ON THE GENUS CITTURA. 139 



C. cyanotis are not yet clearly recognized, and that the female has never been 

 figured. 



" Now as to C. sanghirensis : — 



" This species was first figured by Mr. Sharpe (P. Z. S. 1868, pi. xxvii.). 

 This author says (p. 272) that the figure has been drawn from the type 

 specimen in his collection, and coloured from a very fine example in the 

 Leyden Museum. As the same typical specimen was afterwards figured 

 in Mr. Sharpe's 'Monograph' (pi. 118), these two figures ought to agree; 

 but they appear to me not quite to do so, the first having the sides of the 

 head and the wing-coverts blackish, the latter blue. Can the Leiden specimen 

 be a female ? Mr. Sharpe's typical specimen decidedly is a male ; but no 

 reference has been made to any sexual diff'erences. 



" Neither does Prof. Schlegel, in the year 1874 (Mus. P.-B. Ale. p. 14), 

 consider sexual differences, notwithstanding he enumerates five males and 

 three females. 



"Nor does Count Salvadori, in 187G (Ann. Mus. Civ. Gen. ix. p. 53), 

 enumerating three specimens with blue wing-coverts and two with black 

 ones. 



" Therefore, also, the sexual differences in C. sanghirensis have not yet 

 been noticed, as far as I am aware ; and as at all events an authenticated 

 female specimen has not as yet been figured, we may look upon Mr. Rowley's 

 Plate, which represents such a one, with satisfaction. 



" At all events, the two species are very ' good ' ones, in the same sense 

 that all insular variations are, or even more so. Which of the two may have 

 been the parental form cannot be said in the present state of our knowledge ; 

 but perhaps other allied ones are still to be discovered somewhere on Borneo 

 or the neighbourhood, and will clear up this question. 



" Prof. Schlegel and Count Salvadori knew only the habitat of the Great 

 Sangi for C. sanghirensis. I also got this species from Siao, in the south of 

 Great Sangi, north of Celebes ; and it is perhaps of value to remark that the
