 nasals apparently contiguous ; a large internasal extending laterally upon the 

 sides of the head, where it joins the supero-nasal and the first frenal plate ; two 

 fronto-nasals, more or less quadrangular, passing likewise down upon the sides 

 of the head, where they join the first and second frenal ; a frontal much longer 

 than broad, narrow behind ; fronto-parietals pentangular ; one inter-parietal, 

 more narrow posteriorly, and two 2:)arietals, larger than the fronto-parietals ; 

 no occipital ; a small naso-frenal ; two frenals and two freno-orbitars ; seven 

 superior labials; a transparent disk to the inferior eyelid; 30 rows of scales; 

 those upon back distinctly tri-carinate, those upon sides also tri-carinate, but

OPHIOPTHALMID.^. 



We have fourteen specimens of Ablepharus Peronii. The predominating 

 color in most of these specimens is bronze, mingled with green, with two late- 

 ral rays bordered with black, as described by Dumeril and Bibron. In some of 

 the specimens, however, the predominating color is brownish above, with two 

 central rows of black spots. Dumeril and Bibron observe that this species has 

 a very wide range, being found, according to them, in New Holland, Otaheite, 

 Java, the Isle of France, Morea and Peru. 



The entire number of species: of Scinecoidians or Lepidosaurian Lizards is 100 ;
