454 ON THE SPECIES OE BATEACHOSTOMUS [1877. 



examples the dorsal plumage, the scapulars, the major coverts, and tertiaries are finely 

 striated uith black, with occasional more definite black lines. 



(J (1) adult (■?), ex Malacca. In Malaccan collections examples are as frequently present in 

 which the rufous or rufous-bay colouring is replaced by a dark brown tint, sometimes with a 

 rufous tin^e, the markings being similar to those of the rufous birds. The caudal bands or 

 spots are sometimes of a rufous tint. These brown birds sometimes occur with the dorsal 

 P.Z.S.1S77, plumage finely striated with black and mottled with dark rufous. Wing 5-0, tail 5*25, width of 

 gape 1"31. 



A Bornean (Bedi) example marked d by Mr. Everett (mtis. nostr.) is in the rufous-bay 

 plumage, and is not distinguishable from Malaccan individuals {mt(s. nostr.). If the sex was 

 correctly ascertained, it would appear that both sexes wear similar plumage. Wing 4-90, tail 5-0, 

 width of gape 1*37. 



In B. stellatus the auricular plumes are much less developed than in any of the other 

 species. The front of the tarsus for about a quarter of its length is feathered. The bill is 

 large and massive, and the gradation of the remiges and rectrices is normal.

The Malaccan bird has still to be compared with the typical Sumatran form. I have com- 

 pared the Bornean example with the Malaccan, and can discern no distinction. 

 The species is too well known to require description. 

 The tarsus is well feathered anteriorly in both sexes for more than half its length. 



Batrachostomus, sp. n. 



An example in rufous-brown mottled and striated plumage of an undescribed species 

 of Batrarhostomvs Avas obtained in Mindanao by the ' Challenger ' expedition. It is labelled a 

 female, and will be described in my forthcoming report on the Philippine birds collected by the 

 expedition. The tarsus is feathered anteriorly for a quarter of its length.
