spotless or with a series of blackish spots, which very 

 seldom unite to form a labial streak. The cross-bands 

 on the legs may be very irregular or absent. The 

 hinder side of the thighs, i. e. that part which is con- 

 cealed by the legs when the animal is at rest, is 

 whitish or pale greenish marbled with dark olive or 

 bronzy, or of the latter colour with or without small 

 light spots ; never is any trace of yellow to be detected 

 on that resfion nor at the axil and o-roin. The lower 

 surfaces are white, with greyish spots or marblings in 

 specimens kept dry. After long sojourn in water these 

 parts are abundantly spotted or largely marbled with 

 black. The abundance and intensity of these spots is 

 irrespective of sex — a remark which, contrary to the 

 statement of many authors, applies also to the typical 

 form. The iris is black, veined with gold, the latter 

 pigment being in far lesser abundance than in the 

 typical form. The vocal sacs are strongly pigmented 

 with black, pale grey when swollen out.
