This form is the representative of the foregoing one in Lower Guinea, where 

 it occurs from Fernando To and Kameruu to the Lower Congo. The occurrence at 

 Aguapim on the Gold Coast is surely stated erroneously, while the birds collected 

 Iiy Thompson, and recorded as coming from the Niger, in the Cat. Birds vol. xix. 

 p. 443, were collected in the Kamerun, as will be found in Thompson's Narrative 

 of the Siyer Expedition. 



Tiiis bird cannot be called Taraciis meriani. lu his paper, " Ueber eine nene 

 Art von Tottracus," which appeared in Bericht der Verhandl. Naturf. Gesellsch. 

 Basel, i)robably in January 1851, Riippell described Turacus persa from specimens 

 which had been sent to the Basel Museum from the Gold (Joast, probably by the 

 missionary Riis from Aguapim, as a new species under the name Turacus meriani, 

 believing the red-crested form to be the true Turacus persa : (" Man unterscheidet 

 ihn (persa) leicht dnrch die scharjachroten Spitzen seines etwas comprimierten 

 Federschopfes "). 



He gave here the characters which distinguish the green-crested Turacus from 

 the Gold Coast from the Senegambian T. bujjoni. 



Shortly afterwards Riippell found out his mistake, and published another 

 jjaper on the same subject in Wiegmann's Archie ficr yaturijeschichte, vol. xvii. 

 (1851) ]). 316, whicli appeared iu the summer or in October 1851, and which he 

 called a correction of the first article (" Als Berichtigung eines Anfsatzes von mir 

 iiber den gleichen (Jegeustand, abgedruckt in dem 9ten Berichte der Easier 

 naturforschenden Gesellschaft "j. In this article now, without mentioning the 

 mistake he has made before, Riippell simply applies the name "meriani" to a 

 totally different species — i.e. the red-crested one I 



It is quite obvious that such a proceeding is not allowed by the rules of 

 nomenclature. Kiippeirs name is a synonym to T. persa L., and the red-crested 

 bird has therefore to stand as Turacus verreauxi Schleg. 1854.
