[Eeceived January 19, 1881.] 

 (Plates XXII.-XXV.) 



Of the zoological collections made by Mr. Buckley in Ecuador, 

 various sections of which have already formed the subjects of papers 

 in these ' Proceedings,' not the least interesting is the collection of 

 Lizards, both on account of the number of new species it reveals, and 

 because of the fresh materials it affords for the study of those already 

 known. I have given a partial notice of this collection (P. Z. S. 

 1880, p. 491), confined, however, to a preliminary list of the species 

 of Atiolis identified, and the description of a beautiful new one. I 

 now offer the results of a study of the whole collection, and have 

 thought it advisable not to restrict the present paper to the descrip- 

 tion of the new forms, but to enumerate all the species, for the pur- 

 pose of recording additional remarks and revisions which have 

 appeared necessary, and of thus making this contribution to the 

 Herpetology of Ecuador as complete as possible. A much earlier 

 collection, that of Mr. Eraser, afforded Dr. Giinther the opportunity, 

 in 1859, of describing and figuring a series of reptiles from the same 

 region (P. Z. S. 1859, p. 89); and his paper has, of course, been 

 frequently referred to. 



I may point out that the family Cercosauridae, our knowledge of 

 which, so imperfect before Prof. Peters's admirable memoir in 1863, 

 had scarcely been increased since that date, has received some 

 remarkable accessions in the present collection ; also that the genus 

 Eny alius has been further worked out, whilst a new form of the 

 curious genus Hoplocercus has been brought to light.
