32. Solen variegatus. S. testa oblongo-ovata, anterius truncata, hiante ; 



cardine altero bidentato. 

 Shell oblong-oval, truncated before, and gaping ; hinge with two teeth 



in one valve. 



This elegant little shell is stained with purple and 

 orange colour, in a singular manner. The purple 

 passes* from the umbo more than half way down the 

 shell, and then turns forwards to cover the truncated 

 end. In the inside, the boundary of this stain is parti- 

 cularly apparent. Faint and narrow rays of purple 

 pass also from the apex to the margin, on the rounded 

 end of the shell, which, except from this interrup- 

 tion, is entirely of an orange colour. The hinge has 

 two teeth in one valve, and one in the other. The shell 

 is thin and pellucid, and gapes at the truncated end.

This species is particularly remarkable for two rows 

 of spines, which run from the apex to the anterior 

 margin of the shell ; the valves are dissimilar, the under 

 valve projecting in a slight degree over the other, ex- 

 cept at the truncated end. It is a white shell, trans-
