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 fairi\ large material in this museum bear.-, 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. in. salvadorii, 

 Sharpe (Proc. Zool. Soc. London, 1875. p. 99, pi. 22. tig. 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. igj) but the former is hardly adult as shown by the 

 huffy 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 (203-211 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.
