LÖNNBERG & ANDERSSON, A NEW LIZARD AND A NEW FROG 3 



tlie first. The series of scales between the supraciliaries and 

 the supraoculars appear to be larger and better developed 

 t han in T. rufescens and T. teguixin. Two loreals are present 

 but the anterior is much smaller and not in contact with the 

 labials (fig. 1). About 9 upper labials, separated from the 

 orbit by a series of infraorbitals. The temporal region is 

 covered by rather large scales except on a narrow strip be- 

 tween the eye and t lie uppermost part of the tympa- 

 nnm, below the enlar- 

 ged siipratemporal sca- 

 les (which form a conti- 

 nuation of tlie supraci- 

 liaries) and the series of 

 scales just below them 

 which also are some- 

 what enlarged. The 

 mental shield is broad 

 and truncate posteri - 

 orly. The lower labials 

 are eight in number; 

 the first is partly in 

 contact with the first 

 chinshield, but its pos- 

 terior part and all the 

 others are completely 

 separated from the chin- 

 shield s by a series of 

 shields which from the 

 sixth lower labial are 

 larger than the lower 

 labial series (figs. 1, 3). 



The chinshields are large (except the sixth = last), the first 

 is single, and the next pair forms a median suture as in 

 T. teguixin but unlike T. rufescens (according to the 

 quoted figure). The gular scales are convex, roundish or 

 oval in outline anteriorly, larger and flatter in front of the 

 fold and on the same, but smaller and granular between 

 the folds. The body is covered above with strongly convex 

 scales which are larger than those in a T. teguixin of about the 

 same size as the new specimen, and at the same time more 

 strongly rounded, while in T. teguixin the quadrangular shape
