278 Mr. G. A. Boulenger on new 



side. 25 to 27 lumellai- scales under the fourth toe. Green 

 or olive-grey above, uniform or with small black spols, 

 sparsely scattered on the back, more crowded on tlie sides, 

 sometimes (in a single female) forming a regular vertebral 

 series ; upper surface of head uniform green, olive, or brown ; 

 lower parts yellow, greenish, but not blue, on the throat and 

 on the sides of the belly. Young brown or olive, with three 

 white longitudinal streaks on the back, traces of which may 

 be preserved in the adult; black spots may be present 

 between them ; a white streak on each side of the neck, 

 from the tympanum, continued on each side of the body 

 or breaking up into two series of round spots; another white 

 line along each side of the belly. 



From snout to vent, $ 102 mm., $ 95 ; tail, ^ 190,

This form connects tlie var. stn'gafa with the typical 

 L. viridis, and especially the oriental specimens on which 

 the name var. vaillanti, Bedr., has been bestowed, agreeing 

 with the latter in the temporal scutellation and the reduction 

 in the number of superciliary granules, with the former in 

 the presence of a light vertebral streak in the young; it 

 differs from both in the lepidosis of the body, in respect 

 to which it approaches L. priticeps. 



This variety is described from eight specimens obtained 

 by the late Mr. B,. B. Woosnam on tlie South Coast of the 

 Caspian Sea, and from one young obtained by Mr. K. T. 

 Giinther at Bash Nurashin, N.W. Persia, which I had 

 referred to the var. Urigata (Journ. Linn. Soc. xxvii. 1899, 

 p. 378). 



Iclin oiropis tanganicana. 



Form and lepidosis as in /. capensis, Smith, but upper 

 head-shields rather feebly striated and the four super- 

 ciliaries in contact with the four supraoculars, only 3 or 4 

 small granules intervening between the second and third 

 superciliaries and the supraoculars, and lower nasal but 

 narrowly in contact with the rostral. 36 scales and plates 

 round tlie middle of the body ; ventral plates in 8 longi- 

 tudinal and 25 transverse series. 11 or 12 femoral pores on- 

 each side. 19 lamellar scales under the fourth toe. Bronzy 

 olive above, with a few small transverse blackish spots in 

 three longitudinal series on the nape and two on the body; 

 a black streak from the nostril to the eye, and another on 

 the edge of the mouth ; a white, black-edged streak from
