I wave taken the characters of this species from Messrs. Sclater and Salvin; and I think I cannot do
better than reproduce their remarks on the affinities of the species :—‘‘ We have e-cmmied numerous
specimens of this Trogon from Panama, and have hitherto referred it iS Te: DES. We convinced oe
some time ago, on examining an example from Mr. Lawrence’s collection, that is wes not really 7. niridis,
but were then doubtful whether it might not be 7. venustus, Cab. & Hein. (Mus. Hein. iv. p. 194). On going
into the question again, aided by additional skins of 7° vdis from oe oe We tee convinced that
T. venustus (as characterized 7. s.c.) cannot be considered really distinct from 7° wridis. We have speci-
mens of this bird now before us from Rio, Bahia, Matto Grosso, Eastern Venezuela, and Bogota, and can
find no constant differences amongst them, although there is considerable diversity of tint in the colour of
the lower back, and some specimens approach to what Dr. Finsch has recently proposed to call 7. cyanurus
(P. Z. 8. 1870, p. 559) !

“On the other hand, three Panama skins in the collection of Salvin and Godman present the remarkable
character of the outer tail-feathers above mentioned. The first outer pair are all pure white except :
narrow basal patch concealed by the tail-coverts. Of the See pam considerably more a Cee oe
is white. In the third pair the white apices measure 2 inches a length. We Bass oe ca ue a
T. chionurus. We have seen other examples of this Panama species m Mr. Lawrence’s and Mr. Gould’s

ot i but Mr. Salvin, in a note to me
