these without any doubt whatever. The birds named were 
Polytmus (Campylopterus) cecilie, Mellisuga (Panoplites) 
judith, Mellisuga (Cynanthus) salvadorii, and Mellisuga (Eri- 
ocnemis) ridolfit. The first of these I have not seen, as it 
is in the Museum of Turin ; but on writing to Count Salva- 
dori, he assures me that it is only a female of Campylopterus 
lazulus; and I believe this identification to be perfectly cor- 
rect. ‘The second is 
Metuisuea (PANOPLITES) JUDITH. 
Mellisuga judith, Benv. Ann. del R. Mus. Florent. 1865, 
p- 208, sp. 11. 
- This bird proves to be the Panoplites flavescens, with which 
Signor Benvenuti had compared it; and I cannot perceive 
that the differences given by him were in any way of suffi- 
cient consequence to cause him to give the specimen a new 
name. It is a male, in adult plumage; and the name of M. 
judith must become a synonym of P. flavescens. 
The third was named 
MeE.uisuea (CYNANTHUS) SALVADORII. 
Mellisuga salvadorii, Benv. Ann. del R. Mus. Floren. 1865, 
p. 204. 
The type of this so-called species is an adult female of Cy- 
nanthus cyanurus in the ordinary state of plumage, such as 
is commonly observed in all the specimens of this sex com- 
ing from Bogota. There is nothing to distinguish it as dis- 
tinct; and the name given by Sig. Benvenuti must become a 
synonym. 
The last described is 
Me.uisuea (HRIOCNEMIS) RIDOLFII. 
Mellisuga ridolfi, Benv. Ann. del R. Mus. 1865, p. 205. 
This bird, on examination, proves also to be a female of a 
well-known species, Hriocnemis vestita, one of the commonest 
and best-known among Humming-birds. The name ridolfii 
must sink into a synonym. 
It is a pity that before naming these birds as distinct, 
Signor Benvenuti had not followed the advice given -to him 
by M. Sallé in the letter published in his article, and sent
