OF NORTHUMBERLAND AND DURHAM. 71 



The animal scarcely differs from that of E mar g inula, having 

 similar short appendages on the sides between the foot and cloak. 

 In our individual there were five on each side. 



Captain Brown mentions the Northumberland coast as a habi-

Patella vulgata, Mont. Test. Brit. 475. 



On the rocks between tide-marks, common.

 thumberland ; this is the " var. 4, conica" of Brown's Illust. t. 

 20, f. 5.

 Patella vulgata, var. 3, albumina. Brown Illust. Rec. Conch- 

 63, t. 20, i. 12-14. 

 On rocks close to low-water mark, rather rare. 

 " I first noticed this very beautiful variety on rocks at Culler-
