18/8.] MK. D. G. ELLIOT ON THE GENUS PTILOPUS. 553 



Prof. Schlegel (I. c), and names afterwards given to them by M. 

 Salvadori. The principal difference between examples from Celebes 

 and Java appears to be that the former have a much narrower throat- 

 mark, which is lemon-yellow washed with orange.

Hah. Sula, Ceram {Bernstein). 



This form has the throat-mark as in specimens from Celebes. 

 The black band on the occiput is smaller, and the abdomen orange- 

 yellow. The characters it offers to support its claim to a distinct 

 rank are not very striking ; and it may be questioned if it should be 

 really separated from Pt. melanocephalus.

This well-marked race of Pt. melanocephalus differs, both in size 

 and colour of plumage, so much that, more than auy of the other 

 styles, it deserves a separate name. The colour of the throat is 

 of a deeper yellow ; and both abdomen and crissum are orange ; and 

 this colour runs up nearly to the breast instead of being confined to 

 the short under tail-coverts and crissum. It is much larger than 

 any of the other races. 



Male. Head and neck pearly white. Occiput and back of neck 

 jet-black. Throat orange-yellow. Abdomen and crissum bright 

 orange ; long feathers of the under tail-coverts rich carmine. Entire 

 rest of plumage bright yellowish green. Primaries and secondaries 

 margined on their outer webs, near the tips, with lemon-yellow. 

 First primary gradually narrowed towards tip. Bill black, tipped 

 with yellow. Feet very dark red. 



Total length 10 inches, wing 5^, tail 3f, culmen f. 



Female. Entirely green. Feathers of the abdomen tipped with 

 yellow. Some feathers of the under tail-coverts tipped with yellow, 

 others with carmine. Bill black. Feet dark red.
