24 BANGS — COSTA RICAN BIRDS Ee 
the feathers much worn, and some of the wing feathers are dis- 
colored and show signs of wear. Its measurements are: wing, 151; 
tail, 150; tarsus, 25; exposed culmen, 29 mm. 
Trogon underwoodi sp. nov. 
Type, from Volcan Miravalles, Costa Rica, ~ adult, no. 16,581, coll. of 
E. A. and O. Bangs, collected Oct. 28, 1895, by C. F. Underwood. 
Characters.— Adult male’ similar in color to the same sex of T. puella, 
except in having the abdomen, sides and under tail coverts flame-scarlet, 
(those of T. puella being scarlet-vermilion). Similar also to T. aurantei- 
ventris except that the latter has the abdomen, sides and under tail coverts 
cadmium-orange. 
Remarks.— Although the color of the under parts of T. wnder- 
wood? is intermediate in shade between that of 7. puella and T. 
auranteiventris, 1 do not consider the bird to represent an inter- 
mediate form, because in regions where 7. puella and T. awrantei- 
ventris occur together they do not intergrade. 
In 1896 Salvin mentioned the peculiarities of the Miravalles 
trogon, but considered it an intermediate, and one specimen (also 
thought to be an intermediate), that is apparently similar to those 
from Miravalles, is recorded in the ‘Catalogue of the Birds of the 
British Museum,’ Vol. XVII, p. 455, from Barranca, Costa Rica. 
Very probably this example came from the mountains above Boca 
Barranca (all the trogons of this sort — T. puella, T. aurantewentris 
and T. underwoodi — are strictly mountain birds), for these moun- 
tains are not far from, and in the same general watershed as, 
Miravalles. 
I therefore consider the new bird a distinct species, and I think 
it probably will prove to have an extensive distribution im the 
broken mountain ranges of northwestern Costa Rica, a region 
where, so far as I know, neither of the allied forms — T. puella 
and T. auranteiventris — has ever been found to occur. 
I have named this species for Mr. C. F. Underwood, in par- 
tial recognition of what he has done in the field of Costa Rican 
ornithology. 
17 have seen but one, immature, female of the new form. ‘This skin does not 
differ much from young females of 7. auranteiventris.
