Show 1890.] BATRACHIANS, ETC., FROM SUMATRA. 37 8. MICROHYLA ACHATINA, Boie. M. 9. MICROHYLA INORNATA, sp. n. M. Snout obtuse, shorter than the diameter of the orbit; interorbital space a little broader than the upper eyelid. First finger m u c h shorter than second; toes moderately elongate, quite free ; tips of fingers and toes dilated into very small disks ; subarticular tubercles very distinct ; inner metatarsal tubercle very small, round ; no outer tubercle. The tibio-tarsal articulation reaches the eye. Back covered with small smooth warts. Dark brown above, spotted or marbled with black; sides of head black, with a series of white spots along the upper lip ; lower parts brown ; throat of male black. Male with a subgular vocal sac. From snout to vent 20 millim. Three specimens, two males and one female. 10. PHRYNELLA PULCHRA, Blgr. M. Two male specimens, agreeing with the types from Malacca. The specimen from the mountains of Perak, referred to this species by Giinther (Ann. & Mag. N. H. (5) xx. 1887, p. 313, pi. xvi. fig. B ) , is a distinct species, which I will call P. pollicaris on account of the strong tubercle-like rudiment of pollex which is developed iu the male of this species but not of P. pulchra. Other differences are found in the stouter habit, the shorter head, the presence of a strong transverse fold connecting the posterior borders of the eyelid, the shorter and thicker digits with much stronger subarticular tubercles, and the hardly half-webbed toes. The coloration is also a much plainer one. 11. BUFO MELANOSTICTUS, Schn. M., I. 12. BUFO QUADRIPORCATUS, Blgr. M. 13. BUFO PARVUS, Blgr. M., I. 14. BUFO ASPER, Gravenh. M., I. ] 5. LEPTOBRACHIUM HASSELTII, Tsch. I. A larval specimen with well-developed limbs, obtained by Mr. Iversen, enables me to name several tadpoles of rather large size, from Larut, Perak, presented to the Museum in 1886 by Dr. J. Anderson. These are remarkable in being marked all over with numerous deep black dots. Spiraculum sinistral, equally distant from the end of the snout and from the tail; latter once and a half as long as the body. Length of body 25 millim. 16. M E G A L O P H R Y S NASUTA, Schleg. M. |
