considerably in the lepidosis, more or less according to the 

 districts it inhabits, and has, in consequence, given rise to 

 the establishment of a certain number ot species, untenable as 

 such. However, with a la)ge material (I have carefully 

 examined about 350 specimens) it is just possible to draw up 

 detinitions justifying the rett-ntion of some of these forms, 

 whilst degrading them to a subordinate rank. 



The typical Ophiops eler/ans was founded on specimens 

 from Transcaucasin, in which, according to Boettger, the 

 number of scales and plates round tlie body vai'ies between 

 34 and 40 *. Those examined by me are froin Asia Minor 

 (Angora, Kaisarieh, Albistan, Giaour Dagii). 



The varieties which 1 recognize are four in number. 

 Their characlers are contrasted with those of the typicnl form 

 in the following synopsis, inle:idcd to apply to scries (jf 

 specimens : — 



32 to 41 (usually 34 to 40) scales and ])lates round 

 middle of body; 7 to 13 (usually 9 to 12) 

 femoral pores oa each side ; collar distinct only 

 ou tho sides ; occipital small or very small .... Forma typica. 



23 to 34 scales and plates round middle of body ; 8 to 

 12 (usually 9 to 11) femoral pores on each side; 

 collar distinct only on the sides ; occipital small 

 or very small Var. ehrenberf/ii. 



30 to 37 (usually 31 to 36) scales and plates round 

 middle of body; 8 to 11 (rarely 12) femoral 

 pore? on each side ; collar often distinct, some- 

 times free across the throat; occipital rather 

 large, sometimes 2 to 2^ times the width of the 

 interparietal Y&v. jtersicus. 



30 to .34 scales and plates round middle of body ; 11 

 or 12 femoral pores on each side; nostril be- 

 tween 3 shields, a single postnasal being present. Var. inizolepis. 



38 to 40 (usually 40 to 4G) scales and plates 

 round middle of body; 10 to 16 (usually 11 to 

 lo) femoral pores cyi each side ; collar and gular 

 fold often distinct ; occipital small or very small. Var. nc/dueten. 



Var. elirenberyii.

As has been pointed out by Boettger, the specimens from 

 Western Asia Minor and the Southern Sporades differ fr )m 



* Having counted them in 70 specimens from Angora, 1 find 16 speci- 

 mens with 36 scales and plates, 12 with 37, 11 with 38,8 with 40, 7 with 

 39, 6 with 3.'"), 6 with 34, 2 with 33, 1 witli 32, 1 with 41. 10 femoral 

 pores in 58, 11 in 46, 9 in 22, 12 in 9, 13 in 4, 8 in 1.
