Hab. Indian Continent, Malay Peninsula and Borneo. 



Five specimens from British India and five from Borneo. 



This species is distinguished from its congeners by the 

 conspicuous fulvous shaft-streaks to the feathers of the 

 forehead, which is, as a rule, more fulvous than crown 

 and back. The Indian specimens have the hinder part of 

 the lower surface ochraceous buff, deepening into rich 

 tawny buff on vent and under tail-coverts. Sharpe (1. c), 

 who could compare a rather large series, says that the 

 Malayan and Bornean specimens are less ricbly buff under- 

 neath than those of British India , but that the differences 

 are too slight to found a specific difference upon. Our 

 Museum does not possess any specimen from the Malay 

 Peninsula, and our Bornean specimens showing the dif- 

 ferences mentioned by Sharpe in a very strong degree, 

 it is not without some reserve that I declare them to be- 

 long to this species. The pale shaft-streaks on the fore- 

 head are less fulvous and the birds are also very much 

 less fulvous on the lower surface than the true M. Ahhotti. 

 Amongst our Bornean birds of this species are found a 

 larger and a smaller form. One of the larger two, a female 

 from the Kahajan River, is the type of 3iyiothera concreta 

 Mull. MS., the other, likewise a female, has been collected 

 by Schwaner, also in Southern Borneo. The two some- 

 what smaller specimens, also females, from the Karau 

 River (a confluent to the Barito) , bear the MS. -name 

 Myiothera Schwaneri Temm. A specimen of the larger 



specimens being incorporated under the letters p and q to the series of Turdi- 

 nus Ahhotti in the British Museum, I have no doubt as to their real be- 

 longing to this species.
