At the jjlace quoted Boddaert gives the following: "PI. IfJO. Tourterelle dii

Linne's Colamba ufra wa.s fonnded npon Brisson's bird. The acceptance of 

 Boddaert's work necessitates the above alterations.

should ri'place Chionis Forster, 1788. 



This is a most curious instance of jierversity in the choice of generic names. 

 Forster in the Enchiridion 1788 gave diagnoses of genera only: eighty-one names 

 iu all, of which only three were new. Of even date Graelin proposed new generic 

 names for two of tliese, with good definitions and sjiecies cited. Ijegally both of 

 Gmelin's genera have priority, but one lias been accepted, the other rejected, though 

 the conditions are absolutely identical iu each case. Moreover, in this case there 

 is a prior Chion (Scopoli, Intro. Hist. Sat. p. 398, 1777), whicli may be considered 

 by some authorities to preoccupy Chionis. 



1 am indebted to Mr. Tom Iredale for much help witli the foregoing work.
