OiU' two Peninsular Siani birds differ in no way from southern 

 Malayan specimens of which the wing-lengtlis ranjj-e from 81 to 

 89 mm. Sumatran birds, wings 81-84.5, do not seem to attain -the 

 size nf th«; mainland ones: they have been named H. corcomefopnst 

 by Keichenbach (1854). Bornean birds, of which we have only a 

 pair, wings 79-81, also seem smaller: but, like Sumatran examples, 

 do not. dirter otherwise. They should be placed with the latter 

 apparently; though if comparison of lai'ge series discloses diflerences, 

 the name //. hrooke(i,nns 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).
