"Katak pisang" of the Malays according to Mr. L. Wray. Personally 1 think " Kata' pisang " (or Banana Frog) is the proper Malay name for a Rhacophorus, but no doubt any frog with large digital disks would be considered a tree-frog and called by the same name. Localities § Habits. I found this pretty frog fairly numerous on the Bangpakong river, from Tahkamen to Kabin, during March and April 1897, in places where there was long grass on the banks ; also in ditches at Sapatoom, near Bangkok, in Jan. 1898, where its green and yellow colours exactly matched the leaves of the water lettuce (Pistia stratiotes1) among which it was to be found. In Taiping, Perak, in April 1898 it was very numerous in ponds and ditches; two individuals were caught in Penang, April 1898, and I also observed it near Alor Star, Kedah, in June 1898. It is a true water-frog, and appears to occur only at low elevations. Colour. The Bangpakong frogs were more ornamental than Singapore specimens (vide P. Z. S. 1896, p. 203, pl. xiv. fig. 2), although the scheme of coloration was the same. They were as follows iu life :- Above brilliant green ; along each side a line of similar green, separated from the green back by a broad light yellow line (from above the eye to the side of the vent), bordered above and below by broad lines of intense black; below the lateral green line is another line of pale golden yellow (from the angle of the mouth aloug the side, gradually narrowing and disappearing before it reaches the inset of the hind legs), bordered above by a broad line of intense black and below by an irregular line of dark green with iridescent golden shades. A black line on each side of the head from snout to eye ; upper lip very pale golden yellow; tympanum dark rufous brown, with a bright green spot in the centre. Lower parts white, with pale iridescent golden shades. Limbs as in Singapore specimens, above yellowish brown speckled with dark brown, below immaculate buff. Iris : very narrow golden ring round pupil, remainder golden-bronze finely speckled with black. Size. The large Siamese specimen measured, snout to vent 74 m m . Distribution. Burma, Siam, Malay Peninsula, Sumatra, Borneo, Celebes, Philippines. 13. RANA MACRODACTYLA (Giinther). Rana macrodactyla, Blgr. Cat. Batr. Sal. p. 54. Localities.
