描述： Leptolalax oshanensis sp. nov. Tgpe.—No. 1000 Liu Collection, from Mount Omei, Szechwan, 3,500 feet altitude. Adult male, collected June 10, 1945, by ch’ eng-chao Liu. Diagnosis.—This mountain form is closely related to Megophrgs pelodgtoides, from which it can be distinguished by the following characters: oshanensis has no weds between the toes, and the male has paired internal subgular vocal sacs, whereas in pelodgtoides the are one-thied webbed and the male has an in-ternal single subgular vocal sac. The tadpole of oshanensis differs from that of pelodgtoides as the former has no notch between the upper and lower lips and the latter has a deep notch. There are four rows of labial teeth on the upper lip in oshanensis and five and six fows in the Siam specimens of pelodgtoides. Description of tgpe.—Size small, body somewhat depressed and moderately stout (fig.41, A); head as long asbroad,with snout slightly projecting; tongue (fig.41, B) beoad, free behind and deeply micked, no vomerine teeth; choanae large,with two small depressions anterior to and berween the choanae; canthus rostralis well defined; loreal region concave, oblique; nostrils nearer to the tip of the snout than to the anterior corner of the eye; the angle of the mouth only reaching the anterior border of the tympanum, which is very distinct. Arm weak, fingers (fig.41,C) moderately slender, the first slightly shorter than the secind, which is equal length to fourth, the third finger the longest; no nuptial pad developed on any of the fingers; tips of fingers rounded and slightly dilated; on subarticular tubercles, but the third with pad-like elongated elevations; inner metacarpal tubercle very large, and outer one very small. Hind limb weak, the tibio-tarsal articularion reaching the middle of eye, and the tibia adout 43 per cent of the body length; no webs; subarticular tubercles ondistinct, with elongated pad-like elevations; inner metatarsal tubercle welldeveloped; no outer metatarsal tubercle. Skin smooth, with few fine glandular ridges; a few lighet-colored warts dis-tributed around the vent; a distinct well-developed ridge from the posterior corner of the eye extending postero-ventrad from the shoulder region; a light-colored gland on the dorso-basal part of the base of the arm; a rounded white gland with dark edge on the back of the thigh, nearer to tibia than the vent; belly very smooth. Coloration in life.—Reddish brown all over the body, with a black triangular mark on the back of the head, with a few black bars on the mouth, and scattered black spots on the body; black bars are distinctly developed on the limbs and on the fingers and toes. After preservation, the reddish brown becomes grayish brown. Measurements of tgpe (percentage of body length in parentheses).—Body length 27.0mm.; head length 9.5mm.(35.1); head width 9.5mm.
