Dentalium agile, der forekommer paa de større dyb 
langs vor vestkyst fra Stavanger til Lofoten, har en syd- 
ligere udbredelse end foregaaende art, idet den gaar til 
Ascention, Havana og Den mexikanske golf. Artens nord- 
grænse er Lofoten og New England. Den bathymetriske 
udbredelse er 60—2547 fy. Fossil er den funden i Italien 
og paa Rhodes.

along the west coast of Norway, from Stayanger to Lofo- 
ten, has a more southern distribution than the preceding 
species, as it extends to Ascension Isle, Havana, and the 
Gulf of Mexico. Its northern limit is at Lofoten and 
New England. Its bathymetrical distribution is from 60
