Show 168 MR. G. A. BOULENGER ON REPTILES [Feb. 21, two strong glands behind the angle of the mouth. Greyish above, uniform or with small blackish spots ; a black stripe below the canthus rostralis, over the tympanum, and along the outer edge of the dorso-lateral fold ; upper lip white ; flanks and hinder side of thighs pale, with black spots; limbs with regular dark crossbars ; lower parts white, uniform or with some greyish spots on the throat and breast. Male with small internal vocal sacs, without humeral glands, with a strong pad on the inner side of the first finger. From snout to vent, 6 37 millim., $ 45. Three specimens. Nearly allied to R. guentheri Blgr., but distinguished by the broader dorso-lateral folds, the shorter hind limbs, and the much smaller size. 5. RANA ANDERSONI Blgr. A large female specimen, measuring 87 millim. from snout to vent, agrees well AATith a similarly large example obtained by Signor Fea in the Kakhyen hills, Upper Burma. The types are from the Hotha A7alley, Yunnan (5000 feet). Rana schmackeri Boettger (Kat. Batr. Senck. Ges. 1892, p. 11), from Ichang, appears to agree in every respect Avith R. andersonii except in the larger tympanum, measuring three fourths the size of the eye, whereas in the latter species its diameter does not exceed three fifths that of the eye. 6. RANA RICKETTI, sp. n. (Plate XIX. fig. 2.) Vomerine teeth in two small groups close together behind the level of the choane. Head much depressed, as long as broad ; snout shorter than the diameter of the orbit, rounded, projecting beyond the mouth ; canthus rostralis distinct; loreal region nearly vertical, concave; nostril equidistant from the end of the snout and from the eye ; interorbital space nearly as broad as the upper eyelid ; tympanum distinct, small, one third or two fifths the diameter of the eye. Fingers short, depressed, terminating in large disks, which are quite as large as the tympanum; first finger much shorter than the second, third as long as the distance betAveen the anterior border of the eye and the tympanum. Toes rather short, very broadly webbed to the disks, Avhich are a little smaller than those of the fingers ; subarticular tubercles rather small; a small, oval, inner metatarsal tubercle ; no outer metatarsal tubercle. The tibio-tarsal articulation reaches the tip of the snout; tibia a little more than half the length of head and body. Skin finely shagreened above, Avith scattered small flat warts ; a fold above the tympanum ; no dorso-lateral fold ; belly granular. Olive above, marbled with darker; a dark streak on each side of the head, passing through the eye ; limbs with regular dark cross bands ; whitish beneath. From snout to vent 37 millim. Two specimens. |
