Vol i.907 IV 1 Stone, Changes in Generic Names of American Birds. 197 



Reich, has been used for this bird and its allies and Coeligena 

 for 0. clemencice. Replacing Reichenbach's name with Coeligena, 

 we leave 0. clemencice without a generic appellation and I propose 

 Cyanolaemus, 1 type Ornismyia clemencice Lesson. 



V. Error in selecting the Type. 



Ceophixeus Cab. 1862, becomes Phlceotomus Cab. & Heine, 

 1863. — The Check-List cites Picus pileatus L. as the type of Ceo- 

 phlceus Cab. but in the original publication, J. f. O., 1862, p. 176, 

 Picus lineatus L. is explicitly given as the type. Therefore if we 

 regard these two species as generically distinct, we must adopt a 

 new name for Picus pileatus L. Hargitt, in the British Museum 

 Catalogue, Vol. XVIII, adopts Dryotomus from Swainson, Class. 

 Birds, II, p. 308, but, as Dr. J. A. Allen has pointed out to me, 

 this name first appeared in the Fauna Bor. Amer., II, p. 301, 

 where Picus martins L. is given as the type, so that it becomes a 

 synonym of Picus L. Phlceotomus Cab. &. Heine, Mus. Hein., 

 IV, p. 102, 1863, based exclusively upon Picus pileatus L., is, how- 

 ever, available. 



VI. Changes due to the First Species Rule. 



In order to definitely fix the types of various composite genera 

 of older authors, the revised Code of Nomenclature of the A. O. U., 

 which has been adopted but not yet published, provides that where 

 no type is indicated in the original publication and where none is 

 implied by the rule of tautonomy, the first species mentioned by the 

 original author shall be taken as the type, except in the case of 

 Linnsean genera where the commonly accepted species shall remain 

 the type. After the changes above indicated have been made we 

 find that there are in the Check-List 121 composite genera with no 

 indication of type species. In 93 of these the commonly accepted 

 type is the first species, and of the others 16 are Linnsean genera. 

 Selecting the first species in each of the remaining twelve genera 

 as the type we shall have to make the following changes. 



Cyclorrhynchus Kaup, 1829, becomes Phaleris Temm. 1820. 



Phaleris Temm. 1820, becomes Alcella nom. nov. 



1 Kvav«os blue, Xat(ios throat.
