178. Trocon virints, Linn.; Lawr. J. ¢. vii. p. 290. 
179. TROGON ATRICOLLIS, Vieill. 
It is probably this species which Mr. Lawrence calls 7. aurantii- 
ventris (J.c. vil. p. 290), and afterwards (viii. p. 3), following Ca- 
banis, 7’. tenellus. We doubt its real distinctness. 
180. TRoGon caieGatus, Gould; Lawr. J. c. vii. p. 290. 
Mr. Lawrence’s description of his 7’. concinnus (1. c. vii. p. 463) is 
evidently taken from a young bird, the rounded tail-feathers and the 
double character of the markings of the wing-coverts being charac- 
teristic of a young male. The differences, then, between 7’. con- 
cinnus and T. caligatus, as pointed out by Mr. Lawrence, are reduced 
to the more general “ bronzy-green”’ colour of the former, as com- 
pared with the “greenish blue”’ of the latter. A specimen in the 
collection agrees well with Mr. Lawrence’s description; but, com- 
paring it with our series of 7’. caligatus, we prefer to attribute the 
slight difference of shade of colour to age of feathers rather than to 
specific distinctness.

183. CHORDEILES VIRGINIANUS, Briss. 
Agrees with North-American specimens. 
184. NycrrpROMUS GUIANENSIS, Gm.; Sclater’s Cat. p. 281. 
N. americanus, Lawr. (nec Linn.) (vide Scl. P. Z. 8. 1861, p. 77) 
1. ec. vii. p. 290. 
N. guianensis, Lawyr. l. ¢. vii. p. 290. 
There seems to be but one species of Nyctidromus inhabiting 
Central America and the northern portion of the southern continent. 
A large series in Salvin’s collection from Guatemala well illustrates 
the variations of plumage and size to which this bird is liable. 
Nyctibius grandis is included in Mr. Lawrence’s list.

185. GLAvucis AFFINIS, Lawr. 
G. hirsutus, Lawr. l. c. vii. p. 319. 
Mr. Gould says this species is from the highlands of New Gra- 
nada; but these examples are from the hot district, not much above 
the sea-level. It is doubtful whether Glaucis ever ranges high up 
in altitude.
