Specimens of these two last birds from Bogota are included in Mr. 
Cassin’s catalogue of the Strigide contained in the Museum of the 
Philadelphian Academy.

The Paris types of this elegant bird, whence Vieillot and Lesson’s 
names were derived, are said to be from Trinidad. Lafresnaye’s 
and others I have seen were from Bogota. 
Momotin. 
22. Momorvus BRASILIENSIS, Lath. ? 
The ‘ Momotus brasiliensis ex Bogota’ is one of those local varie- 
ties (climatischen Abirte, as Dr. Cabanis calls them) which are so 
puzzling to ornithologists. In general size and dimensions this bird 
agrees with Cayenne and Para examples, but the bill is decidedly 
smaller. The under plumage is nearly the same. In the Bogota 
bird the black is confined to a smaller space in the middle of the 
vertex, the thalassine blue front extending further backwards, and 
the occipital blue patch being also rather broader. There is also no 
such strongly marked chestnut colour on the nape, but a castaneous 
tinge extends over the upper back. I have not yet examined quite 
adult Bogota specimens, at least none that I have seen have the spa- 
tulation of the medial rectrices complete. Such may perhaps offer 
more decided differences.
