9, Philautus mjobergt, sp. nov. PI. fig. 3. 



Type, author's number 7265, collected at 7000 feet in 

 November, 1922. 



Description of the type. Choanae small, oval, partly hidden 

 b}^ the edge of the jaw. Head large, much broader than long, 

 broader than the wddth of the body, snout rounded ; eye pro- 

 minent, nearly as long as the snout ; canthus rostralis sharply 

 defined; loreal region oblique, concave; nostril very near the 

 tip of the snout ; interorbital rejjion 1| times as broad as the 

 upper eyelid; tympanum indistinct, half the width of the eye, 

 its distance from it equal to its own diameter. 



Fingers long, free, but with a fine dermal fringe extending 

 along their lateral edges to the disc ; first much shorter than 

 second which is two-thirds the length of the third ; discs large, 

 as broad as long, that of the third larger than the tympanum. 

 Toes one-third webbed, their discs scarcely smaller than those 

 of the fingers; subarticular tubercles moderate, an oval inner 

 metatarsal tubercle one-third the length of the inner toe, no 

 outer tubercle ; the tibio-tarsal articulation reaches to v^ell 

 beyond ..the snout. 



Skin of the upper parts quite smooth, of the throat finely, 

 of the belly coarsely, granular ; no fringe along the outer edge 

 of the arm or leg. 



Colour. Dark reddish-brown above and on the sides with 

 blacldsh markings, including a ) (-shaped mark in the middle 

 of the back. Throat brown, belly dark brown with large white 

 irregularly shaped spots. Two or three large white oval spots 

 in tlie groin; limbs indistinctly barred. 



Ph. mjohergi is related to Ph. vermiculatus, from the Malay 

 Peninsula, from which it differs in the longer leg and shorter 

 web to the toes and, very distinct, in colouration. 



Variation. Over 50 specimens were collected, all from the 

 higher parts of the mountain ; they show the following varia- 

 tions. The tympanum may be only one-third the diameter 

 of the eye, the interorbital region no broader than the upper 

 eyelid. The tibio-tarsal articulation usually reaches to well 

 beyond the tip of the snout, but may extend only to the tip.
