422 Deep-sea Trawling off the S.W. Coast of Ireland : 
Bulla semilevis, Seguenza. 
From 1000 fath. 
Cylichna (Sao) ovata, Jeffreys. 
From 1000 fath. 
This species was obtained in various parts of the North 
and West Atlantic in from 350 to 1000 tath. by the ‘ Porcu- 
pine’ and ‘ Challenger’ expeditions. 
SCAPHOPODA. 
Dentalium candidum, Jeffreys. 
From 1000 fathoms. 
One of the two specimens obtained is very fine, and con- 
siderably exceeds the dimensions quoted by Jeffreys. It is 
85 millimetres in length (=8 inches), and 8 in diameter at 
the aperture. ‘The longitudinal strize in this example can be 
traced from the apex along about half the length; and at a 
little more than an inch from the broader extremity a strongly 
marked reparation of an injury is visible, the result of an 
accident or the attack of an enemy. 
This species was first obtained by the ‘ Valorous’ expe- 
dition in from 410 to 1750 fath.; it was subsequently dredged 
at several stations off the west and south of Ireland by the 
‘Porcupine’ expedition at depths ranging from 420 to 
2435 fath. 
Cadulus Olivi, Scacchi. 
From 1000 fath. 
Two specimens from the above depth agree exactly with 
others in the Museum obtained by the ‘ Porcupine’ expe- 
dition, which Jeffreys* associated (and probably correctly) 
with this species. The latter were dredged off the west 
of Ireland in 1230 fath., and south of Ireland in 539 fath. 
PELECYPODA. 
Montacuta substriata, Montagu. 
From 50-60 fath. 
As usual around the British coasts, these specimens were 
dredged attached to the spines of Spatangus purpureus.
