These little birds are always rare in collections, more from 
the difficulty in securing them than from any real scarcity. 
The following races, all of which are probably of no more 
than subspecific value, have been described, viz :— 
Gerygone modighanit, Salvad, supra. Toba Lake, N. E. 
Sumatra. 
Gerygone pectoralis, Davison, Ibis, 1892, p. 99. Pahang, 
E. Coast, Malay Peninsula. 
Gevygone griseus, Gyldenstolpe, Ornith. Monatsb. p:; 2 
(1916), id. Kungl. Sv. Vet. Akad. Handl. 56, No. 2, p. 78, P

Gerygone salvador, Buttikofer, Notes Leyden Mus. xv, p. 
174 (1893). Southern Borneo. 
Gerygone modighanti muscicapa, Oberholser, Smiths. Misc. 
Coll. 60, no. 7, p. 11 (1912). Engano Island. 
Gerygone modighaniw jacobsom, Van Oort, Notes Leyden 
Mus. xxx, p. 207 (1909). Western Java. 
In considering the value of these various races the fact 
must not be lost sight of that the species is very probably 
migratory, either partially within a country or over a wide 
range.

The Malay form for instance, so far as we are concerned, 
has only been collected in the Museum Grounds at Taiping, 
in the months of January, June, and August; elsewhere in the 
Malay Peninsula it is known from specimens from Trang, from 
Gunong Tahan between 2,000 and 5,000 feet, Pulau Panjang 
near Junk Zeylon (January), and from the coast of Pahang 
(type), and from Bagan Datoh, S. Perak, September. 
The characters given for G. modiglianiu muscicapa are 
smaller size, “posterior lower parts more extensively and more 
deeply yellow; sides, head, and neck paler, the lores and fore- 
head particularly so, and contrasted more with the surround- 
ing parts.” 
It is doubtful if the United States National Museum 
possesses specimens of the true G. modiglianit from Sumatra, 
but their collection contains examples of G. m. pectoralis from 
Trang, collected by Abbott: Mr. Oberholser has evidently 
regarded these as typical and has compared his Engano speci- 
men with them. The differences, so far as colour goes, are 
exactly those which separate our six Malayan specimens from 
the one recorded above from Sungei Penoh. Gerygone
