10 / 4 , st. 4, lat. 49° 38' N., long. 1 1° 35' W, 923 m., 

 sand and mud, temp. 9°2 C. One specimen with 

 broken shell. 



23 / 5 , St. 41, lat. 28° 8' N., long. 13° 35' W., 1365 

 m., yellow mud. One strongly eroded shell. 



The specimen from st. 3 is 38 mm. high and 23 

 mm. broad. According to Jeffreys, 5. lignarius may 

 on the British coast attain height of 58.3 mm. and a 

 maximum breadth of 38.1 mm., 1 ) while on the Scandinavian 

 coasts, according to G. O. Sars 2 ) and Odhner, 3 ) it attains 

 a maximum height of only 28 mm. It thus appears 

 to grow to a larger size off the British than off the 

 Scandinavian coasts. The opposite is the case with 

 5. puncto-stiiatus, which attains its greatest size, about 

 35 mm., in Northern Norway, and therefore apparently a 

 more northern species than S. lignarius.
