Ovtv two P(miiisnlar Siavn birds ditt'er in no way from southern 

 Malayan specimens of Avliieh the wing-h-ngths range from 81 to 

 89 mm. Sumatran })irds, wings 81-84.5, do not seem to attain the 

 size of the mainland ones: they liave been named H. coecomefojDUn 

 by l{(ochenbach (1854). Bornean birds, of whieli we liave only a 

 pair, wings 79-81, also seem .smalh^r : but, like Sumatran examples, 

 do not diti'er otherwise. They should be placed with the latter 

 apparently; though if comparison of large series discloses differences, 

 the name H. hrookeamts Salvad. (1868 : Borneo) is available. No 

 value attaches to the tint of the pale parts (cf. Hesse, Mitth. Zool. 

 Mus. Berlin, vi, 1912, pp. 151-153).
