In the paper quoted above Mr. Oberholser has revived 
a name of Peale’s for this common Malayan goatsucker, which 
had escaped Mr. Hartert’s attention and has shown that in 
all probability the specimen came from the vicinity of Malacca 
and not from Singapore as stated. 
The fairly large material in this museum bears out his 
contentions, in that a specimen from Pulau Besar, Malacca, 
agrees with other specimens from further north in the 
Peninsula and differs from three from Singapore Id. including 
an actual topotype of C. m. anamesus, Oberholser (loc. cit. 
p. 593), from Tanjong Katong, in being decidedly larger. 
The latter race is probably valid but larger series from 
Singapore and Sumatra require comparison with series from 
Borneo. Should they prove identical, as may not improbably 
be the case, they will have to bear the name C. m. salvadorit, 
Sharpe (Proc. Zool. Soc. London, 1875, p. 99, pl. 22, fig. 1). 
The large pale form, C. m. albonotatus, does not come down 
south into the Malay Peninsula or even into Southern Siam.

These specimens are rather small (male, wing, 196, 
female, 193) but the former is hardly adult as shown by the 
buffy borders to the white spots on the primaries. According 
to the limits given by Hartert they would fall to C. indicus 
indicus (Lath.), the Indian western form. In view of the 
dimensions of four birds from the adjacent island of Langkawi 
shot in the months December to March (203-21: mm) I do 
not however think this is really the case. 
The species occurs in the south of the Malay Peninsula 
(but apparently only at considerable altitudes) and on islands 
of the Straits of Malacca but only during the months October 
to March.
