This bird was seen only in the moss forest above Tenom. It was not taken in nets the first four days they were erected, nor did we see individuals in the forest. Then, on December 21, three were taken in widely separated nets, and the species was then seen nearly every day for a week. Such sporadic and unpredictable local occurrences may indicate wide separation of the loosely-organized foraging groups of this species. The call is a harsh, jaylike note. _=Criniger phaeocephalus connectens=_ (Chasen and Kloss): Crestless White-throated Bulbul.--_Specimens_, 31: Cocoa Research Station: [Female], December 1, 1962, MCT 3406; [Male] testis 5 x 4 mm., 35.0 gm., July 31, 1962, MCT 2689; [Male], May 2, 1963, ADG 104; [Male], June 22, 1963, ADG 122. 12 mi.
