 Schleg. Ess. pi. 12. f. 1-3 ; Dum. ^ Bibr. vii. p. 590.

 and sixth touching the orbit; anterior ocular one, posterior

 red (in spirits olive-brown) triangular blotches, separated one 

 from the other by black spots, and becoming indistinct towards 

 the middle of the body ; ventral plates either uniform yellowish 

 or dark-edged. 



Cantor (Catal. of Malayan Rept. p. 89) is wrong in identifying 

 this species with Tr. umbratus; the specimens in the British 

 Museum, one of which is named by Herr Schlegel from the 

 Ley den Museum, ]}rove the difference in number and dispo- 

 sition of the upper labials.
