This jay was observed several times at the forest camp at Kalabakan. The bird utters a metallic chattering noise much like that of other jays, except for the metallic quality. I observed it also in moss forest 5.5 miles north of Tenom. Comparison of my specimens with series in the U. S. National Museum and the American Museum of Natural History indicates wide variation within this species in Borneo. The specimens vary considerably in depth of brown, some approaching _P. g. lemprieri_ and others _P. g. coronatus_. Because of this wide variation I have not recognized the subspecies _lemprieri_ and place all specimens from Borneo under _coronatus_. _=Platysmurus leucopterus aterrimus=_ (Temminck): Black Crested Magpie.--_Specimens_, 4: Cocoa Research Station: [Female] brood patch refeathering, 181.6 gm., July 21, 1962, MCT 2628; [Female] imm., 143.4 gm., July 21, 1962, MCT 2629; [Female], September 4, 1962, MCT 2865; [Male], 178.0 gm., September 6, 1962, MCT 2880. The Black Crested Magpie was common at Quoin Hill in secondary forest and cocoa. At the Kalabakan forest camp, I saw a flock of 10 to 20 feeding 70 to 100 feet up in a tree in primary forest. _=Corvus enca compilator=_ Richmond: Slender-billed Crow.--_Specimen_, 1: Pintasan Agricultural Station: [Female], October 17, 1963, ADG 315. Small flocks in the cocoa and secondary forest were common at the Cocoa Research Station. _=Pityriasis gymnocephala=_ (Temminck): Bald-headed Wood Shrike.--_Specimens_, 7: Cocoa Research Station: [Male] one testis, 115.0 gm., October 4, 1962, MCT 2987; [Female] largest ova 15 mm., well-developed brood patch, oviduct enlarged, 140.0 gm., October 4, 1962, MCT 2988; [Male] testis 8 x 5 mm., 121.0 gm., October 4, 1962, MCT 2989. 12 mi. N Kalabakan: [Male], November 8, 1962, MCT 3224; [Female], November 8, 1962, MCT 3225; [Male], November 8, 1962, MCT 3226; [Female], November 8, 1962, MCT 3227. These birds first drew my attention at Quoin Hill by their peculiar whistle, which Smythies (1960:491) calls a "nasal whine." They seem not to descend lower than 30 feet above the ground. They are exceedingly tame; I shot at them two to four times without frightening them off. They were in badly disturbed primary forest at Quoin Hill. At a point 12 miles north of Kalabakan, I found them in primary forest. I took four birds from a flock of five or six. Later in the afternoon, I heard another group in the tops of trees 150 feet high. They seemed to be fairly common, judging by the frequency with which the calls were heard. One of the birds I shot was only wounded and set up such a clamor that soon the rest of the flock approached, seemingly in response to the distress calls. Some individuals came within 20 feet of me. The noise also attracted an accipiter.
