detailed description and measurements (of which none are 
given) be relegated to the synonymy. 
Salvadori states, after comparing the type of G. m. 
jacobsont with that of G. modigliani, that the former differs “‘in 
having the upper part and sides of the head somewhat paler 
and the lores more white,” and these again are precisely the 
differences between our Sumatran bird and the four from 
Taiping. The validity of G. modiglianii jacobsom is therefore 
very doubtful. G.m. salvadorii is stated to lack the whitish lores 
and therefore cannot be placed with the Javan and Malayan 
bird. 
Possibly we have only two forms to deal with, a mountain 
race, the true G. modigliani found in Borneo, Sumatra and the 
mountains of the Peninsula and a coastal form met with on 
both coasts of the Malay Peninsula and in Java, which is 
possibly migratory within local limits, as many coastal species 
certainly are.

Evidently rare or accidental at this elevation, as only 
the above specimen was obtained or seen. 
The dimensions, wing 71, tail 74 and tarsus 16 mm. fall 
within the range given by Oberholser, with whose description 
the specimen agrees in other respects.

The Sumatran race of this wide-spread mountain fly-

(Vieill.), of which it is generally regarded as merely a sub- 
species in having the white tips to the tail-feathers more 
extensive,
