The difference between the females is alone ample reason 
to divide the eastern birds as a separate subspecies, . but 
beyond this I do not think it is at present advisable to 
create further subspecies on the one unsupported character 
of size. 
Mr. Stuart Baker also described the following new sub- 
species of Jungle Myna :— 
There is little doubt that Aithiepsar grandis of Burma 
and the countries south and east of that country is merely 
a geographical race of the Indian thiopsar fuscus, from 
which it differs merely in size and depth of colouring. 
Swainson’s types of Athiopsar grandis are labelled as 
having come from Sumatra, but this locality is undoubtedly 
incorrect. On comparison I find that they agree exactly 
with the birds found in Central and South Burma and 
Siam, and are indeed identical with them. On the other 
hand, birds from Northern Burma and Manipur are very 
decidedly paler and browner above, and also paler below 
and inclined to fulvous on the centre of the abdomen and 
vent. These birds I name 
ZAtthiopsar fuscus infuscatus, subsp. nov. 
Type. 3. No. 1988.5.80.131. Lower Chindwin, Mears 
Coll. B.M. ; 
Habitat. Burma as far south as Central Arrakan, Lower | 
Chindwin, North Kachin Hills, and Manipur; possibly also 
Cachar. 
As regards size of crest—a feature to which Hume drew 
attention—I can see no general difference between &. f. 
infuscatus and A: f. grandis. The apparent difference is 
due to the way the skins are made; if the crests are allowed 
to lie flat they are inconspicuous and appear small, whereas 
if the skin of the forehead is pulled forward the crest stands 
erect and appears large. 
The two subspecies are much the same in size, infuscatus 
having an average wing-measurement of 133°5 mm. and 
grandis 131°0 mm.
