Distribution. Curt/////// echinatum is distributed along Europe from West Finmarken to 

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

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

 of Iceland. In the Mediterranean, including 



the Adriatic and Sea of Marmora, a varietv 4 



(var. mucronata) occurs. Its vertical distribu- 

 tion is ca. 5 — 80 fm. ') 



Remarks. The very small specimens 

 of this species are not easy to recognize at 

 first glance; as fig. 3 shows, the antero-dorsal 

 corner forms a sharp angle. During the

Carclium edule Linne. 

 [Iceland.] 



Dr. A. C. Job ansen has brought home a left valve of C. cd?ile taken on the beach at Heimaey, 

 which is the largest of the Vestmanna Islands at South-Iceland; the valve is thick-shelled and 33.5 

 long. As the species has not been found elsewhere at Iceland, we must be careful in drawing con- 

 clusions from this isolated find; this valve may have been brought to the islands with ballast or in 

 other ways.-') 



[The Faeroes.] 



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

 the Faeroes, but from an examination of the specimens from the Faeroes labelled "Cardium cdulc' 



") According to Jeffreys the Porcupine Expedition of [S69 has taken ii \V. of Ireland down to 1S3 I'm., but it is 

 not stated whether the specimens were living or not.
