325, 



Text-fiff. 99. 



follows : — The length of each specimen (in millimetres) is taken 

 from the end of the snout to the posterior extremity of the vent. 

 O means presence ( + ) or absence ( — ) of the supraocular spot 

 (on the upper eyelid). 



P, the spot on the parotoid gland. 



S, spot or spots on the snout. 

 OP, OS, whether the above- 

 mentioned spots are confluent or 

 not. PB, whether or not the 

 spot on P is confluent with one 

 on the body. In cases where the 

 two sides differ, the initials R 

 (right) and L (left) indicate the 

 discrepancy. 



Sp., total number of spots on 

 the upper surface of body (to 

 a line connecting the posterior 

 borders of the hind limbs), which 

 is divided into four conventional 

 segments, numbered I, II, III, 

 lY ; under each of the latter 

 figures, the spots pertaining to 

 each segment are given. These 

 spots are numbered 1, 2, 3, &c., in 

 the order shown on the diagram ; 

 in case of absolute symmetry, the 

 spots are numbered from right to 

 left. 



A stands for the vertebral area, 



, _ J bearing the two median rows of 



\ ^ ^ ___ _' / glands. B (right and left) for the 



- ^ ' " area between A and ; (right 



and left) for the area occupied by 

 the series of large lateral glands ; 

 D for the area between the latter 

 and the limit of the belly (taken 

 from an imaginary line connect- 

 ing the lower border of the axil 

 with the groin). In column D, 

 right and left sides are separated 

 by a — , the figures referring to 

 the number of spots on each side 

 (spots confluent with the ventrals 

 and dorsals not reckoned), not to 

 the individual spots as in the 

 columns A to C. 

 G, pi-esence ( + ) or absence ( — ) of yellow spots on the chin and 

 gular I'egion. 



Y, on the ventral region of the body.
