The characters assigned to the new form in tlie above diagnosis are supported by 

 the fact that six specimens from Borneo (fom- of whicli were collected by Mr. Hose) 

 now before me agree among themselves in that respect, while they difier etjiially 

 from one specimen from Malacca and another from Sumatra (coll. Klaesi) in my 

 collection.* 



Besides the difference in the shape of the nasal apertures, which might be 

 illustrated by the following diagram : —

I tind that the bill in the Borneo bird is much more slender and weaker, and 

 that the sanguineous colour on the lateral base of the upper mandible is rather n\ore 

 extended, involving as it does the upper margin of the nasal apertures, this being 

 not the case in the other .specie.s. Also the wings are remarkably and the tail is 

 slightly shorter than in the Malacca bird. 



Regarding the coloration of the plumage, there is apparently not the sliglitest 

 difference between the new species and tlie typical one ; nevertheless it appears that 

 in the Borneo bird the castaneous tops of the middle tail-feathers are rather shorter, 

 but as there is much individual variation in this respect, and as the young birds have 

 the middle tail-feathers altogether green, f I don't lay much stress upon this fact. 



If we can rely on the indication of sexes as marked on the labels of my speci- 

 mens which were collected by Mr. Hose (and I think there is no reason to mistrust 

 the statements of this excellent collector), there seems to exist a curious difference in 

 the coloration of the plumage in the two se.xes of this species. Two birds njarked 

 ? ? by Mr. Hose have a broad chin band of ashy grey extending largely over the cheeks 



* The distinctness of the species is also obviously corroborated by a series of skins from Malacca, 

 Sumatra, Xfltuna, and Borneo in the Tring Museum. — K. Hartert.
