Iguana sepiformis. Laur. Amph. p. 47. 



A MIDDLE-SIZED, or rather small species : na- 

 tive of North America : first described by Lin- 

 naeus in the Museum Adolphi Friderici. Body 

 covered with scales carinated and pointed at the 

 tips, and down the back runs a carina formed by 

 similar scales, somewhat more strongly marked : 

 head of an obtuse and somewhat rounded form, and 

 marked on the hind part by a large, callous, bare 

 spot : beneath the throat a strong plait or furrow : 

 body clouded with deeper and lighter shades, and 

 the tail of considerable length. This seems a 

 species very little known.
