the length of the tail ; in the latter the hind limb measures a little 

 less. 



Upper surface generally minutely granulate, wdth numerous 

 linear grooves and more or less distinct and more or less numerous 

 warts furnished with a dark granular, conical or spine-shaped 

 horny tubercle. These warts are mostly developed along the sides 

 of the body and head, along the limbs and on the tail ; they are 

 also very frequent on the upper part of the head and on the back, 

 rather seldom and scarce on the abdomen and on the lower surface 

 of the limbs. In specimens from Lake Gaube, which I consider 

 to belong to var. rucjosa, the skin is roughly tuberculous, especially 

 on the base of the tail ; the warts are here decidedly conical with 

 spiny tubercles. Very seldom, and, as it seems, only in females 

 during the breeding-season, the skin appears nearly smooth. No 

 distinct carpal or tarsal tubercles. 



Coloration. (Plate V. figs. 1, 2, .3, 5.) 



The upper parts are greyish, brownish grey, or olive-grey, uniform 

 or with yellow or yellowish spots. The shade varies in the course 

 of the year and in different individuals at the same period : how- 

 ever, the colours get merely darker or lighter, and the predominant 

 one seems to be as a rule grey, varying from the lightest ash-grey 

 to blackish gi'ey. The yellow-spotted individuals are less abundant 

 than the uniform ones, and the bright lemon-yellow spots are 

 seldom seen in adults ; the yellow is generally very pale or inter- 

 mixed with grey. These spots are very variable in size, shape, and 

 disposition ; they are either small, round, indistinct and scattered 

 along the sides of the body, or larger, irregular, and disposed quite 

 asymmetrically on the back ; very often they are more or less 

 confluent and form a broad vertebral band, which appears some- 

 times interrupted in different places. In cases when it is absent, 

 the median dorsal line is mostly marked, being generally of a light 

 brownish tint. The yellow spots on the tail are frequently much 

 more marked than those over the body ; they are round or 

 rhomboidal, and placed along the upper portion of the tail, or 

 confluent with a yellow band or yellow line which extends over 

 the middle of the tail. This line is nearly always present even in 

 the uniformly blackish specimens, though it is rather seldom of a 

 light and bright colour, but brownish yellow. The dark granules 

 which crown the warts and the spine-shaped tubercles are more 

 distinct in lighter individuals, and especially on the sides of the 

 head, bod)% and tail, where they are surrounded by a yellowish circle 

 or even placed on yellowish or whitish warts. These hght w^arts 

 may appear in great number on the sides of the body and on the 

 lower portion of the tail ; the limbs also possess some. Towards 

 the lower part of the sides of the body, as well as on the sides of 

 the belly, the greyish ground is generally powdered with yellow 

 and spotted with small round or angular and irregularly shaped 

 dark spots : these spots seem never to be absent along the border
