Under the name P. notosiicta, Mr. Hewitt and I provisionally 

 identified seven examples of this genus, indicating at the same time 

 tiiat our specimens were by no means typical [l. c). I have since 

 compared ours with the examples of this genus in the British 

 Museum and find that our specimens represent a new form. Its 

 distinguishing characters are as follows : — Head flat and de- 

 pressed; loreal region very oblique; nocanthus rostralis; a rounded 

 or moi'e or less pointed snout projecting only slightly l)eyond the 

 mouth ; discs of digits larger than in any other known species of 

 the genus ; on each side in the sacral region a small prominent 

 tubercle. In the naturnl arrangement of the genus, P. inguinalis 

 appears to be intermediate between the new species and 

 1\ notosticta. 



Descrijition. — Head | as long as broad, flat and depressed ; 

 snout rounded or more or less pointed, extending onl}^ slightly 

 beyond the mouth ; loreal region very oblique ; no canthus 

 rostralis ; interorbital region twice the breadth of the upper 

 eyelid ; tympanum distinct, | or nearly equal to the diameter of 

 eye. Tongue typical for the genus. Vomero-palatine teeth in a 

 long chevron-shaped transverse series, interrupted in the middle, 

 and extending just beyond the choante. Fingers moderate, dilated 

 into large triangxrlar discs, that on the third finger being | the 

 diameter of the eye ; fiist finger considerably shorter than 

 second, with only slightly expanded disc ; hand with flat inner 

 and outer metacarpal tubercles coalescing medianly. Toes rather 

 .short, expanded into ti-iangular discs, that on the fourth toe being 

 about I the diameter of the eye, that on the fifth toe small. Toes 

 free *. A flat elongated inner metatai'sal tubercle, rather poorly 

 developed. 



* In 1913 {I. c.) we stated that the toes li;ul trace of webbing at the hasc. Wo 

 ^vl•ongly interprfited the integument which is usually present in a more or less 

 developed torui at the base of webless toes in many frog-s as a rudimentary webbing.
