(659) Cyornis banyumas dialilaema.

Salvadori's Blue Flycatcher.

Cyornis dialilaema Salvador!, Ann. Mus. Civ. Genova, xxvii, p. 387 (1889) (Taho, Karenni).

Vernacular names. None recorded.

Description.— Adult male. Differs from the Southern Blue Flycatcher only in being a duller blue and in having the abdomen and under tail-coverts much more suffused with rufous.

Colours of soft parts and Measurements as in the preceding bird. Wing 71 to 74 and one specimen 79 mm.

Female. Only differs from that of Cyornis rubeculoides in being darker below.

Young. Above rufous-brown, with pale central streaks to the feathers of the back, head and scapulars; the wing-coverts with fulvous spots and the breast bright orange-rufous mottled with brown.

Distribution. Hills of Central Burma, North to Shan States and Yunnan and the Kachin Hills East of the Irrawaddy. It is quite impossible to distinguish between Cyornis whitei (Harington), Cyornis glaucicomans (Oberholser) and Cyornis dialilaema (Salvadori), the last of these names has priority. Gryldenstolpe says it is the most common form of Blue Flycatcher in Northern Siam.

Nidification. Harington and Grant both found this bird breeding in the Bhamo Hills and Shan States. Nests obtained with eggs differed in no way from those of Cyornis tickelliae and C. rubeculoides. Twenty eggs average 18.6 X 14.2: maxima 20.5 x 14.5 and 18.5 x 15.2 mm.; minima 16.9 x l4.0 and 17.4 x 13.5 mm.

Habits. Those of the genus but it seems to be more entirely a forest-bird, summer and winter, than most. The extent to which it is migratory is not at present known.
