dorsal tubercles than the males. The females from Tandjong 

 (S.E. Boi^neo) and from Akar River (Sarawak) show the typical 

 coloration above described. 



A female specimen from Mt. Kuala Lumpur (Selangor) shows 

 an interesting variation. The general colour is a dark gi'ey, 

 a.pproaching brown. The upper part of the head, of the back, 

 and of the tibia shows no yellow spots, but the sides of the body 

 and of the limbs, as well as the upper part of the thighs, have 

 round or oval spots pretty distant from one another. These spots 

 are of a fine yellow colour, with brown border. Similar but 

 longer spots may be found on the throat and on the anterior 

 part of the chest. 



A female from Akar River (Sarawak) shows irregular and in- 

 distinctly disti'ibuted spots. The yellow colour is prevalent on 

 the back ; the sides are marbled yellow and black ; the belly is of 

 a dirty yellowish colour.
