mites, in their structure (Journ, Geol. Soc. vol. xxii. p. 135). 

 Some of my specimens illustrating these points were exhibited 

 at the Meeting of the British Association in Glasgow in 1855 j 

 but I hope, before the end of the present year, to have the 

 opportunity of demonstrating the facts of the case, by means 

 of actual specimens, in the presence of the Geological Society.

XXXIV. — Note on Anolis auratus, Daudin, 

 By Prof. W. Petees. 



Me. O'Shaughnessy, Senior Assistant in the Natural-History 

 Department of the British Museum, has taken great pains 

 (Ann. & Mag. Nat. Hist. 1869, iii. p. 183) to prove, as he 

 fancies, that I had taken a different species for the true Anolis 

 auratusj Daudin, and that I had described the latter as a new 

 species, under the name of Anolis tropidonotus. I may be 

 allowed a few words to show that his supposition is not tenable, 

 and that he might have avoided this correction by a little more 

 carefulness. 



Daudin (Hist. Nat. Kept. iv. p. 97) says : — " L'anolis dor^ 

 ... est parfaitement semblable . . . aux anolis roquet et 

 raye ; et il ne jparott en differ er^ que par ses doigts entierement 

 amincis, meme a lew extremite et par sa couleur d'un gris dore 

 brillant en dessus, par une ligne longitudinale hlanche, bordee 

 de brunatre, partant de dessous cliaqiie ceil et se prolongeant en 

 ligne droite sur chaque jianc jusqti) aux cuissesJ'' 



Dumeril et Bibron (Erpetologie Gen. iv. tableau, pp. 46 

 et 81) place the genus Norops [Anolis auratus) together Avith 

 other genera " a doigts non-elargis^'' in opposition to Anolis 

 " a doigts elargisj'' and explain this more accurately by say- 

 ing, " ce genre semble former le passage entrc les trois prec(5- 

 dents et celui de Anolis, auquel il tient par quelques-unes des 

 esp^ces chez lesquelles la dilatation des doigts est pen sensible." 

 Respecting the colours, they express themselves (/. c. p. 84) 

 in the following manner : — "iy'w« off're une raie hlanchdtre, qui 

 s'etend depuis Voreille jusqxCen arriere de Vepaule!'^ " Dans 

 notre second individu . . . a la racine de celle-ci {la queue) 

 aboutit une raie hlanchdtre, qui vient du hord inferieiir de 

 Vorhite, en suivant le cote du dos^ In describing the limbs, 

 they say (p. 38), " Port^s en avant, les memhres atteignent, . . . 

 ceux de derriere le hord de Voreille]^'' and the excellent figure 

 (pi. 37. fig. 2) shows distinctly a larger occipital plate.
