356 Rev. Canon Norman — A Month on 



34. Trophon clavatus^ G. O. Sars. 



Eodberg, 250-300 fathoms. Two living examples of this 

 very rare shell were procured. They very closely accord 

 with the two specimens figm-ed by Sars in character and even 

 in size, the one having a length of 15i millim., the other 

 11 millim.; of these total lengths, in the first the mouth and 

 its very long canal occupy 1\ 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 M. clathratus, and is 

 also wholly different from M. vaginatuSy Christ, and Jan, of 

 the Mediterranean. 



35. Trophon harvicensis, Johnston. 

 Specimens small, in 150-300 fath. 



36. Trivia europiea, Mont. 

 10 fath. 



37. Aporrliais pes-pelecaniy Linn. 

 Trondhjem, 10-30 fath. 



38. Bittium reticulatum^ Da Costa. 

 Larainarian zone. 



39. Lovenella vietula, Lov^n. 



Eodberg and Trondhjem, 150-300 fath. 



40. Lceocochlis Macandi^ece, H. Ad. 

 Eodberg, 250-300 fath. 



41. Cerethiopsis costulata^ Moll. 



Eodberg and Trondhjem, 150-300 fath. ^ 



42. TricJiotropis boreah's^ Brod. & Sow. 

 Trondhjem and Eodberg, 5-30 fath. 



43-45. Littorina littorea^ Linn., L. rudis^ Maton, and L. oh- 

 tusata^ Linn. 



The last typical and not showing any approach to L.palliata. 

 I have not seen the latter from south of Tromso. Specimens 

 taken at the Lofoten Islands in 1890 were the former ; nor 

 has G. O. Sars met with L. palliata at those islands.
