sides by the glands on the före limbs, by longer snouts and 

 longer hind limbs, being the same differences we find between 

 young and old females. Thus, all the small females have 

 longer snouts and longer hind limbs than the large ones, ex- 

 cept one very large female that seems to have begun to lose 

 her female characters, obtaining instead those of the males 

 (a long snout and long hind limbs). 



The f ollowing table will prove the correctness of the above :

In this table I also give the average measurements of 

 the length of the före limbs, also these, though much less 

 evident, showing the same course of development as the 

 hind limbs. Any sexual difference is not to be found here. 

 the measurement of the male being completely the same as 

 in similarly sized females. 



The colour varies considerably; the back being brown, 

 brownish-gray, olive coloured, or even light gray usually with 

 some rather indistinct dark spöts. The lateral glands are 

 of ten pure white but also sometimes dusky-coloured; the 

 lower light parts are in some specimens clouded with brown 

 or gray; the hind hmbs more or less distinctly black-barred. 

 As BoTJLENGER rcmarks, the white on the upper lip disap- 

 pears in the largest specimens but may be also wanting in 

 some middle-sized examples. There is no difference in colour 

 between the male specimen and the females to be detected. 



^ In this number the measurement from the smallest speeimen is 

 ot counted, being so exceptionally low (68).
