L. G. ANDERSSON, NEW LIZARDS FROM SOUTH AMERICA. 7 



tail in spirit puiple. When the animal has been taken up 

 from the spirit the whole under surface soon becomes enarael 

 white, except on the throat which retains a faint bluish green 

 colour; these whitish scales are marked behind with a row 

 of very minute black döts, only discernible under the magni- 

 f3^ng glass. The bhie colour of the throat is sharply defined 

 from the black of the sides. On the body this limit is not 

 so well marked as on the neck, the two next rows below the 

 black lateral band being partly black, partly light (white or 

 bluish green).

This new species corresponds rather well with T. hifasci- 

 atus A. Dum. especially in the colour, but it differs widely 

 from the same by quite smooth scales on the body and on 

 the anterjor part of the tail, and by the arrangement of the 

 shields of the head. In T. hijasciatiis the prsefrontals are 

 broadly in contact, the frontonasal is much smaller and an- 

 gular behind, frontal hexagonal and nearly as broad poster- 

 iorly as anteriorly,interparietal longer, narrower, and distinctly 

 tapering behind. There is only a single long and narrow 

 infraorbital below the eye. In addition to this the scales on 

 the body are smaller (29 transverse rows on the back, and 

 19 on the belly). It appears also that the hind limbs are 

 shorter in T. bifasciaius. Boucourt states the length of the 

 hind limbs to be only 20 mm in a specimen which measures 

 52 mm between end of snout and vent (Boucourt: Miss. Se. 

 Mex. Rept., 453), and in a specimen, examined by myself 

 and measuring 53 mm from end of snout to vent, the hind 

 limb is 23,5 mm, and does not rcach the axilla. In the pre-
