plates, 8 instead of 6. It further differs from the var. saxioola in 

 having the upper tibial scales considerably smaller than the dorsals. 

 In most respects it agrees with the var. chalybdea. 



A complete series of granules between the supraoculars and the 

 superciliaries ; 4 upper labials on one side, 5 on the other. Dorsal 

 scales faintly keeled. G-reen above, spotted with black, black on the 

 sides with round whitish spots.

In sending me the specimen, M. Lantz observed that it seemed to 

 him to be referable to Mehely's L. mixta, a supposed hybrid between 

 L. derjugini and L. saxicola ; but it does not at all agree with the 

 description,' the hind limb being shorter, the head more depressed, 

 the dorsal scales and the femoral pores more numerous, and the ventral 

 plates in 8 longitudinal series. 



M. Lantz, however, informs me that the latter character is not 

 constant, and that the femoral pores vary between 14 and 20. The 

 green on the back is remarkably vivid in life. It is therefore possible 

 that the names composita and mixta refer to the same form, which it 

 seems difiioult to define, and the separation of which from the var. 

 chalyhdea must be regarded as very doubtful.
