The whole series agree well in dimensions with the 

 specimen from Choungthanoung (between Mergui and Pak- 

 chan) Tenasserim, (wing, yg in = 204 mm.) to which Hume 

 \Stray Feathers, iii. p. 318 note. 1875) gave the name Capri- 

 mulgtis innominata. As he has pointed out specimen? from 

 the Malay Peninsula and Tennasserim are certainly inter- 

 mediate 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 Ober- 

 holser has referred to Collocalia fucifaga rcstita (Less.) tProc. 

 L. S. Nat. Mils. 42, p. 15 (1912)) allocating to it specimens from 

 Sumatra. East Johore and Simalur. 



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 consider- 

 able rentals.
