Distribution. C.fasciatum is distributed along the whole of Europe, from the western part of 

 the Murman Coast to the Canary Isles and the Eastern Mediterranean; through the Belts it reaches 

 down into the Western Baltic. Towards the west it extends to the Fseroes and Iceland. G. O. Sars 

 estimates the vertical distribution to be from 10 — 180 fm. 1 ), but at the Faeroes it reaches up to 5 fm. 

 (cf. above), according to Sparre Schneider it comes into 3 fm. (at Tromso) and according to 

 C. G. Job. Petersen into 2 fm. in the southern Kattegat. 



Remarks. Cardium fasciatum appears to be a very variable species at Iceland and the 

 Fa:roes. It occurs in two forms: 



a. The shell short, strongly ventricose, with the posterior area sloping quickly downwards and 

 as if abruptly separated from the middle area by a keel (PI. Ill, figs. 9a — b). 



b. The shell somewhat elongated (especially posteriorly), not much tumid, with the middle 

 area grading without sharp boundary into the posterior area (PL III, figs. 9c — d). 



Between these extreme forms, however, there are transitions. So far as my experience goes, 

 the tumid variety is usually an oceanic form, whilst the elongated and flat variety is found in fjords; 

 but both may be found together in the latter 2 ). 



) Jeffreys states, that the "Porcupine" has taken it W. of Ireland at a depth of SoS fm., but as usual without 

 tating whether living specimens or dead shells were found. But the statement itself is perhaps erroneous. 



Whilst the tumid form is predominant at Iceland and the Faeroes, I find the flat form by far the commonest in
