There is besides one specimen in the collection whose locality is 

 not given. At Sjopolse 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. 13 mm., Breadth of margin-zone 4 mm. In a specimen from 

 the entrance to Stordalen these measurements are respectively 39.5 mm., 

 22.5 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 

 POSSELT the species can attain a size of 40 mm. HAGG mentions a 

 specimen from the east coast 24 mm. long, and KNIPOWITSCH one from 

 Spitzbergen that was 28 mm. long. On the coasts of the White Sea 

 according to MIDDENDORFF it attains a size of 27 mm. On the northern- 

 most coasts of Norway SPARRE SCHNEIDER 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
