Spirally-ribbed Odostomia, Odostomia spiralis, (also O. plicatula, 

 Mac.) Found in shell-sand, gathered at Portsoy, by Miss Pirie. It also 

 occurs among the shell-sand from Caithness. Among a set of speci- 

 mens forwarded to Albany Hancock, Esq., he identified and most 

 kindly named the above species of this most difficult genus. 



Cross-lined or Decussated Odostomia, Odostomia decussata, [Turbo 

 decussata, Flem.) A few specimens were picked out of the shell- 

 sand, gathered at Portsoy, by Miss Pirie. The following species of 

 Odostomia have been found both to the North and to the South of the 

 Moray Firth, viz. O. plicata, "Lerwick" and " Aberdeenshire ; " O. 

 insculpta, " Lerwick and Aberdeen." 



McAndrew's Eulimella, Eulimella Scillce, " In thirty-four fathoms, 

 Elgin," F. * H. 



Needle Eulimella, Eulimella acicula. Two specimens, most 

 probably of this species, were dredged off Lossiemouth by Mr. 

 Macdonald. 



Beaded Natica, Natica monolifera, (N. glaucina, Flem.) Not 

 rare. 



Alder's Natica, Natica nitida, (N. Alderi, Flem. and Mac.) Fre- 

 quent. A beautiful series of this pretty species has been collected at 

 Burghead by Mr. Murray. 



Sordid Natica, Natica sordida. Mr. Macdonald has dredged one 

 specimen off Lossiemouth ; Mr. Duff procured another from a Lossie- 

 mouth fisherman. Both are now in the Elgin Museum. 



Montagu's Natica, Natica Montagui, (N. rufa, Flem. and N. 

 rutila, Mac.) Not rare, although far from being so frequent as 

 N. nitida. 



Helicine Natica, Natica Helicoides. One from a fish-stomach, 

 1850. Mr. Martin, in 1853, met with another in a fishing-boat at 

 Lossiemouth. 



Striated Velutina, Velutina laevigata, (V. striata, Mac.) Frequent. 

 Sometimes cast ashore in considerable abundance, as on the sands 

 east of Lossiemouth, March, 1853. 



Flexible Velutina, Velutina Jlexilis, (Bulla Jlexilis, Flem., Corio- 

 cella Jlexilis, Mac.) Very rare. A specimen, found by Mr. Martin 

 near Lossiemouth, is now in the Elgin Museum. 



Haliotis or Ear-shaped Lamellaria, Lamellaria perspicua, [Sigare- 

 tus Haliotideus, Flem.) The only locality, as yet observed, for this 

 mollusk in the Moray Firth is Burghead ; the supposed Ptoroton of 

 Ptolemy, the Eccialshacca of Torphceus. Mr. Murray, who dis- 

 covered it, states that it is by no means rare.
