are brown instead of black, or more or less effaced. Largest 

 male 69 millim. from snout to vent, largest female 60. 



7 males, 10 females, 1 young. 



C) Uniform greyish brown, greyish green,, or olive. Largest 

 male 70 millim. from snout to vent, largest female 61. 



17 males, 13 females, 3 young. 



As regards the form and scaling there are no variations cor- 

 responding with the coloration, but it may be convenient to use 

 the three categories for the purpose of recording the result of my 

 examination. 



A) Number of scales across the middle of the body: 67 to 74 

 in males, 65 to 76 in females; number of femoral pores on each 

 side : 23 to 26 in males , 23 to 27 in females ; number of lamellar 

 scales under the fourth toe: 30 to 34 in males, 30 to 36 in 

 females. 



In 7 males and in 8 females the first supratemporal forms a 

 suture with the fourth supraocular on both sides, whilst in some 

 others it is so on one side only. One male and one female have, 

 on one side, five upper labials anterior to the subocular. One male 

 has two regularly superposed postnasals on one side, and this 

 anomaly occurs on both sides in one of the young. As in the 

 following categories, the masseteric disc is sometimes large, some- 

 times small, sometimes completely broken up into granules. 



B) The numbers recorded above are respectively as follow: 

 71 to 79 in males, 70 to 77 in females; 22 to 28 in males, 

 20 to 25 in females; 32 to 36 in males, 31 to 34 in females. 

 The first supratemporal is in contact with the fourth supraocular 

 in 5 males and in 7 females ; one female has five anterior upper 

 labials on both side, whilst in another female and in two males 

 it is so on one side only; one male has three anterior upper 

 labials on both sides. 



C) Numbers: 71 to 78 in males, 68 to 77 in females; 

 23 to 28 in males, 22 to 25 in females; 32 to 37 in males, 

 31 to 35 in females. 9 males and 11 females with the anterior 

 supratemporal in contact with the fourth supraocular ; one male and 

 two females with five anterior upper labials on one side, one 

 female with this number on both sides ; one male with two super- 

 posed postnasals on both sides. 



Taking the whole series of specimens together I find the am-
