658. Cyornis banyumas caerulifrons

(658) Cyornis banyumas caerulifrons.

The Southern Blue Flycatcher.

Cyornis magnirostris caerulifrons Stuart Baker, Bull. B. 0.0., xxxix, p. 8 (1918) (Klong-bong-lai, South Siam).

Vernacular names. None recorded.

Description.— Adult male. Very like C. rubeculoides, but has only the front and sides of the chin black, instead of the whole chin and upper throat deep blue; the upper parts are also a duller and darker blue with a more indigo shade in it.

Colours of soft parts. Iris brown ; bill black; legs and feet grey to neutral tint. The bill is pale at the base of the lower mandible in winter.

Measurements. Wing 68 to 73 mm.; tail 54 mm.; tarsus 20 mm.; culmen 12 mm.

Female. Lores and ring round eye pale fulvous; whole upper plumage fulvous olive-brown, rufescent on the upper tall-coverts ; wing-quills and rectrices brown edged with rufous : chin, throat, breast and flanks orange-chestnut; abdomen and under tail-coverts white suffused with rufous. It cannot be distinguished from many female specimens of C. rubeculoides but ha3 possibly a stronger fulvous tinge.

Distribution. North Malay Peninsula and Peninsular Burma and Siam.

Nidification. Not recorded.

Habits. Apparently the same as those of Cyornis magnirostris, from which this bird hardly differs except, in size and its small bill—both forms, however, occurring together over a considerable area.
