Show 1897.] REPTILES A N D B A T R A C H I A N S O P CELEBES. 229 entirely webbed, the tips dilated into small disks; a cutaneous fringe along the outer side of the fifth toe ; subarticular tubercles moderate ; inner metatarsal tubercle oval or elliptical, flat, measuring one-third to one-half the length of the inner toe. The tibio-tarsal articulation reaches the tip of the snout or between the eye and the tip of the snout. Skin of the back with small warts or rather indistinct, short, interrupted longitudinal glandular folds; a strong supratemporal fold ; upper eyelids tubercular ; a more or less distinct fold of the skin between the latter. Brown, grey-brown, or blackish olive above, with or without rather indistinct darker spots ; sometimes two lighter stripes on the back and the canthi rostrales, meeting on the tip of the snout; sometimes a light vertebral stripe ; a dark cross-bar between the eyes often present; a black spot sometimes present on the tympanum : upper lip with dark vertical bars, two below the eye; limbs wdth dark cross-bands; hinder side of thighs dark brown, with light spots or whitish marblings ; lower parts white, uniform or speckled or spotted with brown. Male wdth internal vocal sacs. From snout to vent 85 millim. Several specimens : Tomohon, Buol, Matinang Mts. Manado, Gorontalo (Meyer). The specimens referred by Peters to R. macrodon belong to this species. 4. BANA LEYTENSIS, Bttgr. Rana leytensis, Boettger, Zool. Anz. 1893, p. 365. One specimen : Kingdom of Luhu; one specimen : Takalekadjo Mts., towards L. Posso, 3000 feet. Several specimens were obtained in Southern Celebes by Mr. Everett. Originally described from Leyte, Philippines, this species has been rediscovered at Tawi-Tawi, Sooloo Islands, by Mr. Everett, and at Sandakan, North Borneo, by Mr. Douglas Cator. This small Frog (the largest specimen measures only 38 millim. from snout to vent) is closely allied to the preceding, with young specimens of which it may easily be confounded. But the toes are more slender, two-thirds or three-fourths webbed, the three last phalanges of the fourth toe are free from the web and extend beyond the fifth toe, the terminal disk of which corresponds to the second subarticular tubercle of the fourth toe. The first finger extends as far as the second, or slightly beyond. The tibio-tarsal articulation reaches the nostril, the tip of the snout, or a little beyond. The skin of the upper part is warty, some of the warts forming interrupted longitudinal folds, but the dorso-lateral folds of R. palavanensis are absent. The coloration is very variable; some specimens have a bright yellowr or orange spot covering the snout between the canthi and the anterior part of the interocular region : one specimen has a broad yellow vertebral stripe; others have a pair of yellowish dorsal stripes corresponding in position to the dorsal folds of R. palavanensis. Males are provided with a pair of internal vocal sacs. |
