Microhyla imrnata, Blgr. P. Z. S. 1890, p. 37. 



This little frog was described from specimens obtained by 

 Prof. Moesch near Deli, Western Sumatra (P. Z. S. 189U, p. 37); 

 subsequently it was found at Palon, Pegu, by Signor Pea (Blgr. 

 Ann. Mus. Civ. (xenova, 1803, p. 39), and near Bangkok, Siam, 

 by the late Dr. B. Haase (Boetlger, Zool. Anzeiger, 1893, no. 433, 

 p. 430). I have not met this species alive myself, but I received 

 a number of specimens said to have been caught at Chantaboon, 

 Siam. 



Distribution. Burma, Siam, Sumatra.

Microhyla leucostigma, Blgr. Ann. & Mag. Nat. Hist. (7) vol. iii. 

 1899, p. 275, pi. xii. fig. 1. 



I obtained three specimens in the Larut Hills, Perak, at an 

 elevation of 3500 feet in April 1898 ; two of these (the types) are 

 now in the British Museum, and the third in the Baffles Museum 

 at Singapore. A pair were caught in copula : as the mode of 

 embrace does not seem to have been recorded for any Asiatic 

 Engystomatoid Batrachian, it is interesting to note the embrace 

 was axillary, and the fingers of the male did not meet on the 

 breast of the female. 



Colour (in life). Above intense iridescent black, with very small 

 scattered bluish-white spots, which get larger towards the sides 

 and in the anal region. Below very I'ich dark brown (blacl;er on 

 the throat, redder on the belly and thighs), nearly covered with 

 large very distinctly defined spots of intense yellow. Upper 

 surface of limbs reddish brown, w'ith black cross-bars, and thickly 

 studded with very small white spots. Upper surface of hands and 

 feet brown, with bright yellow spots. Lower surface of hands 

 and feet reddish brown. Iris very dark brown, very minutely 

 spotted with pale gold. Pupil circular. The sexes do not appear 

 to differ in coloration. 



Size. 6 . Snout to vent 25 mm. ; arm 14 ; leg 39. 



2 . Snout to vent 27 mm. ; arm 15-5 ; leg 40*5. 



Distribution. Malay Peninsula (Perak). Mr. Boulenger informs 

 me the same frog has been discovered in Borneo, on the Baram 

 river, by Mr. C. Hose.
