Young specimens with remains of the larval tail measure as 

 much as 30 millim., whilst a female ready to spawn measures only 

 41. The eggs in the oviduct are very large and comparatively 

 few, the diameter of the vitellus being 2 millim. 



Founded on a single specimen from Matang, Borneo, this 

 species has since been found on Mount Kina Balu, Borneo, and 

 at Gunong Tahan, Pahang, in the Malay Peninsula, at an altitude 

 of 5200 feet.
