    possess, while others want, the white rictal spot, an unstable character among the continental races, but never found, so far as at present recorded, in true B. macrocerca, nor in B. cathceca. Adult Tonghoo birds agree best in the relative proportions of the rectriccs with B. cathceca.'] 441. B. INTERMEDIA. D. intermedins, nobis, J. A. S.

[Tonghoo, Karen nee, Karen hills (TV. B.)\ Moulmein (Beavan). Lieut. W. Ramsay has sent from the localities cited a very numerous series of a species of Buchanga, w7hich provisionally, until I have been able to examine typical Penang examples, are here referred to B. intermedia (Blyth). They vary but slightly in their dimensions when full grown. Wing, 5*25; outer pair of rectrices, 6-12; middle pair, 4*25. Nor is there much if any variation in their colouring when in perfect plumage. Lores, jet black; under surface, pure uniform bluish-ash, with little or no gloss; above, glossy bluish-ash, somewThat darker than below, and paler on the rump; rectrices, ashy-blue. They are almost identical in colouration with Javan B. leucophcea, that bird however being smaller, and having a less forked tail. Wing of B. leucophcea, 5; outer pair of rectrices, 5*38; middle pair, 4. Among a large number of Javan birds I can find no variation of colouration when in perfect plumage. B. mouhoti, Walden, is not separable from this Burman form.] [442. B. PYRRHOPS. Bicrurus pyrrhops, Ilodgs., Gray’s Zool. Misc. p. 84, no. 553. Rangoon, {TV. B.). The Rangoon examples sent by Lieutenant W. Ramsay are all referable to B. pyrrhops. They are identical with individuals from Deyra Doon, Nipaul, and Dacca. In colouration they do not differ from B. intermedia, but their dimensions are considerably larger. Wing, 5*75; outer pair of rectrices, G-50; middle pair, 4’50. In perfect plumage they do not vary among one another. Nor can either they or B. intermedia be confounded with fully-plumaged examples of B. longicaudata, either from Malabar, Ceylon, Simla, Mussoorie, Nipaul, Darjeeling, and Asulu. The ashy Drongos have no representative in Southern India or in Ceylon. AY bile B. longicau¬ data has no representative in Java, so far as is yet recorded, nor have I ever seen a Malaccan or Burman example of it. Along the lower ranges of the
