WHITE-BELLIED CUCKOO-SHRIKE. 
Extra-lixnital forms differ in size and coloration, and more than one 
species is confused under the name Graucalus papuensis by recent writers on 
New Guinea birds. 
Berlepsch (Abhandl. Senckenb. Naturfor. Gesellsch., Vol. XXXIV., p. 64, 
1911) recorded the Aru Island bird under the name Graucalus kypoleucus, 
but noted differences and proposed for it, in case the differences proved 
constant, the name Graucalus mertoni.
