bill anil dimensions C. kangeangeiisis is a perfect counterpart of C. sinensis babuttis, 

 while C. celehensifi has a less curved, somewhat more elongate hill, and proportionally 

 a shorter wing and longer tail. 



In its coloration C. kawjeanf/ensis resembles most closely C. <tiidainanen«is ; 

 in fact, it differs from the latter only in a lighten chestnut mantle and jaler 

 greyish head, neck, tail, and underside. The proportions con-espond with those of 

 C andmiianensis, though C. kanf/eanfjensis is altogether much larger. C. cdehensis, 

 on the other hand, is entirely differently coloured, the tail being of the colour of the 

 wings and not like the underparts; the mantle is not in such striking contrast with 

 all the rest of the plumage, the undersurface and neck are brownish, not greyish. 

 Tlie assumption that C. kangeancjensis is of Celebesian origin or affinities is therefore 

 groundless. 



One of our specimens of C. kangeangen^is (No. 229j is aj)parently immature, 

 and differs from those described above, the much-worn tail being barred and scribbled 

 with wavy whitish cross-bars. The other sjiecimens vary also to some extent. The 

 tail-feat her.s, when quite freshly moulted, are smoke-grey, but seem to fade into a 

 buffy-grey colour, though the colour is apjarently sometimes paler already when the 

 feathers are fresh. The upper tail-coverts are either uniform or barred. The latter 

 state is probably due to more or less young age. The colour of the neck and uiidei- 

 surface varies as described above, and I cannot confidently, from the si)ecimens in 

 hand, say that the darker colour is that of the fresh plumage. Last, not least, there 

 is a curious fact obvious : there are in two of our specimens, apparently adult birds, 

 a few single black feathers on the head, neck, and underside ; while, in another, two 

 or three feathers of these parts have blackish tijjs and edges. 



Centropus kangeangensis is the most interesting species of the birds inhabiting 

 the Kangean Islands. 



The local name is also "dudut." 



54. Gecinus vittatus (Vieill.)

Java).

Kangean E., W., S.E., N. Four males, three females. " Iris roth, Fiisse 

 graugiiin (griinlichgrau), Schnabel schwarz, unten gellilich." (Nos. 26, .iS, 84, 102, 

 123, 135, 1S7.) 



We have no specimens of G. vittatus from Java or Sumatra, but only Bali 

 specimens, which seem to agree perfectly with Ja\a specimens as well as with our 

 series from Kangean. 



Native name : " slati."

Unfortunately only one female (No. 38) of this rare bird was obtained in the 

 north-we.st of the island. "Iris roth, Fiisse schwarzgrau, Schnabel oben dunkclbraun, 

 unten gelbgrun." This siiecimen agrees with females from Java and Bali, but the 

 bill is somewhat small. It would be interesting to compare a series. 



Local name : " slati."
