3, 1900; Victoria Point, December 5, 1900). He gives the soft parts as: 

 Iris blackish brown or dark brown; bill bluish white, black at tip and 

 along culmen, becoming horny blue at base; feet dull leaden blue. 



The above series from the Malay Peninsula is considerably darker 

 than the series from the northern and eastern part of Siam; they also 

 average a little smaller. The three specimens from southern Tenas- 

 serim are somewhat lighter than birds from farther south but darker 

 than northern individuals as a rule. In fact, they are intermediate; 

 on the whole, they go better with Peninsular specimens. 



I have examined no specimen from Java, but specimens from Penin- 

 sular Siam and farther south clearly do not belong to the northern form 

 and are placed with the Javan form provisionally until specimens 

 from there can be exammed. A male from Pulo Bauwal, south- 

 western Borneo, does not seem to differ materially from Peninsular 

 birds. Two males and a female from Dutch East Borneo are very 

 dark, darker than anything from the mainland. Though one male 

 was taken February 24 and the other two specimens on November 6, 

 all three specimens are molting, and I think they are birds of the pre- 

 vious breeding season, but the bird of the year of the northern form, 

 harterti, is brownish not blackish. If more ample material demon- 

 strates that these differences hold for the Bornean bird, it would take 

 Bonaparte's name Hemilophus mulleri. 



A male and two females from the Philippines are browner below; 

 the females are from Palawan, but the island is not specified on the 

 male, probably Palawan also. 



With Borneo and Palawan left out of the range as doubtful, the 

 range of Mulleripicus pulverulentus pulrerulentvs would be Java and 

 the Malay Peninsula north to southern Tenasserim, possibly Sumatra. 

 Robinson and Kloss ^^ record it from Pulo Langkawi and Pulo Terutau; 

 Robinson adds Pulo Lontar ®* and Bankok Klap, Bandon.^^ Appar- 

 ently it is not a common bird or else it is wary and difficult to obtain.
