of Pteruthius and our Heterornis ; Heterornis at all events must take 
place next / teruthius; but I think the true position of Stachyris is 
among the Brachypods, near to Jéra and Icteria, with the forms 
that we shall next give, and leading to the Crateropodans. 
Genus Mivornis, mihi. 
General structure of Jéra, but the bill quite different and Meruline ; 
commissure and culmen subarched throughout; tarse lower and not 
exceeding the large thumb with its nail; tail fully rounded. Type, 
M. ruficeps, mihi.—Timalia gularis of Horsfield ? 
M. ruficeps.—Body vernal green, passing to yellow on the throat 
and breast, where also there are dark lines down the shafts of the 
plumes ; cap, wing and tail brunescent; bill bluish horn; legs fleshy 
grey; iris hazel. Length 53 inches; bill, 2; tail, 24; tarse, 13; 
central toe and nail, =%; hind, ;8;; closed wing, 23. Sexes alike. 
Genus Erpornis. 
General structure of the last, but the bill very straight, compressed, 
with the culmen well-raised and keeled between the nares, as in Sta- 
chyris and in Jéra, but less thick and rounded and the notch more 
remote than in Jéra; wings longer and more acuminate, with the 
first three quills less equally gradated ; legs smaller; tail even. 
Type, Erpornis vanthochlora, mihi.—Above vernal yellow, below 
white ; legs and bill fleshy grey ; iris brown. Five inches long; bill, 4; 
tail, 2,; closed wing, 23; tarse, 14; central toe and nail, =%; 
hind, ,8;. Sexes alike. 
Remarks.—The above two forms are much related to each other, 
as well as to Stachyris and the other Brachypodan clinging-birds ; but 
Mizornis inclines towards Timalia among the Crateropodans, while 
Erpornis is nearer to Stachyris and Zosterops, which last I consider 
to be a Brachypod. Both inhabit the lower and central hills, and 
feed on tiny tree-insects and their larve and pupe. ‘Their tongue 
is simple. 
Genus Jvulus. 
General structure of Polyodon, but the bill, tongue and nares sim- 
ple, and Brachypodan, not Meliphagian ; bill short and singly notched 
at the tip. 
Type, Polyodon flavicollis or Yuhina flavicollis, as printed. 
Remark.—Polyodon is a strictly Meliphagian form. Jzulus is one 
of the genera serving to connect the true Honeysuckers with the re- 
pent Brachypods, such as Zosterops, Chloropsis, &c., and which are 
so like the former. 
CRATEROPODIN#E. 
Genus Pyctoris, naihi. 
Bill short, strong, perfectly entire, arched throughout the culmimal 
and tomial lines; nareal fosse and scale obsolete; rictus with very 
strong short bristles; orbits nude; wings short and feeble, the first 
two quills much, the next two little gradated; third pair equal and 
longest ; tail long, broad and gradated throughout ; legs and feet ty-
