Shell turreted, costated, and spirally striated, ribs numerous, with close-set striz ; upper volutions

Length, + inch. 
Locality. Cor. Crag, Sutton. Recent, Britain. 
A single specimen, but not in good condition, is in my cabinet, and appears to correspond with what 
the British conchologists have confidently proposed as a distinct species. I believe the Crag fossil to be 
identical with the living shell. 
I have withheld a notice of this, as well as a few other imperfect specimens from the Crag, up to the 
present time, in the hope of being able to procure-something better to represent than what I am now only 
able to give. 
Nassa Monensis, Forbes, MS. 
Nassa Monensts. Strickland. Proc. Geol. Soc., vol. iv, p. 8. 
In the first volume of my Monograph, p. 31, t. 3, fig. 5, a Red Crag shell was considered to have 
belonged to the above species, and it was inserted as such upon the authority of the late Professor E. 
Forbes. Mr. Smith has recently sent me a MS. note, accompanied with a sketch, by the original 
discoverer, of what is there called N. Monensis. “‘ Nassa differing from N. macula in having the spire less 
produced, the body whorl much more ventricose, and the longitudinal ribs fewer. It appears intermediate 
between N. macula and N. ambigua.’’ Forbes. The figure presents some considerable differences from the 
Crag shell, and I regret my inability to obtain a sight of the Manx specimen; they must, therefore, remain 
united for the present. 
Nassa Putocena. Strickland. Proc. Geol. Soc., vol. iv, p. 9. 
Locality. Isle of Man. 
This shell I have been unable to obtain a sight of. 
Nassa reticulata is enumerated in Mr. Smith’s ‘List of the Clyde Fossils,’ ‘Proc. Geol. Soc.,’ vol. iv, p. 9. 
“*BuccinuM cruiatum. Fabricius. 
“Syn. (a variety.) Buccinum Humphreysianum, Bennett. Possibly, Buc. fusiforme, of Broderip, may 
be an extreme form of this species. 
“Locality. Fossil, North of England and Scotland. 
Tiving, very rare in the British Seas, common in Arctic Seas and on the Banks of 
Newfoundland.” —Forbes, ‘Mem. Geol. Surv.,’ vol. i, p. 427. 
This is another recorded British Tertiary fossil that I have been unable to obtain a sight of.
