of _Hypsipetes psaroides_ which are exactly similar to this last described egg, that in, perhaps, indifferent light he mistook this bird for a _Dicrurus_. I may add that the first described type, of which I have procured numerous specimens from different parts of the Himalayas, taking _several_ nests with my own hands, is most characteristic of this species. In the type with the pinky-white ground, large or small spots often occur about the large end of a deep purple colour, so deep as to be almost black, and but for the absence of gloss some of these paler eggs are very close to those of some of the Orioles. Intermediate varieties between the two types above described occur, but in not one of more than sixty specimens that I have examined has there been any perceptible gloss. The eggs vary in length from 0·85 to 1·01 inch, and in breadth from 0·7 to 0·75 inch, but the average of fifty-one eggs is 0·95 by 0·74 inch. 329. Dicrurus nigrescens, Oates. _The Tenasserim Ashy Drongo_. Dicrurus nigrescens, _Oates; Oates, B.I._ i, p. 315. Mr. Oates found the nest of this Drongo in Pegu. He says:--"I found one nest on the 27th April at Kyeikpadein, near the town of Pegu, on a small sapling near the summit. It contained four eggs[A]; they are without gloss; the ground-colour in all is white. In three eggs the whole shell is marked with spots of pale purple; these are perhaps more numerous at the thick end, but not conspicuously so. The fourth egg is blotched, not spotted, with the same colour. [Footnote A: I recorded the nest and eggs of this bird under the name of _Buchanga intermedia_ (S.F. v, p. 149). The parent birds of these eggs are fortunately still in the British Museum, and I am able to identify them with this species, which occurs generally throughout Tenasserim and many parts of Lower Pegu.--ED.] "The nest is composed of fine twigs and the dry branches of weeds; it is lined very firmly and neatly with grass. Exterior diameter 5 inches and depth 2; egg-chamber 3½ inches across and 1¼ deep. The outside of the nest is profusely covered with lichens and cobwebs. The eggs measure from ·83 to ·95 in length, and ·68 to ·71 in width." 330. Dicrurus caerulescens (Linn.). _The White-bellied Drongo_. Dicrurus caerulescens (_L._), _Jerd B. Ind_ i, p. 432.
