XXXIII. — Remarks on the Species of the Genus Cyclorhis. 

 By P. L. Sclater. 



(Plate X.) 



Having been obliged during the preparation of the first 

 volume of 'Argentine Ornithology* to come to some con- 

 clusions as to the correct names of the two Argentine species 

 of Cyclorhis, I have been led to examine carefully the series 

 of specimens of this genus in the National Collection, which, 

 since they were catalogued by Dr. Gadow (Cat. B. viii. pp. 316 

 et seqq.) in 1883, have received considerable additions from 

 the collection of Messrs. Salvin and Godman and my own. 

 As, with the aid of this increased number of specimens, I 

 have come to rather different conclusions as to the best mode 

 of arranging the species of the genus in natural order, I 

 venture to put forward my views on this subject, and at the 

 same time to point out the characters of what I believe to be 

 a new and interesting member of the group.
