Rhinolophus osgoodi sp. nov.

Rhinolophus lepidus subsp. Osgood , Field Mus. Nat. Hist., Zool. Ser., 18,

p. 214, 1932.

Type from Nguluko (27 ° 5' N. Lat., 100° 15' E. Long.), north of Likiang, Yunnan, China. No. 33296 Field Museum of Natural History. Adult male. Collected February 27, 1929, by H. Stevens.

Characters.— Externally very like. lepidus but sella parallelsided, connecting process more rounded and lancet less hastate. General color above light brown, base of hairs light gray; below light gray. Fifth metacarpal usually a trifle longer than fourth; third shortest.

Skull small for a bat with so long a forearm. Shape as in lepidus but smaller with especially shorter toothrows. Mastoid width greater than zygomatic width. Upper premolar two in row; lower premolar three external or half in row.

Measurements.— Type (paratypes in parentheses): Forearm 43.3 (41.5-45.8). Skull: greatest length 16.2 (16.2-16.4); condylo-basal length 14.4 (14.2-14.5); palatal length 2.4 (2.4-2.6); width of nasal swellings 4.3 (4.2-4.3); interorbital width 2.1 (2.1-2.2); zygomatic width 7.7 (7.6-7.7); mastoid width 8 (8-8.2); width of braincase 6.7 (6.7—6.9); upper toothrow 5.8 (5.7—5.8); across canines 3.8 (3.5-3.8); maxillary width 5.8 (5.6-5.8).

External measurements of seven alcoholic specimens: Forearm 42.9-45.8; third finger, metacarpal 32.8-33.9, first phalanx 11.7­ 13.6, second phalanx 14.7-16.3; fourth finger, metacarpal 33.2-34.5, first phalanx 8.8-9.9, second phalanx 10.5-12.5; fifth finger, metacarpal 33.9-34.8, first phalanx 10.5-11.8, second phalanx 10.3-12.2. Ear 12-20; tail 17.5-20.8; tibia 16.6-18.2.

Specimens examined.— Total 10. Nguluko, Yunnan, China, 7 males (4 ale.), 3 females (ale.).

Remarks.— As Dr. Osgood has already pointed out (l. c.), this species combines characters found in both the lepidus and refulgens sections. The greater mastoid width is a character of lepidus while the parallel-sided sella is found in refulgens and feae . The skull is smaller than in any of these. The species is named in honor of Dr. Osgood, who first noticed these differences but who did not have the material needed at the time to work out the characters fully.
