THE BIRDS OF NORTHERN THAILAND 285 



below the eye with white shaft streaks; the remiges more conspicu- 

 ously tipped and margined with grayish white ; the entire underparts 

 obsolescently barred with slate gray and grayish white (more defi- 

 nitely posteriorly). Immatures of either sex resemble the adult fe- 

 male but have the general coloration rather paler; the remiges still 

 more broadly margined with white; the entire imderparts whitish, 

 narrowly barred everywhere with blackish. 



This race seems to be resident in suitable territory throughout 

 Thailand proper. I cannot separate my northern material, even on 

 size, from a topotypical series of Kloss's indochinensis, which, itself, 

 appears to be identical with polioptera of Sharpe.

This large caterpillar-shrike is a rather common winter visitor to 

 the hills of the Thanon Thong Chai and Khun Tan ranges (4,000 to 

 5,500 feet) and to the lowland evergreen of Chiang Kai (and perhaps of 

 other provinces). A series of 15 specimens before me was collected 

 between October 24 and February 13, and if Gyldenstolpe's Vol- 

 vocivora luguhris saturata (1916) has been correctly placed with the 

 present race the bird arrives in our districts as early as September 5. 



The migratory form occurs, in season, in exactly the same places 

 as the preceding, from which it seems not to differ at all in habits. 



C. f. melaschista is a larger bird than polioptera: The wings of 15 

 specimens of the former (both sexes) range from 119 to 127 mm. ; of 

 13 northern examples of the latter (both sexes), from 110 to 118 mm. 

 The fully adult male differs from that of polioptera in having the 

 general coloration averaging darker; the remiges and central pair of
