Out of this list seven species, to the names of which an asterisk 

 is prefixed, have, as far as I know, not been before recorded as oc- 

 curring in Sumatra. In addition to the above-named species are 

 three which appear to be new, viz. : — 



DiCRURUS SUMATRANUS, Sp. U. 



This species seems to find its nearest ally in Bierurus bimaensis, 

 Wallace', from Lombock, Sumbawa, and Flores. It, however, 

 differs in having the plumage of the back pure black, without any 

 metallic gloss. It also resembles that species in the form of the 

 feathers springing from the base of the maxilla and covering the 

 nostrils ; but in the present bird these feathers are much lengthened, 

 reaching over nearly two thirds of the length of the bill. The rictal 

 bristles are also much exaggerated, projecting nearly as far as the 

 point of the bill. The Sumatran bird is also larger than Z>. bi- 

 maensis, having a wing of .5"9 inches length against 5*5 in British- 

 Museum examples of the latter species (Wallace gives 5-25, ^. c). 

 The tail is nearly square, one specimen only exhibiting a slight ten- 

 dency in the outer tail-feathers to curl at the tip. 



The collection contains ten specimens of this Drongo, collected at 

 Ayer-angat, Paio, and Mount Sago. 



Iris vermilion {Bock). 



TURDINUS MARMORATUS, Sp. U. 



Reddish chocolate-brown, brightest on the flanks and belly, the 

 feathers of the head and back margined with black, giving those 

 parts a scale-like appearance. Beneath, the chin and throat and 

 upper breast white, each feather with a black terminal bar, which 

 becomes wider towards the breast ; the lower part of the breast and 

 centre of abdomen as far as the crissum black, with a terminal or 

 subterminal bar of white across each feather; ear-coverts dark
