356 Rey. Canon Norman—A Month on 
34, Trophon clavatus, G. O. Sars. 
Rédberg, 250-300 fathoms. ‘Two living examples of this 
very rare shell were procured. They very closely accord 
with the two specimens figured by Sars in character and even 
in size, the one having a length of 155 millim., the other 
11 millim.; of these total lengths, in the first the mouth and 
its very long canal occupy 7} millim., in the latter 6 millim. ; 
on the larger five varices are visible on the body-whorl when 
viewed from the front, on the smaller six. The varices are 
projected considerably on the upper part of the volutions in 
triangular processes outwards, but scarcely at all upwards. 
It appears to me quite distinct from MM, clathratus, and is 
also wholly different from JZ. vaginatus, Christ. and Jan, of 
the Mediterranean. 
35. Trophon barvicensis, Johnston. 
Specimens small, in 150-300 fath. 
36. Trivia europea, Mont. 
10 fath. 
37. Aporrhais pes-pelecant, Linn. 
Trondhjem, 10-30 fath. 
38. Bittium reticulatum, Da Costa. 
Laminarian zone. 
39. Lovenella metula, Lovén. 
Rédberg and Trondhjem, 150-300 fath. 
40. Leocochlis Macandree, H. Ad. 
Rédberg, 250-3800 fath. 
41. Cerethiopsis costulata, Moll. 
Rédberg and Trondhjem, 150-300 fath. 
42. Trichotropis borealis, Brod. & Sow. 
Trondhjem and Rédberg, 5-30 fath. 
43-45. Littorina littorea, Linn., L. rudis, Maton, and L. ob- 
tusata, Linn. 
The last typical and not showing any approach to Z. palliata. 
I have not seen the latter from south of ‘'romsé. Specimens 
taken at the Lofoten Islands in 1890 were the former ; nor 
has G. O. Sars met with ZL. palliata at those islands.
