Southern China, Burma, Malay Peninsula, Sipora (Mentawei Islands), Java, Borneo, Celebes. 6. RANA LATICEPS Blgr. Rana laticeps, Blgr. Cat. Batr. Sal. p. 20, pl. i. fig. 1 : S. Flower, P. Z. S. 1896, p. 897. Dr. Hanitsch (Rep. Eaffles Libr. & Mus. 1898) records obtaining Rana laticeps from Gunong Kledang, Ipoh, Perak, in March 1898, at an elevation of 2000 feet. Distribution. Khassya, Bengal, Malay Peninsula. 7. RANA MACRODON Kuhl. (Plate LIX. figs. 1, 1 a.) Rana macrodon, Blgr. Cat. Batr. Sal. p. 24. In the P. Z. S. 1896, p. 898, I pointed out that there appear to be two forms of this species in the Malay Peninsula ; since then I have seen a large number of these frogs, all of which were referable to one or other of the varieties, but I found large specimens of the Penang variety may approach the Singapore variety in colour (having the upper parts reddish or brownish yellow), and in the distance of the nostrils apart being less than the interorbital space. The stomachs of these big frogs generally contain a good deal of foreign matter, bits of leaves, small twigs, sand, fine granite, gravel, and angular pebbles as much as 10*5 m m . in diameter. Their food consists of snails, crabs (Thelphusidae), caterpillars, beetles, crickets, ants, & c , and twice I have found the remains of scorpions (Hormurus sp. incert.) in their stomachs. Sometimes there are a number of parasitic worms between the kidneys and the back. The fang-like bony prominences in the lower jaw are sometimes very sharp and nearly 5 m m . in length. Localities. Penang Hills, 1900 to 2200 feet (November 1896, March and April 1898); Larut Hills, Perak, 3200 to 3400 feet (April 1898): in both of these localities the Penang variety is numerous about water (mountain streams and pools) and grows to a large size. I also got two very typical specimens of this variety near the foot of Gunong Pulai, Johore (September 1897), from which State this species had not previously been recorded ; and it is interesting to thus find the Penang variety at a low elevation (about 200 feet) and so near the island of Singapore. So far I have not come across the Singapore variety on the mainland or at Penang. Colour (in life). One specimen from Penang was unusually coloured, the upper parts being rich bronze-red and the limbs handsomely marked with yellow and dark brown ; below (as usual) the chin was white and the remainder pale orange. Iris (noted from many specimens) : a narrow ring of bright gold round the |
