is no constant sexual distinction but the series as a whole 
differs in being much more heavily squamulated below than 
in the Sumatran birds and in having the forehead, sides of the 
head and lores decidedly less rufous. From the Himalayan 
Pnoepyga pusilla it differs in this heavier squamulation and in 
having the forehead and lores not concolorous with the 
occiput. The differences which are not very evident when 
only single specimens are examined are sufficient, in view of 
the large series available to warrant separation and the Malay 
Peninsula bird may therefore be characterised as 
PNOEPYGA PUSILLA subsp. HARTERTI nov. 
Intermediate between P. pusilla pusilla (Hodgs.) from the 
Himalayas and P. pusilla lepida, Salvad., from Sumatra. 
Differs from the former in the fact that the sexes are not 
conspicuously different, in having a dull rufous forehead and 
in the much heavier squamulation of the undersurface. 
From the latter differs in the duller lores and sides of the 
head, which are not nearly so rufous and in the generally 
whiter undersurface. 
Size apparently slightly smaller than the Sumatran form, 
wing 47-51 mm., bill from gape, 17-18 mm. 
Type. Adult male. Gunong Ijau, Larut Range, Perak, 
4,700 feet, collected on 16th August, 1909 by C. Boden Kloss. 
Specimens examined:—Ten adults and three immature. 
The bird from Siamese Malaya is intermediate between 
this race and P. pusilla pusilla, and is very lightly squamulated 
below. The sides of the head and lores are dull rufous 
(Robinson, Journ. Fed. Malay States Mus. v, p. 107 (1914) ). 
In this section two other species, or rather races, remain 
to be considered, viz :— 
(i.) Pnoepyga pusilla rwfa, Sharpe. 
Pnoepyga rufa, Sharpe, Cat. Birds Brit. Mus. vi, p. 304 
(1884) [Java]. 
We have recently obtained a series of 13 adults from the 
Gedeh, West Java, the typical locality ; the specific name is 
unfortunate as the freshly collected birds are decidedly less 
rufous than either the Malayan or the Sumatran birds. From 
the former it is separable by the whiter undersurface and 
from the latter by the more olive, less rufous upper surface and 
sides of head. The terminal spots to the feathers of the 
upper surface are more discrete and clearly defined than in 
either of the allied races and the blackish edges to the feathers 
less marked. The size is about that of the Sumatran form, 
rather larger than the Malayan.
