Java and the Philippine island of Negros are the only localities known to be 
inhabited by this Barbet.

52. Macropreryx' comatus (Temm.). 
Cypselus comatus, Temm. Pl. Col. pl. 268, “ Sumatra,” ¢ (1824). 
Hab. Luzon, in January (Meyer). 
The male is distinguished from the female by having the region of the ears deep 
rufous; and all the other male members of the genus display more or less rufous on 
the ear-coverts. 
Luzon examples have the wings nearly half an inch longer than Sumatran and 
Malaccan individuals in my collection. Otherwise no material difference is to be 
observed.

Hab. Luzon (Jagor). 
A species belonging to that section of the genus of which C. francica may be con 
sidered the type. It is the smallest of all the known species of that group, its dimen- 
sions not exceeding those of C. fuciphaga (Thunb.)=C. linehi (Horsf.) A narrow, 
well-defined, pure white band crosses the rump and constitutes its chief differential 
character. 
fifty-sixth plate is referred to by the Messrs. Marshall, although Cuvier’s title based thereon is made a 
synonym of X. rosea. At least it is to be presumed that this is what is meant by Le barbu varbichon (instead 
of barbichon), and by p. 56 instead of pl. 56 (Conf. Marshall, Monogr. Capitonide, pl. 44). 
' T cannot find that the title Dendrochelidon, Boie, was published prior to 1832.
