This fine and conspicuous species is related to Ecpleopus {Eu-spondylus) maculatus, Tschudi; and as regards the principal characters of the head-shields, and gular and anal scutellation of that species figured by Prof. Peters, does not exhibit any marked differences. 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 apparent 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 Euspondylus 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. 9. ECPLEOPUS (EUSPONDYLUS) STRANGULATUS, Cope. Ecpleopus {Euspondylus) strangulatas, Cope, P. Ac. Phil. 1868, p. 99. This curious species, so different from all its congeners, is well represented in Mr. Buckley's collection, there being numerous specimens from Canelos, two from Pallaianga, and one from Sarayacu.
