56Q Scientific Notices. 



Shell ventricose, opake, with regular, raised striae : aperture with 

 four or five plaits, two of which are larger. 



Our cabinet presents the following varieties: 



a. Vlicis quatuor^ duabus mediis minoribus. 

 With four plaits, the two middle ones less. 



b. Plicis quinque^ iribus mediis minoribus. 

 With five plaits, the three middle ones less. 



c. Plicis quinque, tribus inferioribus minoribus. 

 With five plaits, tlie three lower ones less. 



At Torquay we found a perfectly formed specimen of the Swiss 

 Cl. parvuta^ mentioned by Dr. Leach. It is much less and more 

 slender than 67. rugosa of Draparnaud, and is very faintly striate, 

 or smooth, except on the lower volution. The two possessed by 

 the Provost of Eton, are no doubt the same. The aperture re- 

 sembles that of Cl. rugosa. 



Pupa edentula is by no means uncommon, under stones, in dry 

 situations. 



The Roxania Cranchii h found in Torbay, and at Scarborough, 



Trochus Montacuti is found plentifully in Torbay and the Eng- 

 lish Channel, and at Scarborough. 



The Scaphander caienatus, of Leach, with its gizzard, is 

 dredged up at Scarborough. 



Several specimens of the Tritonia Cutacea were last winter cast 

 on shore at Padstow, in Cornwall. 



The Pileopsis Ungarica may eventually be considered as a 

 bivalve shell, of the genus liipponyx ; as in removing a living 

 specimen from an oyster, we observed a thin laminar under-valve, 

 which is now in our cabinet. The horse-shoe shaped muscular 

 impressions are, also, exactly similar to those of the Hipponyx. 



Montagu observes, that after the strictest enquiry, he had not 

 been able to fix the sulcated variety of Cyprcea Pediculus^ as a 

 decidedly British production. A living specimen was, however, 

 taken at Weymouth, and which we saw in the cabinet of Miss 

 Warn. If therefore, as Montagu inclines to think, the one with 

 the groove along the back, and that which has no groove, be dis-
