[tt*«(*oived Jiinunry 10, 1881.] 
(Plates XXIL-XXV.) 
Of the zoological collections made by Mr. Buckley in Ecuador, 
various sections of which have already formed the subjects of pa]>ers 
in these * Proceedings/ uot the lease interesting is the eollectioj) of 
Lizards, both on account of the number of new species it reveals, nnd 
because of the fresh materials it affords for the stu Jy of those already 
known. I have given n partial notice of this collection (P. Z. S. 
1880, p. 491), confined, however, to a preliminary hsfe of the species 
of Anoiis identified, and the description of a beautiful new one. 1 
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 
Iler|ietology of Ecuador as complete as possible. A much earlier 
collection, that of Mr, Fraser, afforded Dr. Gunther the opportunity, 
in 18,^9, of describing and figuring a series of reptiles from the same 
region (P. Z. S. 1859, p. B9) ; and his paper has, of course, been 
frequently referred to. 
1 may point out that the family Oercosaaridae, our knowledge of 
which, so imperfect before Prof. Peters's admirable memoir in 186."^, 
had scarcely been increased siuce that date, has received some 
remarkable accessions in the present collection; also that the genus 
Enyaiius has been further worked out, whilst a new form of the 
curious genus ffophcerm$ has been brought to light.
