Mollusks. 4461 



The present difference, however, between the Molluscous Fauna of 

 Dublin and of Moray, as shown by the next two lists, will probably 

 get more marked than otherwise, as these two so widely separated 

 localities continue to be explored by naturalists. 



Species not uncommon in the neighbourhood of Dublin, but rare or 

 not found at all in the Firth or Province of Moray, viz.: — Solen mar- 

 ginatus, Syndosmya alba, Lepton squarrosum, Ostrea edulis, Trochus 

 umbilicatus, Phasianella pulla, Rissoa inconspicua, Cerethium reticu- 

 latum, Scalaria communis, Chemnitzia elegantissima, Murex erinaceus, 

 Nassa reticulata, Trophon muricatus, Mangelia costata, Philine aperta. 



Species that are rare or that are not found at Dublin, but not un- 

 common in Moray, viz. : — Cochlodesma praetenue, Kellia rubra, Unio 

 margaritiferus, Anadonta cygnea, Leda caudata, Pinna pectinata, 

 Trochus Helicinus, Littorina neritoides, Rissoa punctura, R. rubra, 

 Skenea planorbis, Natica Montagui, Cylichna cylindracea, C. trun- 

 cata, Bulla Cranchii, Philine scabra, Aplysia hybrida. 



Specimens, collected from the Firth and Province of Moray, of all 

 the testaceous species enumerated in this paper, are now placed 

 in the Elgin Museum, except the following, viz. : — Tellina Donacina, 

 Nucula nucleus, Pecten varius, Crania anomala, Spinalis Flemingii, 

 Chiton Hanleyii, Pisidium fulvum, Puncturella Noachina, Caecum 

 glabrum, Eulimella Scilla3, and Akera bullata. Most of these eleven 

 are rare in any locality, but specially so in the Moray Firth. It is 

 hoped, then, that those who have it in their power to supply local spe- 

 cimens of any of these desiderata will do so, and the more readily, 

 when they know that their valuable donations go not to enhance any 

 private, but to complete a public collection, open to the stranger in- 

 terested in such pursuits, as well as to the resident student of the 

 provincial zoology. It need scarcely be here added that another 

 boon would be conferred by the gift of specimens of, or information 

 regarding other mollusks, whether testaceous or not, that have been 

 observed in the Province or Firth of Moray, but which are not 

 recorded in this paper as denizens of the district. 



An earlier opportunity should have been taken than at the close of 

 this paper, gratefully to acknowledge the assistance so obligingly 

 given during its compilation, by Robert McAndrew, Esq., of Liver- 

 pool. Though late, this acknowledgment, however, is not the less
