bles that of Xiphocercus, or somewhat less so of Phenaco- 

 saurus, while the scales of the body and the form and struc- 

 ture of the gular appendage — it is never a "pouch" — are strik- 

 ingly unlike any of the Anolinae now known. 



It is important also to remember that the dewlap of Tropi- 

 dodactylus, which Boulenger states is "not inflatable," is really 

 capable of being both contracted and folded so that it is 

 decidedly similar to the dewlap of Anolis, which can also be 

 expanded, but never, of course, "inflated." Tropidodactylus 

 represents an Anoline stock which has become modified for 

 fossorial life as Norops is for a purely cursorial existence. 

 The new genus may be called 



Diaphoranolis gen. nov. 



Tympanum distinct ; body very strongly compressed, 

 entirely covered with juxtaposed pavement-like scales; no 

 dorso-nuchal crest; male with a non-extensible, plicate, pen- 

 dulous gular appendage covered with scales similar to those 

 of the body; digits evenly and rather extensively dilated, with 

 subdigital lamellae, the distal joints slender and raised as in 

 Anolis ; no inguinal pores ; tail long, much compressed ; it curls 

 laterally and probably is slightly prehensile as in some Anoles, 

 notably homolechis ; lateral teeth tricuspid ; abdominal ribs 

 present. 



Diaphoranolis brooksi' sp. nov. 



Type: M. C. Z. 16,297, from Mt. Sapo, eastern Panama, 

 2,500 feet elevation ; Barbour and Brooks, collectors ; April, 

 1922. Head medium, nearly twice as long as broad ; forehead 

 very slightly concave, covered with rather large, irregular
