It appears to us to be quite unjustifiable (see our remarks, 
‘Ibis,’ 1904, p. 154). 
43, Oberholser on a new Humming-bird. 
[Description of a new Genus and Species of Trochilide. By Harry C. 
Oberholser. Proc. Biol. Soc. Washington, xviii. p. 162. | 
Aeronympha prosantis (gen. et sp. nov.) is based on a 
single “ Bogota” skin in the Field-Columbian Museum 
at Chicago. The form “seems most nearly to resemble 
Zodalia.” 
44, Ribeiro on the Birds of the Serra Itatiaya, Brazil. 
[ Vertebrados do Itatiaya (Peisces, Serpentes, Saurios, Aves e Mammi- 
feros) resultados do Sr. Carlos Mereira, Assistente da Seccao de Zoologia 
do Museu Nacional. Por Alippio de Miranda Ribeiro. Arch. Mus. Nac. 
do Rio de Janeiro, vol. xiii. (1906). ] 
Sr. Ribeiro has kindly sent us a copy of his report on the 
Vertebrates collected by Sr. Mereira on the Serra de Itatiaya, 
between the provinces of Rio and Minas, which is said to rise 
to a height of 10,000 feet, and is therefore of much interest. 
The birds enumerated are 52 in number and are mostly of 
well-known species. Two, however, are described as new— 
Synallaxis mereire and Musciphaga (scr. Muscivora ?) obsoleta. 
The most interesting species is Scytalopus sylvestris, which is 
figured. But is it really S. sylvestris? It is more likely 
to be S. indigoticus. S. sylvestris is a Peruvian species, 
which would probably not occur in S.E. Brazil. It would 
have been better to give the elevation on the Serra at which 
each species was met with. 
45. Ridgway on new Genera of American Birds. 
[Descriptions of some new Genera of Tyrannide, Pipride, and Co- 
tingide. By R. Ridgway. Proc. Biol. Soc. Wash. xviii. p. 207 
(1906). } 
Mr. Ridgway proposes sixteen new generic terms in the 
three above-named families :—Aphanotriccus (type Myiobius 
capitals), Terenotriccus (Myiobius fulvigularis), Myiotriccus 
(Tyrannula phenicura), Atalotriccus (Colopterus pilaris),
