Vertebrae: 202 - 206. This species is distinguished by the following characters: elongate and unpatterned body and fins which is uniformly greyish brown; anus located just before mid-body, preanal length 2.0 in TL; head length 11.3 in TL; depth at gill opening 27.8 in TL; uniserial teeth, few, long and needle-like; mean vertebral formula 7-89-206 (Ref. 106142).
The 73.6 cm TL female was gravid and distended with 1.0-1.2 millimeter eggs (Ref. 106142).
