FROM WESTERN SUMATRA. 73 



»Iris carmine, round the eye a narrow ring of blood- 

 red, bill blood-red , feet raisin-red. Native name: Xo/ow^aw." 



With the exception of the size, there is absolutely no 

 difference between Continental and Sumatran specimens , 

 and the inferior size of the latter seems to me not striking 

 enough to base a new species upon. The following are the 

 measurements of the specimens at present at my disposal: 



wing tail tarsi 



Himalayas (2 sp.) 13,7—15 cm. 20,5—22,5 4,3 

 Sumatra (9 sp.) 12,5—13,5 » 15,5—17,5 3,6—3,9 



Mr. Nicholson (I.e.) says that »the female will probably 

 turn out to be much smaller than the male." This however 

 will hardly prove to be the truth , as a female specimen , 

 collected by S. Muller is the largest of the series (wing 

 13,5 cm.) and another female, from Dr. Klaesi's collection , 

 the next in size. Another female of Dr. Klaesi's on the 

 other hand is really the smallest specimen of the series. 

 All specimens received from this gentleman have still con- 

 served their original lively green color of the plumage , and 

 the quills are still red , tinged with golden brown. 



Our Museum contains moreover a specimen which was 

 kept alive in the Zoological Garden at Rotterdam and died 

 in January 1885. The locality from where it was brought 

 is unknown, but its superior size allows no doubt as to 

 its coming from the Continent. It differs however from both 

 the Continental and Sumatran specimens by having the 

 feathers of the crown black , with sea-green tips , which 

 latter are generally interrupted by a subterminal black bar. 

 The feathers on the front and a superciliary streak are 

 pure sea-green , like the whole crown is in the common C. 

 sinensis. Of course I dare not say if this peculiarity is 

 accidentally or constant. For the case however that after- 

 wards the latter might be stated , I propose to call it 

 Cissa nigrocoronata.
