St 2. 808 f77is., and St. 19. 1360 f77is. are situated on the 
slopes from the platform west of Ireland to the deep water in the 
Atlantic. Especially at St. 19 the slope of the hottom is exceedingly 
steep. The distance from St. 2 to the 100 fathom line is ahout 
60 miles, from St. 19 about 25 miles. 
St. 4, 6, 7, 9, 13. 14, 18 have their position on the platform 
west of Ireland where the bottom slopes very gradually from the 
shore to a depth of from 200 to 300 fms. The distance to the 
100 fathom line is from St. 4 ca. 100 miles, from St. 13, 14, and 
18, 15 to 20 miles. St. 6 and St. 7 are about 50 miles off the 
50 fathom line, and St. 9 about 100 miles off the coast. 
The findings of adult specimens of Tellina baltica and Littorina 
obtusata at St. 9 are very noticeable. 
St. 13 and St. 14 are situated north of the Porcupine Bank. 
There is a possibility that all the named shallow-water shells from 
these stations may live on the Porcupine Bank at present. 
St. 15. 422 fms. is about 50 miles off the 100 fathom line. 
At the present time the species has its Southern limit at the Færoes, 
and Bergen in Norway.
