BATRACHIANS FROM SOUTHERN ANNAM. 431 



Lygosoma stellatum Blgr. 



Bouleng., Rept. Malay Pen. p. 87 (1912). 



1 ex., Dalat. Before known only from two specimens, the 

 types in the British Museum, from the Larut Hills, Perak. 

 My example differs in that the prefrontals just miss contact, and 

 the black spots on the neck and shoulders are arranged to form a 

 broad vertebral band. 



Lygosoma corpulentum, sp. n. 



Section Riojm. Distance between end of snout and arm twice 

 in distance between axil and groin. Limbs well developed, 

 short, pentadactyl, widely separated when adpressed. Snout 

 obtuse, eyelids scaly, supranasals in contact behind rostral ; 

 frontonasals forming a good suture with frontal ; prefrontals 

 small ; frontal broader than the supraocular, longer than the 

 frontoparietal and interparietal together ; parietals in suture 

 behind the interparietal ; 4 supraoculars ; 2 loreals, posterior 

 longest ; 7 supralabials, 6th subocular ; temporals small and 

 scale-like ; ear-opening small, subcircular, about half the size of 

 the eye-opening, without projecting lobules ; a large azygos post- 

 mental ; 36 smooth scales round the middle of the body ; 

 prseanals slightly enlarged ; digits short, compressed, 4th toe a 

 little longer than the 3rd, 12-13 keeled lamella) inferiorly. 



Head and body, 170; tail, 150 mm. 



Colour in life. Light chocolate-brown above, mingled with 

 yellowish on the flanks; lips, sides of neck, and throat yellow. 

 Belly brownish-white. Labial shields edged black. 



A single specimen obtained at Dalat. Author's No. 2128. 

 Closely allied to L. bamfyldii Bartlett, from Borneo, Sumatra, 

 and the Malay Peninsula, from which it differs in the absence of 

 lobules to the ear-opening, number of scales round the body, 

 colour of the head, and size. 



DlBAMUS MONTANUS, Sp. 11. (Text-fig. 2.) 



Snout covered with 7 more or less complete shields ; a high,
