Cantor says a female he had for six months in confinement 

 produced eleven young, ones alive. A female however killed 

 by me in March near Kangoon contained six eggs (the rest 

 having been probably laid), so that additional observations are 

 desirable to determine if there is no error in one of the above 

 statements. Can Cantor's specimen have been the nearly allied 

 H. Jagorii described from Siam, which mainly differs from thef 

 present in having 128 ventrals only in place of 160 or there- 

 abouts ? 



Ferania, Gray.
