Show 906 MR. STANLEY S. FLOWER ON THE [Nov. 14, November 1897. It is a singularly handsomely marked frog, and well merits its specific name of pulchra. Distribution. Siam, Cambodia, China, Hongkong. 31. MICROHYLA ACHATINA (Boie). Microhyla achatina, Blgr. Cat. Batr. Sal. p. 166. Localities. This pretty little frog was known to inhabit the Malay Peninsula from d and 2 specimens sent to the British Museum from Malacca by Mr. D. F. A. Hervey ; it does not seem to have been previously recorded from Siam. I have obtained specimens on Penang Hill, at from 2000 to 2500 feet elevation, in Nov. 1896 and April 189S ; in Taiping, Perak, in M a y 1898; in Bangkok in July 1898 ; in the Dong Phya Fai, about 900 feet elevation, in Nov. 1897; and I have received specimens from Chantoboon. Habits. A very active frog; at times taking very sudden, long hops like a " grasshopper " insect, at others using its dilated digital disks in climbing like a true tree-frog. Colour (in life). Upper parts vary from very pale light bronze-brown to rich bronze-red, speckled in irregular longitudinal lines, with very small dark brown spots, a very pale yellow vertebral line, and a conspicuous dark brown or black pattern on the back. The sides are rich dark brown or black. Lower parts purplish buff. Iris golden. Size. Snout to vent 20 m m . Distribution. Tenasserim, Siam, Malay Peninsula, Sumatra, Java, Moluccas. 32. MICROHYLA BERDMORII (Blyth). Microhyla berdmorii, Blgr. Cat. Batr. Sal. p. 166. Localities. This species, although known from Burma, Malacca (Davison), and Cambodia, does not seem to have been recorded from Siam. In Nov. 1897 I found it numerous near Hinlap, in the Dong Phya Fai, Siam, elevation about 700 feet. Habits. Nocturnal, frequenting the neighbourhood of water, an extraordinary good jumper (even for a frog). Size. Snout to vent 43 m m . Distribution. Burma, Siam, Cambodia, Malay Peninsula. 33. CALLULA PULCHRA (Gray). Hylcedactylus bivittatus, Cantor, p. 143. Callula pulchra, Blgr. Cat. Batr. Sal. p. 170 (hand & c fig.) ; S. Flower, P. Z. S. 1896, p. 908. " Eung-ahng " of the Siamese. " Bull Frog " of the English in Singapore and Siam. Localities. This species apparently does not occur in Penang; but is now common in Singapore, having been (from all accounts) imported into that island from Siam. The only instances of its occurrence on the mainland of the Peninsula (that I know of) are |
