VISCOUNT WALDEN ON THE BIRDS OF CELEBES. 67 
ARTAMID. 
ArtAmvs, Vieillot. 
82. ArTamUS MonAcHUS, Temm.; Bp. Conspectus, 1. p. 343, ‘ Celebes” (1850); Wallace, 
P. Z.S. 1862, p. 340; Ibis, 1860, p. 141. (Pl. VI. fig. 1.) 
Hab. 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 (J. ¢.). 
83. ARTAMUS LEUCORHYNCHUS (Linn.): Mantissa Plant. p. 524, ex Brisson, “ Manilla” 
Chir).

Artamus leucogaster (Valenc.) ; Wallace, P. Z. S. 1863, p. 28; Walden, P. Z. 8S. 1866, p. 555; 
Beavan, Ibis, 1867, p. 324. 
leucorhynchus, Wallace, Ibis, 1860, p. 141. 
Hab. Timor, Flores, Lombock, Bouru, and the whole archipelago from Sumatra to 
New Guinea, Celebes (Wallace); Sumatra (Raffles); 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 Linneus 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, Sard. (Fidjee Islands), and A. melaleucus (Forsten), a good species (New 
Caledonia), belong to this group. A. monachus (Temm.) ought, perhaps, to be also 
included,
