Solid shell up to about 5cm in length. White, yellow or brown in colour often heavily decorated with darker brown rays, streaks, blotches or waves. Inside of shell white or pale yellow sometimes with purple colouration. Very distinct radial sculpturing on shell and less prominent concentric sculpturing. Siphons fused together for almost their entire length.

Solid shell up to about 7cm in length. White yellow or light brown sometimes with rays or streaks of darker brown. Sculpture of radiating ribs and concentric rings give the a valves a very marked descussate appearance. Radial sculpture is as distinct or more distinct than concentric. Each valve has three cardinal teeth; the centre tooth on the left valve and centre and posterior on the right valve bifid.

Solid shell up to about 4cm in length. Pale yellow, dirty white or brown in colour sometimes with lines zig-zags or blotches of purple or brown. Sculpture of flattened concentric rings crossed by very fine radiating lines (difficult to see with the naked eye). Pallial sinus reaching the midpoint of the shell. Inside of shell white or cream tinged with yellow. Lunule bounded by a fine groove. Each valve has three cardinal teeth; the centre tooth on the left valve and centre and posterior on the right valve are bifid.

Soid shell up to 2cm in length. It is yellow white in colour obscured by brown periostracum. The inside of the shell is white. The surface of the shell is sculptured with radiating ribs and ridges which gives rise to a reticulate appearance in the middle of the valves.

Solid shell up to about 2.5cm in length. The outside is dirty white in colour; the inside is white. The surface is sculptured with obvious concentric ridges and grooves.

Thick solid shell up to about 4.5cm in length. The outside is dirty white in colour and the inside white. The pallial sinus reaches to the posterior end of the chondrophore. The surface is sculptured with concentric grooves but it still appears smooth.

Solid or brittle shell up to about 3cm in length. The outside is dirty white in colour and is white inside. The pallial sinus reaches to about half way along the lateral tooth. The surface is sculptured with concentric rings.

Brittle shell up to about 1.5cm in length. The right valve is slightly larger than the left. Both inside and outside of shell is white. The surface of the shell is sculptured with fine concentric lines (?and irregular concentric undulations). The pallial sinus is deep.

Straight sided shell up to about 12cm in length. Yellow in colour with light brown periostracum. Shell sculptured with smooth concentric lines and prominent groove just behind the front margin, Growth stages clear.

Solid shell up to 6cm in length. Yellowish white in colour; inside is white. Periostracum light green or yellow. Sculpture of concentric rings and radial ribs. Pallial sinus relatively deep and is confluent with the pallial line for much of its length.
