There is besides one specimen in the collection whose locality is 
not given. At Sjépélse Ness 7 specimens were taken, from other locali- 
ties we have 1—3 specimens, though most frequently only one. 
Several of the specimens are of pretty considerable dimensions. 
Thus one specimen from the winter harbour measures: Long. 31 mm., 
Lath. 18 mm., Breadth of margin-zone 4 mm. In a specimen from 
the entrance to Stordalen these measurements are respectively 39.5 mm., 
29.5 mm., and 6.5 mm.; and in one from Vestre Sund they are 41 mm., 
17.5 mm., and 5 mm. On the west coast of Greenland according to 
Possett the species can attain a size of 40 mm. HAce mentions a 
specimen from the east coast 24 mm. long, and Knirowirscu one from 
Spitzbergen that was 28 mm. long. On the coasts of the White Sea 
according to Mippenporrr it attains a size of 27 mm. On the northern- 
most coasts of Norway Sparre Scunemer has found that tonicella 
marmorea is most developed out off the coast; thus at Tromsoe it is 
27 mm. long and at Vardoe about 30 mm. However on the Bergen 
coast, where the species attains the same development as on our arctic
