Distribution. Cardiiiiii cchiiiatxm is distributed along Europe from West Finmarkeu to 

 Madeira and the Canary Isles, it reaches down to the south-western Kattegat and the Sound (Hveen). 

 Towards the west it extends over the Fasroes to the south-eastern, southern and south-western coasts 

 of Iceland. In the Mediterranean, including 



tlie Adriatic and Sea of Marmora, a variety 4 



(var. iiiucronata) occurs. Its vertical distriliu-

 other ways.^)

According to Morch (Vidensk. Medd. Naturhist Foren. Kbhvu. 1867, p. 93) C. rdiilc lives at 

 the Fteroes, but from an examination of the specimens from the Fseroes labelled "Cardiuvi cdulc" 



1) According to Jeffreys the Porcupine Expedition of 1S69 has taken it W. of Ireland down to 183 fni., but it is 

 not stated whether the specimens were living or not. 



2) Mohr's C. edule (Forsog til en Islands Historie, 17S6, p. 12S) is identical with CarJinm cilintiim Fabricius.
