COOKE : ON THE MACANDREW COLLECTION. 36 1 



Helcion pellucidum L. Anglesea, &c. 



Very fine specimens. 

 H. pellucidum L. Shetland. 



Smaller, thinner, the blue lines often indistinct or 

 wanting. 

 H. pellucidum L. Isle of Man. 



An intermediate form. 

 H. pellucidum L. var. Jsevis Penn. Isle of Man, &c. 



Labelled in error P. ccerulea, which is a variety of 

 P. vulgata. 

 Acmaea testudinalis Mull. Hebrides. 

 A. testudinalis Miill. Orkney. 



A single small specimen. 

 A. virginea Miill. Orkney. 

 Pilidium fulvum Miill. Loch Fyne, &c. 

 P. fulvum Miill. var. albida. Loch Fyne, &c. 



Included without notice on the same card. 

 Lepeta caeca Miill. Loch Fyne. 

 Propilidium ancyloides Forbes. Isle of Miill. 



Three dead and two living specimens only, 

 Puncturella noachina L. Loch Fyne, &c. 

 Emarginula reticulata L. Anglesea, &c. 

 E. rosea Bell. Weymouth. 

 E. crassa Sby. Loch Fyne and Carnarvonshire. 



Two specimens from each locality. The labels 

 were evidently misplaced, and I have transposed them. 

 The two larger specimens (three times the size of the 

 others) were labelled as if from Carnarvonshire, which 

 is most unlikely. The locaUty is the most southern 

 recorded, and it is possible that these specimens have 

 something to do with Jeffreys' remark in his appendix — 

 "Anglesea, Miss Roberts fide MacAndrew."
