COXCLr.SIONS. 



The cullectiuns made by Messrs. Uoherty aud Everett iu Dali, Lombok, ISambawa, 

 Satouda, aud Sumba, registered iu the foregoiug' pages, throw much uew light ou 

 the geographical distribution of the birds iu the Eastern Archipelago. Without 

 presuming that they settle auy ([iiestions iiually, I believe we can draw the following 

 conclusions fnjm the material uow known : — 



1. Although zoologists have lately, in several instances, deuied the great 

 imjjortauce of " Wallace's line," aud although Doherty's and Everett's collectious 

 show that many more Javanese forms have crossed the Lombok )Straits over to 

 Lombok, and many more Timorese forms have crossed the Straits over to Bali, than 

 we formerly knew, the differences between the oruis of Bali aud Lombok are 

 remarkably cousjjicuous, and indeed much more so than those between the oruis of 

 Lombok aud Sambawa, or Samba wa, Flores, and >Sumba. 



2. The fauna of the higher peaks is very poor, which seems in point to the fact 

 that those islands arc geologically youuger than the larger islands with their rich 

 mountaiu fauna. 



3. The forms from the higlier regions are aiijiareutly more Jlalayan iluui 

 Australian. This seems to indicate that the ludo-Malayan are uot the later immi- 

 grants, as in that case they would have driven the original Australian fauna back 

 towards the hills. Pmbably the Indian forms inhabited these islands before the 

 Australian ones, or immigrated at about the same time. 



4. Bali's avifauna is )iot entirehj the same as that of .Ja\a, although very few 

 forms are diifereutiated. 



.J. Sumba's fauna is clnscly allied to that of Samliawa aud Flores, but contains 

 a fair number of jjeculiar forms. 



I hoi)e to l)e able to come back lo these interesting questious more fully ou a 

 future occasion.
