the type of which is only a small specimen of H. sparverioides ; 
nor is it H. strenuus, Gld., said to have come from the Phi¬ 
lippine Islands, which was described from a much distended 
skin of the same species. 
On a closer examination of a good series of H. fugax, it 
is evident that many of the specimens are those of quite 
mature birds. It follows therefore that we have in H. fugax 
a species which in maturity retains a plumage which in most 
other Cuckoos would denote immaturity. The same remarks 
apply to the H. nanus, Hume, a pretty little Cuckoo from 
Tenasserim—in fact, a miniature of H. fugax (wing 5*5 to 6 
inches). In Cuculus sonnerati, Lath., and C. pravatus, Horsf., 
we find two species which never get beyond what is known 
as the hepatic phase of plumage in Cuckoos. H. fugax and 
H. nanus resemble H. sparverioides and H. bocki in having the 
upper surface brown, but in the striations of the breast they 
are more like the young of H. hyperythrus. 
The Cuckoos of this subgenus may be arranged as shown 
in the table on page 158.

Cyornis banyumas (Horsf.), apud Tweedd. P. Z. S. 1878, 
p. 615, $ (p. 610). 
The female of the two birds sent from Palawan by Mr. A. 
H. Everett was attributed to C. elegans by Mr. Sharpe, Cat. 
B. iv. p. 447. 
Lord Tweeddale was in error, I think, in referring it to 
C. banyumas , inasmuch as this specimen is a brown bird of 
the C. rubeculoides group, whilst C. banyumas belongs to the 
C. tickellice group, in which the female is blue, like the male. 
The bird now sent by Mr. Maitland-Heriot is a female, 
which most resembles C. elegans, but differs in having the 
throat and breast pale olive-brown instead of bright rufous. 
I propose to name it C. herioti, after the sender.

It is worthy of note that the birds from Negros and Gui- 
maras are much larger (wing 4*35 inches) than those from 
Luzon, Zebu, and N. Mindanao (wing 37 to 4 inches).
