Gill rakers onthe first arch 10--18.Depth of body 7. 99 (6. 93--9. 17)in baby length, head length 5. 09 (4. 51--5. 61 ); lengthof caudal peduncle 5' 12 (4' 76--5. 61 ),depth of caudal peduncle 12' 94 (10. 77--15. 83 ), snout2. 39 (2. 19--2. 72 ) in head length, eye diameter 6. 56 (5. 0--9. 75 ), interorbital space 3. 85(3. 21--4. 71 ), length of caudal peduncle 1. 0. Depth of caudal peduncle 2. 53 (2. 01--3. 16)inlength of caudal peduncle.The new species is similar to the species Triploph y$a (TriplOPhysa ) breVicauda (Herzen-stein),but differs from the latter in the origin of ventrals obviously in advance of dorsal fin,ventral fin far from the anus and the head length equal to the length of caudal peduncle.
