|Title||Remarks on Chalcites malayanus (Raffles)|
|Abstract||Till now it was assumed that the Malay Peninsula, Sumatra, Java, Borneo, and Celebes are inhabited by the typical race of Chalcites malayanus. At Prof. Stresemann's request I compared the beautiful series collected by Heinrich in Celebes with the material in the Leiden Museum and it proved that the above mentioned region is inhabited by more than one race.|
Especially in series these races are well recognizable. Material was kindly sent me on loan by the British Museum, the Buitenzorg Museum, and the Raffles Museum.
Chalcites malayanus malayanus (Raffles) Cuculus malayanus Raffles, Trans. Linn. Soc, vol. 13, 1821, p. 286 (Malay Peninsula).
The upperparts are greenish tinged, in some specimens with a more or less bronze gloss. The forehead with a varying amount of white. The underparts are barred, the breast with several thin bars, the abdomen with heavier and broader bands especially on the flanks. At the moment I consider the Sumatra birds as belonging to the typical race too. The upperand underparts correspond with those of Malayan birds, though in 2 of the 3 Sumatra birds the white on the forehead extends slightly further back than in the birds from the Malay Peninsula.
Seven specimens from the Malay Peninsula Wing 93—98, tail 60—65, culmen 13—15 mm.
Three specimens from Sumatra. Wing 91 + x — 97, tail 61—64, culmen 13 mm.
Chalcites malayanus albifrons nov. subspec.
Upperparts as in Malayan and Sumatra specimens, but the forehead
