AMPHIBIA. 69 



! tain branch of the Buitenzorg Garden at Tjibodas. These specimens agree well 



with van Kampen's notes on one from the same locality. Both vary consid- 

 erably from Boulenger's description, as he has shown. 

 Known from the Natunas, Borneo, and Java. 



Philautus pictus (Peters). ^ 

 Peters, Mon. Berl. akad., 1871, p. 580. Boulenger, Cat. Batr. Sal. Brit, mus., 1882, p. 99. 



Type locality: — Sarawak, Borneo. 



A single example in poor preservation, but evidently belonging to this spe- 

 cies, was taken near the town of Johore Bahru, Malay Peninsula. 



Known now from several stations in the Peninsula as well as Borneo. 



Philautus pallidipes (Barbour). 



"Snout rounded, as long as diameter of orbit; canthus rostrahs moder- 

 ately distinct; loreal region slightly concave; nostril slightly nearer tip of 

 snout than eye; interorbital space broader than upper eyehd; tympanum very 

 small, round, rather indistinct, one-fifth diameter of eye. Fingers free, toes 

 not quite half webbed; disks prominent, larger than tympanum; subarticular 

 tubercles small, a small elongate inner metatarsal tubercle. The hind limb 

 being carried forward along the body, the tibiotarsal articulation reaches beyond 

 the tip of the snout. Skin minutely granular above; beneath both throat and 

 belly more coarsely granular. Upper surfaces uniform brown, varyhig from 

 dark reddish to grayish. Palms of hands and ends of toes yellow. Throat 

 so heavily punctulate with dark brown as to appear almost of solid color, belly 

 and inner sides of limbs less heavily specked on a yellow ground. Outer sides 

 of thighs barred with very deep brown. 



', Type, No. 2442, Museum of Comparative Zoology, from near the summit of 



( the volcano Pangerango, Java. T. Barbour, collector. 



The small size (body 1 inch long for nearly adult female), lack of cranial 



/ ossification, and absence of vomerine teeth place this form with the genus Ixalus. 



The fact, however, that two species of Polypedates have been discovered, viz. 

 P. edentulus (F. Miill) , and P. anodon (Van Kampen) , which also lack vomerine 

 teeth, shows how scant is the basis of separation for the two genera. Cranial 

 ossification is unknown in Ixalus, and, of course, is not general in Polypedates 

 so that the adult size alone stands as the generic distinction. A very slim one 

 surely." Proc. Biol. soc. Wash., 1908, 21, p. 190.
