M. Sally's recent collections contain a single specimen of this curi- 

 ous little bird, which was obtained in the neighbourhood of S. An- 

 dres Tuxtla. There is no doubt about its belonging to the Tyran- 

 nidce, but the form of the bill appears to be quite different from 

 that of any bird hitherto recognized as of that family, and to require 

 a new generic appellation. I have therefore called it Camptostoma 

 from the arched form of the culmen. The specific name imberbe 

 refers to the entire absence of rictal bristles. I consider Tyrannulus 

 to be perhaps its nearest-allied generic form, from which, however, 

 it may be at once distinguished by the peculiar depth and compres- 

 sion of the bill. Dr. Hartlaub's Ornithion inerme belongs, I suspect, 

 to this same section of Tyrannidce.

Adult specimens of this bird in M. Salle's recently received col- 

 lections from Jalapa seem to be quite the same as Temminck's plate. 

 I believe the bird called Cyanocitta Jloridana in my former list to 

 have been the young of this species.

The Guatimalan species (C. pumilo) which is figured as " C. 

 nanus V in the 'Contributions' (1849, pi. 33) is perfectly distinct 

 from the present bird, and Prince Bonaparte has done quite right in 

 keeping them apart. In the C. nanus the throat is silvery whitish- 

 blue, whereas in C, pumilo it is quite dark, almost black.
