 Josepli Sabine, Esq., Vice-President, in the Chair. 



Sonie Notės by J. B. Haivey, Esq., Corr. Memb. Z. S., vvere 

 read : they accompanied a colleclion of Sliells and Crustacea made 

 by the vvriler on the coast of Devonshire, near Teignmouth. The se- 

 veral specimens were exhibited. 



Ainong them \veie numerous individuals of CyprcBa Pediculus, Ci/p. 

 bullala, and Cyp. Arctica. Of ihe former there are two varieties, 

 one spotted and the other without spots. The spotted variety, Mr. 

 Harvey statės, is geneially smaller than the plain one, and is less pro- 

 duced on one side near the apex. 



Cyp. bullala is found in tlie šame localities as Cyp. Pediculus, but 

 it mav be doubted vvhether it is the young of that species : it is so 

 comparatively rare, that Mr. Harvey has diedged up only six speci- 

 mens of it, while he has collected more tiian a hundred of Cyp. Pedi- 

 culus : he possesses, moreover, yonng individuals of Cyp. Pediculus 

 of smaller size than specimens of Cyp. bullala. In the laiter the 

 whorls are more produced at the apex, and the shell is so delicate as 

 to be broken by even a slight fall. 



On Cyp. Arctica Mr. Harvey remarks, that although its size and 

 appearance are in favour of its being a young shell, he hesitates in 

 referring it to the immature condition of the unspotted Cyp. Pedicu- 

 lus : his principai ground for doubt is the exlreme rarity of Cyp. 

 Arctica. He inquires, however, whether the young animal may not, 

 perhaps, live deeply imbedded in the sand for a certain period before 

 it comes to the surface, and thus generally elude the search of the 

 conchologist until its shell bocomes matured? 



With the Shells Mr. Harvey had transmitted to the Society living 

 specimens of CaryophyUia Suūthii, Brod., the Torbay Mndrepore, 

 whose habits vvere described by Mr. De la Beche in the ' Zoological 

 Journal ' a few years since : these individuals died on the journey. 

 They are attainable only at the lowest spring tides. They may be 

 kept alive in sea water, changed every second or third day, by feed- 

 ing them with a vcry small piece of fresh fish scraped, and deposited 

 vvith a quill upon the animal, by which it is sucked in in a manner 

 exactly similar to that of Palypi. The colours of some individuals 

 are very vivid ; and aniong these green, blue, and blueish grey are 

 the most predominunt. Adhering to the CaryophyUia is occasionally 

 found the Pyrgoma AngUcum, Leach, which appears to occur in no 

 other situation. 



At the request of the Chairman, Mr. Thompson of Belfast exhi- 

 bited an immature specimen of the long-lailed Mnnis, Manis tetra- 

 dactyla, Linn., for the purpose of shovving that when very young,
