A northern form of E. cristata, to which it is very closely allied, but may be recog- 

 nized by the darker tint of the grey head, and by the absence of the silky crest present 

 in the allied species. E. spodocephala was first described by Bonaparte from specimens 

 procured by Delattre in Nicaragua, whence we have an example and have seen others. 

 It was then traced to Guatemala, where, however, we only obtained a single specimen, 

 out of a collection made by the late Don Vicente Constancia, and we are uncertain in 

 what part of the country it was shot. In Yucatan and in British Honduras it would 

 appear to be more abundant, as Mr. Gaumer obtained several specimens in the former 

 country, some of which have come into our possession through M, Boucard ^. South- 

 wards of Nicaragua it is found but rarely in Western Costa Rica, and thence as far as 

 Santa Fe in the State of Panama. It is perhaps more numerous in the neighbourhood 

 of Chiriqui than elsewhere. On the line of the Panama railway, E. cristata takes its 

 place.
