_=Copsychus stricklandi stricklandi=_ Motley and Dillwyn: White-rumped Shama.--_Specimens_, 14. Cocoa Research Station: [Male] testis 8 x 5 mm., August 28, 1962, MCT 2826; [Male] testis 11 x 6 mm., September 5, 1962, MCT 2873; [Female], November 28, 1962, MCT 3359; [Female], November 29, 1962, MCT 3389. 12 mi. N Kalabakan: [Male], October 12, 1962, MCT 3012; [Female], October 12, 1962, MCT 3013; [Female] brood patch, oviduct enlarged, October 17, 1962, MCT 3069; [Female], October 19, 1962, MCT 3078; [Female], October 26, 1962, MCT 3154. 5.5 mi. SW Tenom: [Male], December 23, 1962, MCT 3514. Ulu Balung Cocoa Estate: [Male], July 15, 1963, ADG 200. Oil Palm Research Station: [Female], August 27, 1963, ADG 263; [Female], August 28, 1963, ADG 268; [Female], October 4, 1963, ADG 291. This species was common in the cocoa and surrounding secondary forest at Quoin Hill, but I saw it only once in the moss forest on the mountains near Tenom. No specimen taken showed characters of or tendencies toward _C. malabaricus suavis_. Perhaps the zone of intergradation on the east coast is farther south than Darvel Bay, where it was placed by Smythies (1960:390). S. D. Ripley (_in_ Peters _et al._, 1964:72) considered _C. stricklandi_ to be specifically distinct from _C. malabaricus_, and his opinion is accepted here. _=Enicurus leschenaulti borneensis=_ Sharpe: White-crowned Forktail. _Specimens_, 4: 12 mi. N Kalabakan: [Female] imm., October 21, 1962, MCT 3112; [Female] largest ovum 2 mm., October 27, 1962, MCT 3167; [Male], November 1, 1962, MCT 3195. Gum-Gum: [Female], September 24, 1963, ADG 282. I saw this species only once in life, along a small, wet-weather stream. The specimens, however, were all netted in primary forest, some distance away from any stream. Judging from measurements, these specimens are _E. l. borneensis_, although one would expect to find only _E. l. frontalis_ at elevations of 600 feet. The specimen taken by Garcia at Gum-Gum was not identified to subspecies. _=Enicurus ruficapillus=_ Temminck: Chestnut-naped Forktail.--_Specimens_, 3: 12 mi. N Kalabakan: [Male], October 21, 1962, MCT 3113; [Male], November 4, 1962, MCT 3207; [Male], November 8, 1962, MCT 3231. This bird was common along the upper Apas River at Quoin Hill. All specimens were taken in nets stretched across streams. _=Zoothera interpres interpres=_ (Temminck): Chestnut-headed Ground Thrush.--_Specimens_, 9: 12 mi. N Kalabakan: [Female], October 28, 1962, MCT 3171; [Female], October 24, 1962, MCT 3138. Kalabakan: [Female], November 17, 1962, MCT 3300. Cocoa Research Station: [Female] imm., June 10, 1963, ADG 120; [Male], June 12, 1963, ADG 130; [Female] imm., June 15, 1963, ADG 141. Oil Palm Research Station: [Male], August 15, 1963, ADG 233; [Male], August 9, 1963, ADG 217; [Male], August 27, 1963, ADG 261.
