ASIATIC PRIMATE EXPEDITION COLLECTIONS 195 BIRDS FROM MT. KINA BALU, NORTH BORNEO By James L. Peters ACCIPITRIDAE Accipiter virgatus virgatus (Temminck) 2 ad. d\ 1 ad. 9, 3100 feet, 9-26 August, 1937. None of the three specimens has completed the post-nuptial molt and for this reason wing and tail lengths cannot be measured; the tarsal length is 47.5, 45, 48 mm. ICTINAETUS MALAYENSIS MALAYENSIS (Temminck) 1 9 , 3100 feet, 11 August, 1937. Compared with a male of /. m. pemiger from Mt. Angka, Siam, the Bornean bird is much blacker throughout and definitely smaller, wing 550 against 570; if corresponding sexes were to be measured the difference in size would doubtless be even more apparent. PHASIANIDAE Arborophila brunneopectus erythrophrys (Sharpe) 2 ad. d\ 4 ad. 9,2 juv. d% 1 juv. 9 , 5000-5500 feet, 10 June-16 July, 1937. This race was originally described from an adult pair collected on Kina Balu by John Whitehead. When first studying Whitehead's collections, Sharpe thought the specimens represented the young of A. hyperythra described by himself from the Lawas River in 1879, but later became convinced that the characters on which erythrophrys (i.e., rusty lores, superciliary and sides of face as opposed to the ashy gray color of the corresponding parts of hyperythra) was based were not an age character. A. erythrophrys was upheld by Ogilvie-Grant in Cat. Bds. Brit. Mus., 22, 1893, p. 218 but was later synonymized with hyperythra by Sharpe himself in his Hand-list, 1, 1899, p. 29. As far as I can discover this was its fate until reinstated by Chasen, Bull. Raffles Mus., no. 11, 1935, p. 3 in a laconic footnote that reads "A. erythrophrys and A. hyperythra are distinct forms." I have not seen the latter race, but all the Kina Balu specimens agree with the plate of erythrophrys in Ibis, 1890, pi. 4, the rusty parts of the head and face are present in both adults and juvenals. The old females have
