190 Barboui — Some New Amphibia Salierdia. 



like asperities on the two inner figures ; there are, as in R. liebigii, asper- 

 ities on the inner side of the arms and unlike that frog, these are plenti- 

 fully sprinkled over the entire chest and throat region to the very edges 

 of the lips. 



Type, No. 2440 of the Amphibian collection in the Museum of Compara- 

 tive Zoology. Taken in the Riu Kin Islands, May, 1904, by a Japanese 

 collector of Mr. Alan Owston. 



Cornufer corrugatus rubristriatus subsp. nov. 



Description. — These two examples, one of which has been figured in the 

 life colors (for a general account of my collection), seem to differ rather 

 widely from typical ('. corrugatus. 



They both lack the characteristic dermal fold which extends from the 

 eye to the shoulder. The tympana are round instead of vertically oval, 

 there are three palmar tubercles, and the tibiotarsal articulation only 

 reaches the eye. The inner sides of the thighs are yellow, and down the 

 brownish olive back runs a brick red vertebral stripe. 



In other characters there does not occur any such divergence. It seems 

 best to consider this a localized island race, and not a distinct species; 

 though more specimens of various ages and from a number of localities 

 might completely separate this race or possibly invalidate it altogether. 



Types, No. 2441, Museum of Comparative Zoology. Two specimens from 

 boon Island, ( ieelvink Bay, Dutch New Guinea. T. Barbour, collector. 



Ixalus pallidipes sp. nov. 



Description. — Snout rounded, as long as diameter of orbit ; canthus 

 rostralis moderately distinct; loreal region slightly concave; nostril 

 slightly nearer tip of snout than eye; interorbital space broader than 

 upper eyelid; tympanum very small, round, rather indistinct, one-fifth 

 diameter of eye. Fingers free, toes not quite half webbed ; disks promi- 

 nent, larger than tympanum ; subarticular tubercles small, a small elon- 

 gate 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, varying 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 sum- 

 mit of the volcano Pangerango, .lava. 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 

 Irakis. The fact, however, that two species of Pohjpalutcs have been 



discovered, viz. /'. edentulus (F. Mull), and /'. anodon (Van Kara pen), 

 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 1'olypedates so that the adult size alone stands as 

 the generic distinction. A very slim one surely.
