Species of the Genus Cyclorhis. 323 



5. Cyclorhis GuiANENsis (Gm.). 



All the specimens of Cyclorhis I have seen from Guiana, 

 Cayenne, and Upper and Lower Amazonia may be referred 

 to C guianensis, which has a grey belly, a greenish-yellow 

 throat, and narrow red superciliaries. 



6. Cyclorhis albiventris, Scl. 



This form, which is prevalent in S.E. Brazil from Pernam- 

 bueo to Bahia, comes in some cases, it must be admitted, 

 very near to C. guianensis, but is recognizable by its white 

 belly and the rufescent tinge of the crown, which in typical 

 C. guianensis is of a pure grey. C. cearensis, Baird, Rev. 

 A. B. p. 391, is stated to have a ''decided buff tinge ^' on 

 the belly, and cannot therefore, I think, be the same as C. 

 albiventris, as Graf v. Berlepsch seems to regard it. 



7. Cyclorhis ochrocephala, Tsch. 



Tschudi's types of this form, which is at once distinguish- 

 able from the six previously noticed by the uniform reddish 

 bill, without any trace of the dark plumbeous spot on the 

 lower mandible, were from South Brazil, where the species is 

 found in the provinces of Rio, San Paulo, and Rio Grande 

 do Sul [cf. v. Berlepsch, Zeitschr. £. d. g. Orn. 1885, p. 116). 

 After examining the series now in the British Museum, T 

 have come to the conclusion that the Argentine species 

 hitherto usually called (but erroneously, I believe) C viridis, 

 may be safely referred to it also. Some of the Argentine 

 specimens can barely be distinguished from skins from Rio, 

 though, as a general rule, the southern bird has a brighter 

 yellow on the breast and not so much rufous tinge on the 

 crown. C. wiedi of Velzeln (Orn. Bras. p. 74), of Parana, 

 is also barely separable. 



8. Cyclorhis altirostris, Salv. Ibis, 1880, p. 382. 



As has been pointed out by Graf v. Berlepsch (Zeitschr. 

 f. d. g. Orn. 1885, p. 116), this is probably the Habia verde of 

 Azores, and, if so, ought to have the name " viridis " 

 of Vieillot. But, as this is by no means certain, and a 

 quite different species has been hitherto usually recognized
