1881. J LIZARDS FROM ECUADOR. 237 



Copeoglossum cinctum, Tschudi, Fauna Peruana, Herpetol. p. 45, 

 pl. 3. fig. 2. 



Mabouia unimarginata, Cope, Proc. Ac. Phil. 1862, p. 187. 



Two from Pallatanga, one from Sarayacu, and two from Canelos. 



Professor Peters fixed the synonymy of Tschudi's Lizard in 18/1, 

 M.B. Ak. Berl. 1871, p. 400. It is easily recognizable from the 

 figure in the ' Fauna Peruana.' Prof. Peters then suggested its pro- 

 bable identity with Mabomja cepedii. Gray. I may as well take this 

 opportunity to remark that there is in fact no difference between 

 the single specimen so named in Gray's Catalogue and M. anea 

 (the name for this common species which apparently has the 

 priority).

 Granulation very fine all over the upper and lateral regions of the 



head and body, and on the gular surface, larger only on the muzzle 

 and on a small anterior space immediately behind the mental plate", 

 where the granules give place to rounded or polygonal scales. La- 

 bial plates large and few in number, four upper and lower, the 

 fourth being very small in each case. Mental shield large ; no post- 

 mental, two of the rounded anterior gular scales a little larger than 

 the others behind it. Scales of the entire lower surface of the body 

 rather large, oval or rounded, begiiming on the throat between the 

 chest and the ear-opening. Tail with broad transverse plates be- 

 neath. Head and fore part of body above and below as far as the 

 shoulder, and including the fore limb, pale brown or yellowish, 

 abruptly terminated by two vertical humeral bands, sometimes 

 meeting above and forming a regular collar of pure white with 

 black borders. The rest of the body, with the hind limb, blue, 

 with black vermiculations elaborately interwoven ; tail darker, with 

 the variegations continued. Inferior surface from chest blue, paler 



again at the hind limb and anal region.
