902 Ma. STANLEY S. FLOWER ON "HUE [NoV. l4, 



near Alor Star in Kedah, and also near Jenan in the same State 

 caught a particular!}^ handsome little frog which is referred 

 provisionally to M. ornata, but which differs considerably in 

 appearance from Bangkok individuals. 



Habits. This very active, elegant frog is to be found liiding 

 during the da}- under stones, logs, &c. in the crevices of the mud 

 iu dried-up pools and among dead leaves. Once I found two in 

 an aats' nest, situated in the ground under some brickwork. 

 It comes out at dask and seems to remain abroad alF night. At 

 night in December and January these frogs may be heard croaking 

 in Bangkok ; considering their small size they produce an aston- 

 ishing volume of sound, the noise seems to me indescribable on 

 paper. 



Colour (in life). Usual Bangkok specimens. — Above reddish 

 olive, with a large dark brown mark on the back beginning between 

 the eyes, then naiTOwiug and then widening as it extends to the 

 hind part of the body ; a broad darker brown line along the side 

 of the head and body ; limbs with irregular dark brown cross-bars; 

 a dark horseshoe mark round the vent. Lower surfaces white, 

 extensively spotted with brown on the tlu'oat and chest. Iris : 

 golden ring round pupil, remainder golden speckled with bronze. 



The Penang specimen \Aas above yellow marked with rich dark 

 brown, and below pale immaculate buff. 



Size. The largest Siamese specimens noted measured — snout to 

 vent, d '22 mm., 2 23 mm. Penang specimen (sex not recorded), 

 snout to vent 24 mm. 



Distribution. Kashmir, India, Ceylon, Bui'ma, Southern China, 

 Cambodia, Siam, Malay Peninsula. 



Tadpoles. 



At the end of December 1890 I found tadpoles of this species 

 iu a small pond iu Bangkok ; they were numerous all through 

 January and February 1897, and the young frogs were leaving the 

 water at the beginning of March. On revisiting the same pond 

 the following winter (18U7-98) I failed to see a single specimen. 



Description. Length of body once and three quarters its width, 

 a little more than half the length of the tail. Xostrils placed 

 close together on the upper surface of the head, nearer the end of 

 the snout than the eye. Eyes on the sides of the body, visible 

 from above and from below, their distance apart is about five 

 times the distance between the nostrils, and also much greater 

 than the width of the mouth. On the back between the eyes are 

 a pair of shields, oval in outline, placed side by side ; they are not 

 conspicuous in the living tadpole, but in specimens shrunk in 

 spirit they become so. Spii'aculum median, on lower surface of 

 body, opening into a transparent sheath of skin, in front of the 

 anus. Anus median, opening in the lower edge of the subcaudal 

 crest. Tail about four times as long as deep, ending in a very 

 finely produced point ; upper crest not extending on to the back ;
