MALACOZOA. GASTEROPODA. PECTINIBRANCHIATA. 175 



turn almost entirely covers the rest ; the spire very short 

 or covered ; the aperture linear, extending the whole 

 length of the shell, with a notch at the anterior end ; 

 the surface glossy, without epidermis. 



Genus 1 . Cypraea. Cowrie. 



Animal elongated, spiral ; with two slender, tapering 

 tentacula, at the base of each of which externally is a 

 small eye ; the mouth with a long thin tongue beset 

 with small prickles, and extended into the abdomen ; 

 the foot elongated, large ; no operculum. 



Shell oval, very convex above, convolute ; with the 

 aperture longitudinal, linear, having a recurved notch at 

 each end, the lips denticulate or grooved, the outer in- 

 volute ; a longitudinal dorsal mark left by the margins 

 of the mantle. 



1. Cyprcea Europcea. European Cowrie. 



Shell ovate, very convex above, with numerous transverse 

 grooves ; the spire covered ; the aperture linear, both lips 

 denticulate, the outer involute, posteriorly extended beyond 

 the spire and curved ; the lower surface white, the upper grey 

 or purplish-grey, with three dusky spots. Length five-twelfths 

 of an inch, breadth three-and-a-half. 



There is a smaller variety, similar in form, but with the 

 upper surface flesh-coloured without the dusky markings. 



Both kinds occur along the coast, but are uncommon. 



Found by Miss Marion Macgillivray, in the Autumn of 

 1841, at Don mouth; by Mr. Davidson, in the following Win- 

 ter. I have specimens obtained at Collieston ; Mr. Murray 

 has gathered it on the coast of St. Fergus, Fraserburgh, and 

 Peterhead; and Miss M.icgillivray at Gamrie. Mr. Gray 

 has also sent me numerous specimens found about Peterhead. 

 I have not, however, seen this species alive.
