VISCOUNT WALDEN ON THE BIEDS OF CELEBES. 



The islands to the eastward of Celebes (the Papuan or Austro-Malayan region of 

 Mr. Wallace) are characterized by a large number of peculiar genera. Of these at least 

 forty-four are absent from Celebes. Besides the families of the Epimachidse and the 

 Paridiseidae, important groups, such as Podargus, Pachycephala, and Manucodia, are all 

 wanting. Nor does a single Papuan Muscicapine form occur in Celebes. Papuan 

 genera belonging to the two great orders Psittaci and Columbse, orders which are so 

 largely developed in the Australian region, and in no part of that region to a greater 

 extent than in its Papuan subregion, are found in Celebes. This fact is justly regarded 

 as sufficient to stamp the ornis of that island with a Papuan character. Yet among the 

 Psittacidse such essentially typical Australian genera (also Papuan) as Lorius and Plar 

 tycercus do not extend to Celebes. And several peculiar Papuan types are there 

 unknown. The Columbse of the Papuan subregion are well represented in Celebes; 

 yet, with one exception (Phlogoenas), all the Papuan genera of the Gouridge are 

 missing 1 . 



By the annexed table it will also be seen that several remarkable Papuan forms 

 belonging to another characteristic Papuan family (Alcedinidse) are not found in 

 Celebes. 



1 Calcenas is a migratory form.
