grey or ash-colour, the abdomen being buff. Fine crests add to the 
general appearance. C. macrurus is remarkable for a tuft of blue 
feathers on each side of the nape; C. lewcocephalus has a white 
head; C. /eucotis white ear-coverts ; C. nigricollis a black forehead 
and throat; C. capensis two stripes of black on the back enclosing 
one of white; while that species and C. castwnonotus have maroon 
rumps. The bare skin surrounding the eye is scarlet in C. erythro- 
melon, C. macrurus, and C. capensis, and apparently bluish-grey 
elsewhere. The legs are red in life, fading to buff after death. C. 
striatus is very nearly uniform brown, C. erythromelon shews a 
greenish tinge and has some buff on the head. The sexes are similar, 
nor are the young very different. The length is from eleven to 
fourteen inches. Kafirs consider these birds very good eating. 
Fam. XIV. Trogonidae.—The Trogons are the sole tenants of 
the Sub-Order TROGONES, a very distinct group of birds of brilliant 
coloration—the Quezal, as will be seen below, being the most 
splendid of all. Their general aspect is somewhat heavy ; the neck 
is abbreviated ; the bill, stoutest in Pharomacrus and most slender 
in Huptilotis, is short and strong, with a wide bristly gape, and 
a curved culmen terminating in a hook. The maxilla in these 
genera, as well as in Harpactes and Hapalarpactes, has a terminal 
notch, while both mandibles are more or less serrated in adults 
of Trogon, Hapaloderma, T'metotrogon, and Prionotelus. The foot 
is comparatively small and weak, with the short metatarsus 
feathered and somewhat scaly; the second toe is reversed, a 
“heterodactylous” arrangement (p. 10) unique among birds. The 
moderate wing has ten primaries, and from eight to ten second- 
aries; the upper wing-coverts being elongated in Pharomacrus, 
especially in the males. The long rectrices are twelve in number, 
and are concave at the end with divergent tips in Prionotelus ; the 
feathers, moreover, are often square at the extremity—a noticeable 
peculiarity in the Family ; while in the Quezal, Pharomacrus mo- 
cinno, the male has enormously developed upper coverts to the tail, 
which extend far beyond it, the two median being the longest ; in 
its congeners and in females generally they equal the rectrices ; in 
Luptilotis they are only half the length. The furcula is U-shaped ; 
the tongue flat ; the syrinx tracheo-bronchial ; the aftershaft long ; 
the nostrils are bristly; the adults have no down; and the nest- 
lings are said to be naked for a short period. The large soft
