Dicrurus minor Layard, A. M .N. H., (2) xiii, p. 129 (1854) (Ceylon). Dicrurus ater. Blanf. & Oates, i, p. 312 (part.).
Vernacular names. Kari-kuravi (Tarn, in Ceylon).
Description. A much smaller bird than either of the preceding races with a smaller weaker bill but with an equally long tail. Wing 125 to 143 mm , average 133 mm.; tail 135 to 165 mm., average 153.3 mm. : bill about 20 mm.
Distribution. Ceylon only. If a sufficient number of breeding-birds only could be examined, it is probable that the South Travancore birds would be found to be of this race and, on the other hand, a few individuals which have occurred there of exceptionally large size and with heavy bills would possibly prove to be non-breeding visitors.
Nidification. Similar to that of the other races of this species,, but at present not much is known as to its breeding-habits and as to how high it is found at this season. The eggs are like those of the Common King-Crow, though I have as yet seen no pure white ones either from Ceylon or South Travancore. They are, of course, very small. Twenty-one eggs average 24.2 x 18.1 mm.: maxima 27.0 x 19 0 mm. and 26.1 x 19.2 mm.; minima 22.8 x 18.9 and 24-4 x 17.2 mm. The breeding-season is March to the end of April, and only two or three eggs are laid.
Habits those of the species.
