Systematic notes. — As shown in the preceding historical review, 

 several species of Gnemidojyhotms were known before Wagler's de- 

 scription of the genns in 1830. The species originally placed in 

 the genus were eight in number, including Se^js mvrinus, Tejus 

 cyaneus, Lacerta caeruleoce'phala^ Lac6rta lemniscata^ Tejus ocelU- 

 fei\ Tejus nmelva^ Monitor laterstrigus, and Tejus tritaeniatus. 

 Only four of these forms are now considered valid. Three of them, 

 murinus^ lemniscatus^ and oceUifer^ are here referred to Cneniido- 

 j)honis, but the fourth, now Amelva ameiva a?neiva, is the type 

 species of the genus Ameiva. The original Latin diagnosis of 

 Cnemidophorus may be quoted as follows: " Nares immeditae infra 

 canthi rostralis apicem obliquo-ovales, rostri apici proximae; cauda 

 Ctenodontos; squamae notaei minimae granulosae; gastraei scutella 

 oblongo-quadrata ; antipedes antice serie unica, tibiae subtus serie 

 duplici scutorum. (Dentes maxillares compressi corona bi- aut tri- 

 incisa; plantae pentadactylae.) America." 



It is seen from this that AVacfler did not mention the distinctive 

 lingual characters of Cnemidophorus which offer the only real basis 

 for its separation from Ameiva. The placing of the type species of
