A Swift, which I refer to this form, was found breeding on 
Tokong Gantang, a group of rocks S. W. of Pulau Tinggi, 
on June 2Ist, 1915, and a single male shot. 
The bird has hardly any trace of feathering on the tarsus, 
is rather dark above, with greenish gloss, the bases of the 
loral feathers are pure white and the pale rump band, with 
dark shafts to the feathers, is clearly defined. The wing 
is 118 mm. 
Four birds, one male and three females, from the adjacent 
island of Pulau Tioman (birds from which island Oberholser 
refers to this species) have the wing immeasurable, as they are 
all in moult, but probably exceeding I10 mm. in all cases; 
one has no trace of pale rump band, in one it Is very clear and 
in the two others very ill-defined. All are darker than a 
series of the closely related C. f. gevmaint, Oust. (C. f. mer- 
guiensts, Hartert) from the islands in the Bandon Bight, 
further North. 
There seems to be no reason why the Tokong Gantang 
bird should not be referred to the near-by C. fucifaga amecha- 
na, Oberholser, from the Anamba islands, described from two 
specimens, while the bird from Pulau Tioman, without 
rump band, would appear to agree with C. fuciphaga vestita, 
as defined by Oberholser, who records a specimen from 
Tanjong Silantai, East Johore, about fifty miles distant. 
Under the circumstances I am in agreement with Ogilvie 
Grant, who thinks that too many races of this group have 
been described on insufficient material and am not there- 
fore prepared to admit that more than one race of this 
Swift exfsts on the coasts of Johore and Pahang to which 
I consider the above name applies.

Oberholser, Proc. U.S. Nat. Mus. 39, 1911, p. 597. 
A single female, shot on June r1gth, 1915, agrees with 
others from the mainland of the Malay Peninsula but has 
the wing rather long, 71.5 mm. 
18. Pycnonotus plumosus chiroplethis, Oberholser. 
Bull. U. S. Nat. Mus. 98, 1917, p. 41 (Anamba Islands). 
Two males shot on 17th and rgth June have the wing g1 
and 86 mm., measured flat. Oberholser’s type series from 
the Anambas which are stated to differ only in size from the 
typical birds from Singapore and the Malay Peninsula have 
the wings recorded as from 83.5 to g0.5 measured across the 
curve (say 86 to 93 measured flat) while a very large series 
from all parts of the Malay Peninsula range from 79=-87 mm.
