A single fine specimen from Sarayacu. 



This fine and conspicuous species is related to Ecpleopus (Eu- 

 spondylus) maculatus, Tschudi ; and as regards the principal cha- 

 racters of the head-shields, and gular and anal scutellation of that 

 species figured by Prof. Peters, does not exhibit any marked dif- 

 ferences. Tschudi' s figure of the entire Lizard indicates, however, 

 a very different general appearance, more like that of Proctoporus 

 fraseri, O'S., based by me on a specimen formerly confounded 

 with E. maculatus in the British Museum, but differing from it in 

 the absence of fronto-nasals. The present species of Euspondylus 

 presents a remarkable likeness to the Gerrhonoti named Elgaria 

 by some authors. Amongst other points of difference a|iparent 

 from a comparison with the descriptions of Euspondylus maculatus 

 of Tschudi and Peters, it would appear that the very well developed 

 series of infraoculars is not distinct in Tschudi's species as figured 

 by Peters, also that the scales are smaller, and that a longitudinal 

 black stripe on the side of the neck is very characteristic of Euspon- 

 dylus maculatus, while there is no such stripe in the Lizard before us, 

 nor indeed any markings distributed longitudinally. Moreover 

 the black dorsal bars are very different from the quadrangular black 

 spots described by Tschudi, and distinguish it at once from all 

 other Lizards of this group.

This curious species, so different from all its congeners, is well 

 represented in Mr. Buckley's collection, there beiug numerous 

 specimens from Canelos, two from Pallalanga, and one from Sa- 

 rayacu.
