 a purplish border all round.

The colouring of Sowerby's figure is ridiculous, the yellow ground- 

 colour being purely imaginary. The type is whitish towards the 

 umbones, but light purplish red elsewhere, rayed with a much 

 darker tint, the rays being narrower than as depicted in the 

 figure. 



The single specimen from Torres Straits has the ground-colour 

 light purplish red like the type, but the slightly elevated rays are 

 white instead of being darker.
