ON THE GENUS CITTURA. 141 



1866, duplicates, under the name of Dacelo sanghirensis, some of which came 

 into the British Museum and to Mr. Sharpe. It reminds one nearly perfectly 

 of Dacelo cyanotis, but has the front and a spot at the base of the lower 

 mandible continued to the eye black, all the colours of the plumage much 

 more vivid, and the bird of a somewhat larger size. Wing 3" 9"' to 4" 2'", 

 tail 3" 9'". He adds that the character drawn from the white spots, which 

 ornament the black superciliary stripe, is also to be found in the adult of 

 Dacelo cyanotis. 



"This bird has only been observed on the island of Great Sanghir, in 

 the north of Celebes. 



" Collected by Hoedt and Van Duyvenbode."

" CiTTURA CYANOTIS (Tcmm.). 



"This species occurs in two different dresses, which are rather similarly 

 gaudy. It seems probable to me that also here a change in the coloration 

 takes place, according to the season ; for we meet specimens in the dress 

 No. 1, which are apparently older than others in the dress No. 2, 

 possessing evidently more slender bills. Besides, Sharpe got the commu- 

 nication, through Duyvenbode, that C. cyanotis varies very much according 

 to the season. 



" Dress No. 1 Superciliary stripe rusty yellow. Region of the ear and 

 small wing-coverts dark blue. 



" Dress No. 2. Superciliary stripe clean white. Region of the ear and 

 small wing-coverts deep black. In the dress of transition the white tips of 

 the feathers become smaller, and the blue on the wings appears. 



Younger bird. Bill much shorter and more obtuse, blackish red. Bears 

 perfectly the dress No. 1."
