31 specimens (China 24 , of which nearly all are col- 

 lected by Mr. Swinhoe and Dr. G. Schlegel , Colombo 1, 

 Andamans 2 , Bornjeo 1 , Lu9on 1 , Sanghir 1 , Celebes 1). 



A few remarks may be welcome to ornitologists about 

 the much-disputed specimens from the latter localities. 



The bird from Colombo (Ceylon) is undoubtedly a true 

 and fully adult L. lucionensis. As it is one of Diard's speci- 

 mens, there can be little 'doubt as to the trustworthiness 

 of the mentioned locality. Of the Andaman specimens one 

 is in fully adult, the other in immature plumage. The spe- 

 cimen from Borneo , collected by Schwaner and called En- 

 neoctenus Schwaneri by Bonaparte (Consp. Av. I. p. 363) 

 is a true L. lucionensis. The white superciliary streak is by 

 no means absent , as Bonaparte says in his short diagnosis, 

 but merely hidden by the somewhat overhanging feathers 

 of the crown. The specimen from Lu9on is a true L. luci- 

 onensis with ashy gray forehead and crown , but having the 

 lower surface still banded across like young specimens, 

 thus showing the fully adult stage of plumage on the upper, 

 the immature stage on the lower surface. The same is the 

 case in one of our specimens from Chiua. The specimen from 

 Menado (Celebes), collected by Duyvenbode , is a true L. lucio- 

 nensis in nearly adult stage of plumage , with the forehead 

 and fore-part of crown strongly tinged with ashy gray and the 

 lower surface still, though faintly, crossed with dark zigzag- 

 bars. I have little doubt that the specimen from the same 

 locality in the Dresden Museum (Blasius, J. f. 0. 1883, p. 

 148) will belong to this species and not to tigrinus (mag- 

 nirostris) which latter species is easily recognized by the 

 black-barred back in all stages of plumage. The Sanghir 

 specimen , which was collected by Hoedt , dijffers from the 

 other specimens of lucionensis by the entire forehead and 

 crown being tinged with smoky brown instead of gray,
