vividly lined across with very deep blue, and between every two blue 

 lines is a pink one, presenting an almost artificial contrast of colour.

Hab. ? 



This very chaste shell approaches somewhat in form to the Pleu- 

 rotoma carinuta. Gray, Griff. Cuv. An. King. {PL Kieneri, Doumet) ; 

 it is of a pale bluish ground, delicately corded and beaded with 

 bright ochraceous j'ellow. I only know of two specimens, one in 

 the collection of the Rev. Mr. Stainforth, the other in that of the 

 British Museum, purchased at the recent sale of Mr. Inwood's shells.

 apice acuto ; sexangulatd, anfractibus ad angulos longitudinaliter 

 tuberculatis ; olivaceo-fuscd, tuberculis tantum albis ; columelld et 

 aperturce fauce fused ; canali brevissimo.

I dedicate this shell with much pleasure to my friend Dr. Beck, cu- 

 rator of that noble patron of conchological science, the King of Den- 

 mark. It was found by Mr. Cuming in the locality above cited 

 under stones at low water. The snowy- white tubercles which orna- 

 ment this brown six-angled shell at the several angles are veiy cha- 

 racteristic.

Mr. Cuming has selected two varieties of this shell, but they are 

 not of sufficient importance to require especial notice, 



BucciNUM ELEGANS. Bucc. testd ovato-conicd, acuminatd, ubique 

 subtilissime nodulosd et liratd, interdum longitudinaliter leviter 

 costatd ; luteo-albd, columelld, labro, et canali vivide aurantiis ;

 liim excavatd, labro serrato.

This very beautiful and distinct species may be easily recognised 

 by its bright orange mouth. The entire surface of the shell is very 

 finelv nodulated.
