o 
East Indies, Philippines, Solomona. I have no materials. Herre’s 
largest specimen was 147 mm. long. He says of the species "It lives in 
swift mountain streams, clinging to the rocks and. slipping around and under 
them when disturbed, and is very difficult to dislodge or collect. It 
seems to congregate particularly on large bowlders which five it absolutely 
safe hiding places" 
I agree with Herre that the imperfect account by Bleeker for 
Platyptera sinensis , based on a Chinese "Figura dubiae exactitudinis" and its 
incomplete details "are scarcely sufficient to separate it from Rhyacichthys 
aspro" 
They are as follows: 
Depth 4 in length. Scales 32? in lateralseries. Body greenish' 
above. Snout violaceous. Fins, except dusky spinous dorsal, with golden 
rays variegated with brown spots.
