Remarks: Lioconcha polita is well represented in the offshore waters of New Caledonia but like 
Callista roseotincta is, with a single exception, absent from the Chesterfield Plateau. 
Lioconcha (Lioconcha) annettae Lamprell and Whitehead, 1990 
(Figure 2c-d) 
Lioconcha annettae Lamprell and Whitehead, 1990: 49, fig.4e-h; Lamprell and Whitehead, 1992: 
5р.545. 
Diagnosis: Shell with umbones inflated, similar to 1, ornata in shape, length to 38 mm. Colouf 
white, with black, chestnut-red or dark-brown chevron or hieroglyphic patterns; interior white; 
yellow centrally. 
Material examined: Plateau des Chesterfield (Corail 2: stn DW41, Irv; stn DW46, Irv; stn DW50,

Remarks: Lioconcha annettae is more attenuate posteriorly than L. ornata. Internally L. annettae has 
a sub-umbonal, orange-yellow colour patch, whereas L. ornata has a central, yellow colour patch. A 
comprehensive study of the annettae — ornata complex may yet show these forms to be conspecific.
