The whole series agree well in dimensions with the
specimen from Choungthanoung (between Mergui and Pakchan)
Tenasserim, (wing, yg in = 204 mm.) to which Hume
\Stray Feathers, iii. p. 318 note. 1875) gave the name Caprimulgtis
innominata. As he has pointed out specimen? from
the Malay Peninsula and Tennasserim are certainly intermediate
in size between specimens of C. iudicus indicus
(Lath.) and C. iudicus jotaka (Temm. & Schleg.) in their
breeding areas, and it would be interesting to ascertain if 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 An damans. This
race however has the rump band very inconspicuous, often
indeed hardly discernible, and may be the form that Oberholser
has referred to Collocalia fucifaga rcstita (Less.) tProc.

Both this and C. innominata, 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 considerable
rentals.
