Birds of Celebes; Alcedinidae. 
and Sharpe (Cat. B. 1892 XVII, 97). Mr. Wallace speaks of the base of the 
bill as red. A comparison of them with P. dichrorhyncha is desirable, as Sula 
birds generally have much more in common with those of Peling than with 
those of Celebes. 
This Kingfisher is easily distinguishable from that of the mainland of Ce- 
lebes by its dichromatic bill, but the distribution of the two colours red and 
black thereon is subject to much individual variation; in one or two specimens 
in the Dresden Museum the entire upper mandible is black except at the base, 
in another example more than half of it is red; the under mandible seems to 
be always red for at least the basal half, sometimes the terminal fourth only 
is black. 
The type and co-types, which were obtained by our native hunters in Peling 
and Banggai between May and August, 1895, are in the Dresden and Tring 
Museums.
