shell attributed to this species from the Tertiary rocks of Belgium turns out to be referable 

 to the Mannia Nysti of Dewalque.

— septata, Philippi. According to Jeffreys, &c. 



The living form of this very remarkable species was first discovered by Loven, who 

 gave a good description of it, but without a figure. In 1855 I made good the omission. 

 It was then believed to be a rare species, but was subsequently dredged by Mr. Jeffreys 

 and Dr. Carpenter, nearer the Orkney and Shetland than the Faroe Isles, in a depth of 203 

 to 345 fathoms. Also outside the Channel Slope, or " Chops of the Channel." Coasts of 

 Norway (Loven, Sars, and others), in from 150 to 300 fathoms. ' 



It occurs fossil in Sicily, Rhodes, Norway. Mr. Jeffreys is of opinion that the shell 

 here noticed is the Terebratula septata of Philippi, a fossil occurring in the Pliocene rocks 

 of Sicily; but as Sig. Seguenza is of a decidedly different opinion, and as some uncertainty 

 may still prevail as to what really was Philippi's species, I have preferred retaining, at 

 any rate provisionally, the name given to the recent form by Prof. Loven.

This species is now well known, and has been correctly described and illustrated. 

 Mr. Jeffreys dredged a fresh and perfect specimen in 90 to 100 fathoms, about thirty- 

 five miles north-north-west of Unst, but it occurs more plentifully in Spitzbergen.
