41-38, averaging 77.5 and 39 mm., the average for the whole 
series of 18 specimens being 79.0 and 4o.1 for the wing and 
tail. 
The difference in colour between our Series and a large 
number from the northern and central parts of the Malay 
Peninsula is, however, very marked, and quite sufficient to 
warrant a subspecific distinction. All the Malayan specimens 
without exception have a conspicuous orange yellow collar 
beneath the scarlet pectoral patch, which is at most only 
slightly indicated in the Sumatran specimens which, in addi- 
tion, have the green centres to the feathers of the abdomen 
and flanks more restricted and the margins of a creamy rather 
than a sulphuty yellow. For this mainland form however, the 
name Bucco imdicus, Latham (Ind. Orn., p. 205 (1790)), is 
already available, while even if distinct from the typical 
Philippine form there is at least one title? in the synonymy 
which applies to the race inhabiting the Indo-Malayan islands, 
exclusive of the Philippines, and until these have been shown 
to be inapplicable one is not justified in accepting Herr 
Parrot’s name.
