Lossiemouth ; and Mr. Murray has found another on the fishermen's 

 lines at Burghead. The only British locality yet known for Scalaria 

 Grcenlandica, " off Duncansbay Head," where Mr. McAndrew dredged 

 fragments of it, if not within, is close on the borders of the district as- 

 signed to this list. 



Glossy Aclis, Aclis nitidissima, (Turritella nitidissima, Flem.) 

 Found in shell-sand, both from Burghead and Lossiemouth. Another 

 species may be looked for as an addition to this list, viz., A. Ascaris. 

 It has been found by Mr. Alder on the East coast, and by Mr. 

 McAndrew in Zetland. 



Polished Eulima, Eulima polita, (Phasianella polita, Flem.) A 

 small specimen, discovered by Mr. Macdonald, is now in the Elgin 

 Museum ; and a larger one was observed in Edward's collection, from 

 Banff. 



Two-lined Eulima, Eulima bilineat a, [Phasianella subulata, Flem., 

 E. subulata, Mac.) A small specimen was dredged by Mr. Mac- 

 donald in the Moray Firth, and two more have been found in 

 shell-sand from Caithness. The following species of Eulima have 

 a range, in the North and East coasts, including the Moray Firth, viz., 

 E. distorta, " Orkney, Aberdeen and Northumberland," and E. subu- 

 lata, " Zetland and Scarborough." 



Orange-filleted Chemnitzia, Chemnitzia fulvocincta, (Turritella 

 simillima, Flem.) Mr. Macdonald has dredged one specimen of this 

 beautiful shell, alive, in the Moray Firth. A few other specimens, 

 chiefly broken, have been found in shell-sand. 



Indistinct Chemnitzia, Chemnitzia indistincta, (Turritella trun- 

 cata, Flem.) Dredged alive, off Lossiemouth, by Mr. Macdonald. 

 Not unfrequent among shell-sand. 



Unidentate or Single-toothed Odostomia, Odostomia unidentata, 

 (O. plicata, Flem.) This is by far the most common species of this 

 genus within this district. It is frequent among the shell-sand 

 of Caithness. Mr. Macdonald has found it alive on a dead bivalve, 

 dredged in the Firth, in 1853. 



Rissoa-like Odostomia, Odostomia Rissoides, (O. scajaris, Mac.) 

 A few specimens have been picked out of shell-sand from Caithness. 

 Mr. Macdonald has found it alive between tide-marks, at Burghead.

 Flem.) Two specimens of this rare shell have been found among a 

 quantity of shell-sand from the S.E. coast of Caithness.
