Odontophorus Bal/iviani, Gould in Proc. of Zool. Soc., Part XIV. p. 69- 
For our knowledge of this remarkably fine species we are indebted to the researches of Mr. Bridges in 
Bolivia. To no one member of the genus to which it belongs, need it yield the palm in size, or in the 
beauty and colour of its markings. At the request of Mr. Bridges, I have named it Ballimani in honour of 
General Ballivian, President of the Republic of Bolivia, who afforded him every facility in his power for 
the prosecution of his researches, and whose love of science renders him worthy of such a compliment. 
Habitat. The forests of Cocapata in the Department of Cochabamba, in Bolivia. 
The figures are of the size of life, from specimens procured by Mr. Bridges.
