Si/Htematic Notes. — The blue race runner is the oldest known form 

 of Cnemidophorus., having been figured by Seba in 1734 as ''^Lacerta 

 hrasiliensis de Bahia.^^' It Avas given a binomial [Lacerta lemrm- 

 eata) by Linnaeus, who adequate!}' diagnosed it in 1758, and from 

 that time until it was placed in the genus C nemidophorus by Dumeril 

 and Bibron in 1839 it was referred to various genera besides the 

 original Lacerta. Typical specimens became known as caerideus 

 through Laurenti (1768), as cyaneus through Merrem (1820), and as 

 caeimleocephala. through Kuhl (1820) and others. Bocourt (1874) 

 suggested that the Ameiva cyanom^las of Maximilian de Wied-Neu- 

 wied (1824) was perhaps lemniscatus., but this supposition seems to 

 be rather far fetched, since the photograph shows only two distinct 

 light lines on each side, and a single middorsal line. It wotdd ap- 

 pear that cyanonielas was placed in the right genus, and is, perhaps, 

 rather near to Ameiva septemlineata or ^1. edracantha. 



There is nothing distinctive in the Ameiva lineata of Gray (1838), 

 and it is evident that the types were lemniscatus. Therefore, Boul- 

 enger (1885) is followed in listing it in the synonymy of the present 

 form. Cnemidophorv,s scut at a^ described by Gray (1845) from an 

 indefinite locality, was imperfectly diagnosed, and Boulenger, with 

 the types available to him, placed it, likewise, in the synonymy of 

 lemniscatus.
