1921] BoDEN Kloss : Notes on Birds. 217 



It seems to ine that a difference between Bornean and 

 Sumatran birds is as yet " not proven " : Dr. Oberholser's 

 material from each place was very limited and it may be 

 noted that he was nnable to distinguish between specimens 

 of Halcyon chloris from those areas.

Mr. Stuart Baker denies the validity of this race, because 

 he behevcs that birds from Johore have wings as long as 

 170 mm. : but he has evidently made a bad geographical 

 error in attributing to the extreme south of tlie Malay 

 Peninsula, the specimens which he thinks come from Johore 

 (Query : Jalor in Patani). 



This subspecies, described on account of itv small size, 

 has now been found to extend to the islands of the Rio 

 Archipelago and to Sumatra. I have examined the follow- 

 ing specimens : — 



c? Si Karang, Johore (cotype). 



d- 



c? Singapore Island (cotype). 



— Kundur Id., Rio Arch. 

 <S Deli Dist. N.E. Sumatra. 



Wings 143-146*-150 mm. Bills from gape 43-45*-48 

 mm. 



PHILENTOMA VEI.ATA CAESIA (Less.). 



The type locality of Dryniophila oelata Temm. (PI. 

 Col., No. 334, 1825), is Java as the species does not occur 

 ill Timor or the Moluccas. 



Birds from Sumatra, Malay Peninsula and Borneo 

 differ from those of Java in having more black on the 

 throats in males ; while the throats of females are blackish 

 blue, distinctly darker than the breasts. 



Birds from each of these areas have received a name as 

 follows : — 



Monarrhu cuesia I>ess., Rev. Zool. 1839, p. 167 (Sumatra). 



Muscicapa pecloralis Hay, Madras Journ. XIII, 1844, p. 101 (Malacca). 



Philcniunia unicolor BIyth, Ibis 186.5, p. 46 (Borneo). 



But all are alike and all must stand as caesia.
