>* 1^^ Vol. 69, pp. 207-214 December 31, 1956 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON NEW RACES OF BIRDS FROM LAEM THONG, THE GOLDEN CHERSONESE By H. G. Deignan* In the course of a general revision of the birds of Thailand in connection with preparation of a regional check-list, the several forms described below have seemed to deserve sub-specific recognition. For the loan of comparative material of one or more species and information on specimens not person-ally examined, I wish to express my thanks to the authorities of the British Museum (Nat. Hist.), London, the Museum of Comparative Zoology, Cambridge, Mass., the American Mu-seum of Natural History, New York, the Chicago Natural His-tory Museum, and the Academy of Natural Sciences of Phila-delphia. FAMILY PSITTACIDAE Loriculus vemailis phileticus, subsp. nov. Type. — U. S. Nat. Mus. No. 153682, adult female, collected at Ban Phra Muang [lat. 7°20' N., long. 99°30' E.], Trang Province, Thailand, on 15 March 1896, by William L. Abbott. Diagnosis. — Nearest L. v. vernalis of the Indo-Chinese countries north of the Isthmus of Kra, from which it differs ia adult plumage by having the green coloration everywhere decidedly darker and duller (less yellow-green, more grass green). Range. — The Mergui Archipelago (Sullivan's Island), the southern part of the Mergui District of Tenasserim, and Thailand south of the Isthmus of Kra. FAMILY CAPITONIDAE Megalaima incognita elbeli, subsp. nov. Type.—U. S. Nat. Mus. No. 452629, adult female, collected at Ban Muang Khai [lat. 17°30' N., long. 101°20' E.], Loei Province, Thailand, on 7 January 1955, by Eobert E. Elbel (collector's number EE 4399). Diagnosis. — Nearest M. i. euroa of southeastern Thailand (Chantha-buri and Trat Provinces), from which it is separable by having the throat a blue-suffused green or green-suffused blue rather than cerulean blue; the postocular black streak but narrowly and indistinctly bordered above with greenish blue, rather than broadly bordered with rich blue; 1 Published with permission of the Secretary of the Smithsonian Institution. 36 — Proc.
