336 MR. G. A. BOULENGER ON THE [NoV. 29, 



Black dots irregularly disposed on the middle of the back ; 

 a dai'k lateral streak, formed of confluent vermicular spots, 

 enclosing light ocelli above the shoulder ; upper surface of head 

 without spots ; labials not dark-edged ; lower parts white. 



5, Male*'. — Shape of head and head-shields as in specimen 

 No. 1, but nasals forming a short stature behind the rostral, fourth 

 supraocular undivided, and lower border of subocular distinctly 

 shorter than upper. 



Collar even-edged, composed of 8 plates ; 32 scales between the 

 chin-shields and the collar ; gular fold very indistinct f. 



Body much depressed. Dorsal scales roundish-hexagonal, flat, 

 smooth, very faintly keeled on posterior part of back; 61 scales 

 across the middle of the body, 3 or 4 cori-esponding to a ventral 

 plate, 42 to the length of the head. Ventral plates in 6 longi- 

 tudinal and 25 transverse series. Anal bordered by a semicircle 

 of 8 small shields, the right median of which is twice as large as 

 the left. 



Hind limb reaching the shoulder. Scales on upper surface of 

 tibia rhomboidal, keeled, and a little larger than the dorsals, 8 

 transverse series of the former corresponding to 10 of the lattei'. 

 Femoral pores 18-18. 26 scales under the foiu-th toe. 



Caudal scales as in No. 1, but the whorls more distinctly uneqvial 

 in length, alternately longer and shorter ; 26 scales in the fourth 

 whorl. 



The specimen is much bleached ; in what i-emains of the mark- 

 ings it agrees with No. 1. 



The following measurements are taken from the five specimens, 

 in all of which the tail is either repi-oduced or partly broken off : —

The first and largest specimen, the male of which measure- 

 ments have been given by Camei-ano^, having smaller dorsal 

 scales (60 in a transvei-se series), less spinose caudal scales, and 

 22-21 femoral pores, cleai'ly represents Bedriaga's var. ■)nodesta§, 

 and is identical with the smaller male specimen referred to as 



* The specimen preserved in the British Museum. 



f Quite distinct in the other specimens. 



X The female specimen of which comparative measurements have been given is 

 evidently the one which has passed into Dr. de Bedriaga's private collection. 



§ Bedriaga divided the species into two varieties : modesta and rnd4s. The name 

 modesta had been previously proposed for a variety of L. rmtralis by Eimer.
