Body slender, depth 9.7-10.6 in SL Head short, length 3.9-4.2 in SL. Anterior nostril at end of short tube, about midway between upper margin of upper lip and eye, about 2 nostril diameters above upper lip; posterior nostril with raised rim, immediately before anterior margin of eye. Eye about equal to snout in adult. Mouth small and oblique; reaching to below middle of eye in male and below anterior quarter of eye in female; upper margin of upper jaw in line with middle of eye; teeth in upper jaw conical, those in outer row close-set; few smaller teeth anteriorly in second row; lower jaw teeth similar to upper jaw teeth, but with outer row teeth more wide-set; tongue tip truncate to slightly emarginate. Gill opening restricted to pectoral base. Head pores absent.
Body partly scaled; small patch of vertically elongate scales behind pectoral base on sides of belly, lateral line absent; longitudinal count 6-10, and isolated patch of few scales on caudal peduncle, sometimes extending forward in narrow wedge to under end of second dorsal fin, longitudinal count 3-14; rest of body including pectoral base, prepelvic area and belly naked; scales mostly ctenoid; longitudinal scales 10-24.
Two dorsal fins; first dorsal fin short-based with low rounded margin; all dorsal and anal fin rays usually segmented. Pectoral fin with rounded margin, reaching to point below middle of first dorsal fin. Pelvic fins fused to form large cup-shaped disc reaching to below end of first dorsal fin, well short of anus.

Size

To around 3.5 cm SL.

Colour

Transparent to pale brown, with row of about 9 small fawn markings along lateral midline, many vertically elongate; other fawn markings dorsally; thin black vertical bar from ventral margin of eye to posterior end of jaws; diffuse black spot behind posterior margin of eye and similar diffuse black mark on dorsoposterior margin of operculum. Fins mostly opaque; dorsal fins usually with black spots forming oblique lines, caudal fin sometimes with wavy vertical grey bars.

Biology

Females spawn demersal eggs.

Etymology

The species is "named in honour of the late Clive Errol Lord, Director of the Tasmanian Museum, and for fifteen years Secretary of the Royal Society of Tasmania, the most notable worker in systematic ichthyology since R.M. Johnston's time."
