When in good condition with its spines not worn off it is seen to be 

 but a dark coloured variety of ducalis.

I do not think the fig. 34 given by Sowerby is sinensis, but a variety 

 of ducalis. Among the many specimens of sinensis that I have 

 examined, I have never seen one with the dark niaculations on the 

 umbonal region as in fig. 34.

A second specimen in the Britisli Museum is of the same colour, 

 light purple-brown, but its spines are not nearly so spathulate as in 

 the type specimen. 



Possibly a variety only o[ sinensis.

Shell subcircular, moderately solid, very conve.x above and 

 somewhat concave at area of attachment below, purple with white 

 nucleus and some whitish lines at the margins, these lines being 

 more conspicuous on the lower valve ; upper valve with about 

 sixteen longitudinal ridges, more or less prominent, bearing some 

 short vaulted spines, a few longer spines on the lower valve; 

 between the principal ridges are four or five very fine ridges or 

 striiie ; ligamental area somewhat produced, the umbones being 

 about II mm. apart; interior of shell white, with a narrow band 

 of dark purple encircling the margins of the valves. 



Maximum dimensions : Height, 70 mm. ; width, 62 mm. ; depth 

 or diameter, 27 mm. 

 Hab. ? 



A smaller specimen examined by me has more numerous ridges 

 (about twenty-five) and spines. The very convex upper valve and 

 different colouration separate this from variegahis. 



Named in honour of Monsieur E. Lamy of the Paris Museum.
