to ('. ai'iuyiiiosus, but with the sides 

 of the head more orange }ellow, and with the lower part of the cheeks paler, as in 

 C. urudi'ji «)■■<. 



In conclusinn, instead of the four species admitted in th(! Cutnliiijae of /i'li/.t 

 in Is'.ij, we have now eight * : C. cactorum, from S.l<]. Brazil, ('. .rantlioyt'iiius, from 

 Bonaire, <'. ]iertina.r, Uo\n ('nviuyMt and Saint Thoma<, C. oculnri.'t, from Panama, 

 ('. aeiiiyiiiogit.s, from British (iuiana and Venezuela, ('. uri(//('/ix/',i, from Arnba, 

 C. tortugeiMis, from Tortuga Island, anil ('. cliri/soiiluijs, Irom (.'ulomliia. 



* In the opinion of tlie Editors, altliougli tliey agree as to tbere being eiglil fu:ni4, ull of tlie above 

 are sub.fpsties of one species ; and 8o it would be st.angc if some specimens did not sliow intcrgradalioua 

 in plutnage.
