Description

(Form). Body elongated, and very much compressed throughout: greatest depth rather exceeding one-eighth of the entire length: thickness half the depth: head and back in one horizontal line; the former small, not more than one-ninth of the whole length, excluding caudal: snout more pointed than in the true Blennies; mouth small; lower jaw sloping considerably upwards; teeth minute: eyes placed rather high; the space between forming an elevated ridge: nape, behind the eyes, a little depressed: dorsal fin commencing a little behind the nape, at a distance from the end of the snout equalling one-eighth of the entire length, and extending quite to the caudal, with which it is continuous; all the rays simple and inarticulated, flexible, of the same height throughout, equalling scarcely more than one-sixth of the depth, projecting a little beyond the connecting membrane: anal commencing at about the middle of the whole length, likewise continuous with the caudal; the first two rays spinous; the rest articulated and branched: caudal rounded, with fifteen branched rays, and six simple ones shorter than the others, four above and two below: pectorals short, scarcely more than half the depth, rounded; all the rays articulated, and, except the first and last, branched: ventrals extremely small, scarcely one-third the length of the pectorals, reduced to a single spine united to one small soft ray of about its own length:

D. 77; A. 2/40; C. 15, and 6; P. 12; V. 1/1: vent exactly in the middle. (Colours). Deep olive, with a row of dark ocellated spots, varying in number, but generally from ten to twelve, along the line of the back, extending partly on to the dorsal fin: belly whitish: pectorals yellow.

Variety. Purple Blenny, Low, Faun. Ore. p. 203. " Reddish purple; fins lightest Likewise wants the spots on the back; instead of eleven, has only a single one, and that placed near the beginning of the back fin." Low.
