* " Rissoa fallax appears to be a Melania, of the sub-genus Eulima." — 

 Ed. Forbes. 



+ Only one broken fragment of this shell has been discovered, in a brick- 

 field, near Glasgow. I am doubtful, however, as to its being a fossil, as it 

 was given to me by a person who may have found it accidentally, or have 

 deceived me. None of the other unknown species are doubtful in this 

 respect. 



J This shell, found in the brick earth of Norfolk, which undoubtedly be- 

 longs to this formation, is a crag fossil, Sowerby, Min. Con. t. 110, f. 4. It is 

 given from the Tables of Organic Remains in Woodward's Geology of Nor- 

 folk. 



§ Found in an elevated marine deposit in the Isle of Man, by Mr Edward 

 Forbes. It differs from the N. macula in having the spire less produced, 

 the body whorl much more ventricose, and the longitudinal ribs fewer ; it 

 appears intermediate between the N. macula and N. ambigua. 



|| The only specimen of this shell has unfortunately been lost. From a 

 sketch from memory sent to me by Mr Strickland, it appears to have been 

 nearly an inch long. I suspect that both Testacea and Zoophytes, notwith- 

 standing their limited powers of locomotion, are occasionally drifted from 

 distant seas to our shores, probably entangled in floating substances. The 

 Rev. Mr Landsborough has found, on the shores in his parish, Bulla striata 

 and Nerita peleronta, and fragments of Transatlantic coral, both on the 

 present sea-beach and in the ancient deposit ; and he has in his collection 

 a Littorina Peruviana, found by Dr Curdie on the Island of Gigha, and 

 Oliva nana, a West Indian species, found by Miss H. Carmichael on the 

 shore at Cumbra. The Oliva mentioned by Mr Murchison may therefore 

 have been a straggler, and not a native of the British Seas.
