Neither time nor space will allow me, on this occasion, to re- 

 view the whole catalogue of some 80,000 names, hut the follow- 

 ing list of bird-genera, picked out of the letter E alone, will give 

 an idea of the deficiences : Eleopiciis^ Elminia^ Enipidivora^ 

 Entomiza^ Eomelpusa^ Eophotia^ Eparnetes^ Epherusa., 

 Ephippiorhynchus^ Epitelarus^ Erator^ Eremo?nela, Ericor- 

 nis^ Eridora^ Erodiscus^ Erythi-a^ Erythrcena^ Erythrauchoe- 

 nuy Erythrocerczis, Erythroena^ Erythrolaima, Erythroner- 

 pes^ Erythropitta^ Eiythropsar^ Erythrotreron^ Euca?npo- 

 phagUy Eiicapripodiis^ Eiichloridia., Eucichla^ Eucne7nidia^ 

 Eticycla^ Eudacuis^ Eiidyptila^ Eiietheia^ Euhierax^ Eu- 

 labcea^ Euliga^ Eulopogon. Eunetta^ Euodice. Euphagus^ 

 Eitptilosiis^ E?/rycerc?(S^ Euryzona^ Ensphenu7-a^ Ettstrinx^ 

 Euthojiyx^ Eittolniaetiis^ Eutrygon^ Exetastes, ExocJiocichla. 

 The list is by no means complete and diligent search might 

 add several more names. 



The high standard of Agassiz's ' Nomenclator ' resulted from 

 his collaboration with prominent ornithologists. He had his 

 proofs i-evised by men like Bonaparte, G. R. Gray, and Strick- 

 land, who, by allowing their names to be printed on the title- 

 pages, partook of the responsibility. The same perfection might 

 have been reached by Dr. Scudder, if he had followed a similar 

 course. 



Nevertheless, the work will be of very great use to the work- 

 ing ornithologist, who will only have to be careful to remember 

 that he has not got a complete list of all the existing names. 



A look through its pages shows the necessity of several changes 

 in our nomenclature. 



In the first place, I find that the name Sthenehis^ which I 

 applied, in 1882, to the Black-necked Swan from South America, 

 was preoccupied. It consequently requires a new one, and I 

 propose in future to call the species Sthenelides mcla^icorypha. 



Etidocinnis Wagler, 1833, w411 not hold good as the genus-name 

 for the White and Scarlet Ibises, as there is a lepidoptei^ous insect 

 called '•'' Eiidocima Billb. 1820." It is very doubtfvd what name 

 will have to replace it. Guara was bestowed upon the Scarlet 

 Ibis by Reichenbach in 1851, and Leucibis at the same time upon 

 the White Ibis. But in his 'List of Genera' of 1855 G. R, Gra\-
