ON A NEW SPECIES OF TR1BURA (DUMETICOLA.) 221 



and sides of neck, the same, but more dusky ; sides of breast 

 and flanks yellowish, but washed with dusky ; in other respects 

 like the males ; all have the cheeks slightly mottled with pale 

 brown. This is the case with all Reed Warblers and Locustelles. 



The total length of one male was 5*55 ; expanse, 69 ; tail, 

 2'4 ; wing, 2-18; tarsus, "78 ; bill from gape, *65. The tail is 

 much graduated, and the feathers are shaped as in Locwlella. 

 The outer pair fall short of the tips of the central pair by TO, 

 the next pairs successively by "6, *4, '2, and '1. The first 

 primary is *5 long, with the inner web slightly sinuate towards 

 the end ; the third primary appears slightly the longest, the 

 fourth and fifth almost equal to it, but the latter a shade the 

 shortest ; the second *3, and the sixth '1 short of end of wing; 

 the second is equal to the eighth or ninth. 



My friend Mr. Brooks ; to whom I submitted my specimens, 

 assures me that intermedia differs from all the allied species 

 with which he is acquainted, and urges its description as new. 

 He has kindly promised to add a note to this paper stating in 

 what respects the new bird differs from some others of the 

 genus. 



This bird frequents scrub jungle on the banks of the Pegu 

 river, two miles above the Canal Lock. It was the only 

 locality where it was met with, and ten specimens were shot 

 between the 22nd December and 23rd February, after which 

 date no more were procured, though careful search was made 

 for them. They run on the ground, and consort with Locustella 

 lanceolata. 



The habits of both appear to be very similar. Both have a 

 somewhat similar low note, by which alone they can be found. 

 They run on the ground between the tufts of grass and low 

 bushes, and are seen with the greatest difficulty. 



Note by W. E. Brooks. 



The colour of the upper surface is somewhat like that of 

 Acrocephalus dumetorum, but much more inclined to reddish ; 

 but it is not so rufous as in Acrocephalus ugricolus. But for 

 the Locustelle-like, pale-tipped, lower tail-coverts, this bird 

 might almost have been taken for a Reed Warbler of the 

 phragmitis type ; but it has a very much larger first primary 

 than that species. This first, or bastard primary, is, however, 

 much of the same size and shape as that of Acrocephalus 

 bistrigiceps ; the bill is also similar in form to that of bistrigi- 

 ceps, but longer and more compressed at the sides, like 

 Locustella and Dumeticola. The form of the wing is that of 

 Dameticola, but with a slightly smaller first primary. This
