Hans von Berlepsch on the Genus Cyclorhis. ^7 



being in some of them more strongly suffused with ochra- 

 ceous than in others *. 



I have examined a specimen in the Vienna Museum col- 

 lected near Goiaz ( (^ , coll. 12th August, 1823) by Joh. Natterer 

 (not distinguished by von Pelzeln from his C. wiedi),dinA. have 

 found it to be quite identical with my Bahia skins of C. 

 cearensis. 



From C. yuianensis, C. cearensis differs in its dusky legs, 

 stouter, higher bill, and the more restricted plumbeous 

 mark of the under mandible ; in C. guianensis nearly the 

 whole of the under mandible being plumbeous, while in 

 C. cearensis the plumbeous colour extends halfway or two- 

 thirds from the base. Further, C. cearensis has always a 

 brownish cap, never of so clear a plumbeous grey as in C. 

 (juianensis. The yellow of the breast and sides is usually 

 much paler and more restricted, the belly purer white to a 

 great extent, and ivithout any greyish cast. 



The synonymy of this species will stand as follows : —

-f?. Cyclorhis ochrocephala, Tsch. 



Tschudi evidently confounded several species under the 

 above name when he stated that his C. ochrocephala inhabits 

 " Brasil. merid., Buenos Ayres, Bolivia, and Peru^'f ; but his 



* Although Prof. Baird did mention the buff tinge as a distinguishing 

 cliaracter of C. cearensis, he would probably lay gi-eater stress on the fact 

 that in C, cearensis the greyish tinge of C. yuianensis is altogether 

 absent. 



t The bii'd from Bolivia would be C. viridis (Vieill.), and that from 

 Peru C. guianensis (Gmel.).
