The whole series agree well in dimensions with the 
specimen from Choungthanoung (between Mergui and Pak- 
chan) Tenasserim, (wing, 7°9 in = 204 mm.) to which Hume 
(Stray Feathers. 111, p. 318 note, 1875) gave the name Caprt- 
nulgus innominata. As he has pointed out specimens from 
the Malay Peninsula and Tennasserim are certainly inter- 
mediate in size between specimens of C. indicus indicus 
(Lath.) and C. indicus jotaka (Temm. & Schleg.) in their 
breeding areas, and it would be interesting to ascertain 1f these 
intermediate-sized birds have themselves a distinct breeding 
area, in which case. C. indicus innominata, Hume would be a 
fairly well defined subspecies. In default of this information 
I prefer to leave the question open.

These two birds, wing 122 and 121, agree closely with the 
large series obtained by us on the islands of the Bandon Bight 
in 1913, and which were named C. merguiensis, Dr. Hartert’s 
statement that this race was identical with C. germaini, Oustalet, 
having escaped our notice. The race is fairly distinct, being 
marked by having the pale rump band with clearly defined 
shaft stripes but is close to C. f. inexpectata, Hume, which is 
found on the Tioman group of islands and on the coast of 
Johore, but was originally described from the Andamans. This 
race however has the rump band very inconspicuous, often 
indeed hardly discernible, and may be the form that Ober- 
holser has referred to Collocalia fucifaga vestita (Less.) (Proc. 
U.S. Nat. Mus. 42, p. 15 (1912)) allocating to it specimens from 
Sumatra. East Johore and Simalur. 
Both this and C. imnominata, which can scarcely be 
distinguished in life and on the wing, were very abundant in 
all the limestone islands along the coast, the caves in which 
they breed being annually leased out to Chinamen at consider- 
able rentals.
