 Hah. Mountain districts of North Celebes, as well as the Sula Islands [Wallace). 

 The diagnosis by Mr. Wallace was taken from Sula examples. Neither does it, nor 



do Sula individuals [mus. nostr.) altogether agree with the description given by Prince 



Bonaparte (I. c).

Hah. Timor, Flores, Lombock, Bourn, and the whole archipelago from Sumatra to 

 New Guinea, Celebes {Wallace); Sumatra {Baffles); Java {Horsfield); Andamans 

 {Beavan) ; Cape York, Moreton Bay, Queensland, Mysol, Menado, Manilla, Andamans, 

 Java {mus. nostr.). 



I am unable to distinguish individuals of the white-bellied Swallow-shrike inhabiting 

 the Philippines, Andamans, Java, Lombock, Mysol, Australia, and Celebes. In colora- 

 tion they appear to be absolutely identical. In dimension, with the exception of the 

 large Celebean form, they vary but little. I have therefore included all under the 

 oldest title given by Linnaeus to the Philippine bird. The Celebean is much the 

 largest, and ought, perhaps, to receive a separate specific name. Mr. Wallace (P. Z. S. 

 1863, p. 485) entitles the Timor bird A. leucogaster, var. ; but it was from Timor 

 specimens that Valenciennes described A. leucogaster. 



A. mentalis, Jard. (Fidjee Islands), and A. melaleucus (Forsten), a good species (New 

 Caledonia), belong to this group. A. monachus (Temm.) ought, perhaps, to be also 

 included.
