* Bonaparte incidentally mentions this genus as " Trypanocorax (Kaup) ;" 

 and he also alludes to a genus Frugilegus of Lesson. Neither of these generic 

 names have I been able to find in the published works of these authors, although 

 the latter is adopted by Mr. G. E. Gray in the ' Handlist ' as a section of the 

 genus Corvns. Sundevall also quotes Kaup as the author of the generic name ; 

 but until the exact place of publication is discovered, the Swedish professor 

 must have the credit of establishing the genus, to which he was the first to 

 assign peculiar characters.
