 Some of my specimens illustrating these points Avere exhibited 

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

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

 opportunity of demonstrating the facts of the case, by means 

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

XXXIV. — Note on Anolis auratus, Daudtn. 

 By Prof. W. Peters. 



Mr. O'Shaugiinessy, Senior Assistant in the Xatural-History 

 Department of the British Museum, has taken great pains 

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

 fancies, that 1 had taken a diiierent species for the Xrwo, Anolis 

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

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

 allowed a few words to show that his su})position 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 dord 

 ... est ])arfaitement semblable . . . aux anolis rorpiet et 

 rayd ; et il 7ie j)arott en differer, que par ses doigts enticrcment 

 amincis, meme a hur extremite et par sa coideur d'un gris dord 

 brillant en dessus, prt>' une lifjne hngifudinaJe hkinc/ie, borddc 

 de brunatre, j!?«r?a«i de dessous chaque veil et se irrolongeant en 

 ligne droite sur chaque fane jusqu'' aux cuisses.^^ 



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

 et 81) place the genus Xoroj)s {^Lnoh's auratus) together Avitli 

 other genera "« doiqts non-elargis^'^'' in opposition to Anolis 

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

 ing, " ce genre semble former le passage entre les trois prece- 

 dents et celui de Anolis, aucpiel il tient par quelcpies-uncs des 

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

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

 in the fnllowing manner : — ^^ L^un of re une raie hianchdtre, qui 

 s'dtend deqniis Porcille Jusquen arri^re de rejiaule.'^ " Dans 

 notre second individu . . . h la racine de celie-ci {la queue) 

 ahoutit une raie hlanchdfre, qui rient du hord inferirur de 

 Vorhite, en suirant le cote du dos.^' In describing the limb.*:, 

 they say (p. 38), " Portes en avant, les memhres atteignent, . . . 

 ceux de derri^re le hord de Voreille',''^ and the excellent figure 

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