L.l(pore)89-99.Depth of body contained in standard length 4.4-5.8(5.2), width of body 6.6-7.9(7.3). length of head 4. 1-4.6 (4.3), length of caudal peduncle 7.3-8.8 (7.9). depth of caudal peduncle 9.9-11.8(10.9), depth of head contained in its length 1.9-2.0(2.0), width of head 1.2-1.4 (1.3), length of snout 1.7- 1.8 (1.8), diameter of eye 6.8-7.8(7.1), width of interorbital space 2.5-2.9 (2.7), depth of caudal peduncle contained in its length 1.4-1.5(1.4). width of mouth contained in width of head 3.2-3.6 (3.3).The new species is most closely similar to C. fascicauda Nichols its alternate black and white stripes and pattern of caudal, but differs from the latter in 1. having wider black bands in lateral lines, 2. having shorter caudal peduncle and 3. having a larger naked region of abdomen.
