The examples given below on the occurrence of dead shallow- 
water shells at considerable deptbs in tbe Atlantie off tbe Sabara 
and tbe Canary Islands and off tbe Azores are quoted from 
A. Locard: „Mollusques Testacés, Expeditions scientifiques du „Tra- 
vailleur‘^ et du „Talisman““. Unfortunately Locard bas in bis 
statement about tbe vertical distribution as little as Jeffreys, 
distinguisbed between living molluscs and dead shells. In regarding 
tbe vertical distribution of tbe living molluscs in otber tracts of 
tbe Atlantic it can be inferred that most of the forms mentioned 
below can not have been dredged in a living state at the recorded 
deptbs.
