6 BEPTILES AND AMPHIBIANS FROM MT. MURUD. 



Scales in 19 rows, reducing to 15 before the vent, all strongly 

 keeled except those of the outer row which are only feebly 

 keeled. Ventrals 179, anal divided, subcaudals 63 pairs (tail 

 incomplete). 



Colottr. Dark olive brown above with a chain of small yellow 

 spots down either side of the back in the posterior two-thirds 

 of the body ; neck with reddish and black markings ; upper lip, 

 chin and throat yellow; belly greyish-yellow, with longitudinal 

 chains of small black spots ; tail below dark grey. 



A second female (No. 7209) captured at 7000 feet has the 

 internasals slightly shorter than the praefrontals, a slightly 

 narrower frontal, and on the left side 2 praeocular shields; 

 ventrals 176, caudals 83. The ventral spots are confined to a 

 chain on either side of the belly. 



Natrix mnriidensis is closely related to A^. chrysarga 

 Schlegel from which it differs in the fewer number of maxil- 

 lary teeth and in having only a single anterior temporal shield. 

 N. chrysarga is a common and widely distributed snake rang- 

 ing from the E. Himalayas and S. China to the Malay Archi- 

 pelago, and as far as I am aware two anterior temporals is a 

 constant character. The number of teeth in the maxillary 

 bone in continental specimens varies from 33 to 37, not count- 

 ing the two enlarged posterior teeth. I have not examined 

 the dentition of any from the Malay Archipelago.

3. Gymnodactylus bat^uensis Mocq.

Three specimens were collected at between 4500 and 6000 

 feet. One is an adult male measuring 94 mm. from snout to 

 vent. It has an angular series of 9 praeanal pores and 9 fem- 

 oral pores on either side, with 9 and 10 upper and 8 and 10 

 lower labials. The other two examples are half gTown and 

 in them the femoral scales bear pits onh^ 



The juveniles are coloured light brown above with black 

 spots forming irregular cross-bars. The adult is pale grey 

 in colour and has the markings much paler.
