Doris cameroni (J. K. Allan, 1947)

Description

A small dorid reaching about 25 mm (1 inch crawling). The dorsum is yellow with numerous large, raised, rounded pustules and smaller pustules between them; the top of each pustule is tipped with a small blackish-brown spot, giving the back a finely speckled appearance. A large dark patch runs along the dorsal midline and a smaller one lies immediately before the gills. The rhinophores are conspicuous, lamellated, and white. There are only six gills, very bushy and tripinnate, also white. The foot is broad and the oral tentacles cylindrical and prominent. In preservative the rhinophores and gills retract deeply into the mantle.

Distribution

Type locality: Angourie Pool, at the mouth of the Clarence River, northern New South Wales, Australia.

Etymology

The specific epithet cameroni honours Mr. A. A. Cameron, the Australian shell collector based at Harwood Island on the Clarence River, who supplied the type specimen.

Remarks

The describer concluded that the species could not be matched with the Californian Archidoris montereyensis or with several other regional dorids, and erected it as a new species.
