Genus ANADIA Gray 



As indicated by Loveridge (1929), it seems inadvisable to attempt 

 anything like a generic revision of these highly variable and little 

 known lizards at this time. From all appearances, it is very likely 

 that future workers will make great changes in the nomenclature of 

 this genus. 



ANADIA BITAENIATA Boulenger 



1903. Anadia bitaeniaia Boulenger, Ann. Mag. Nat. Hist., ser. 7, vol. 12, p, 

 430 (type locality, Escorial and Culata, "Venezuela). 



Two Venezuelan specimens, U.S.N.M. Nos. C6842-43, collected 

 under rocks in damp places at 10,300 feet altitude in the valley 

 of the Chama River in December, 1923, by E. P. de Bellard, may as 

 well be referred to this species as to any other, since many of their 

 characters are those described by Boulenger. Their variation may 

 be outlined as follows: Frontonasal of uneven width, somewhat 

 narrower than long; nasal entire; 4 pairs of postmentals, the an- 

 terior 2 in contact medially (No, 68843), or 3 postmentals on one 

 side of the median suture and 4 on the other, the anterior (2 on one 

 side and 1 on the other) of these '' paired " units in contact, and the 

 2 posterior pairs separated by the anterior gular granules (No. 

 68842) ; 14 to 17 scales between the chin shields and the edge of 

 the collar; 4 anterior preanals, 6 posterior; 7 or 8 femoral pores on 

 each side; 34 scale rows around the middle of the body; 48 to 52 

 segments from the occiput to the base of the tail; two supraoculars 

 (sic/); 8 to 10 large collar scales; blackish brown above, slate 

 below. 



Genus BACHIA Gray 



BACHIA INTERMEDIA Noble 



1921. BacJiia intermedia Noble, Ann. New York Acad. Sci., vol. 29, p. 142 

 (type locality, Perico, Department of Cajamarca, Peru). 



Peru. — One paratype, No. 59927, collected at Perico, the type 

 locality, by the Harvard-Peruvian expedition in 1916. 



BACHIA PARKERI Ruthvcn 



1925. Bachia parkeri Ruthven, Proc. Boston Soc. Nat. Hist., vol. 38, p. 103 

 (type locality Chenapowu River, "on the upper Potaro River", British 

 Guiana). 



Thi's name was primarily based on five specimens from the type 

 locality. With these was associated a sixth specimen in the United 

 States National Museum, No. 65437, collected at Rio Tiquie, south- 

 eastern Colombia, by Mr. G. McCreagh. Its cliief characteristics 

 may be summarized as follows : Supraocular 1 ; superciliaries 2 ; inter- 

 parietal absent; upper labials separated from parietals; one pair of
