XVI.—WNotes on the Mollusca in the Great International 
Fisheries Exhibition, London, 1883, with the Description of 
a new Species of Pleurotoma. By J. GwyN JEFFREYS, 
DRS: 
THE interest taken by the public in this great world’s show 
continues unabated. But it does not seem to have attracted 
the attention of conchologists; although the contrary might 
have been expected, seeing that many of our rarest shells have 
been procured from the stomachs of fishes and even been 
caught by the bait intended for the latter. 
Apart from the economic or food-supplying object of the 
Exhibition, there is not much of science or natural history in 
the department of Mollusca. Oysters, of course, play a con- 
siderable and aristocratic part in it, and are amply displayed. 
Not so with mussels, cockles, whelks, periwinkles, and other 
“small deer,” which are so relished by the poorer classes in 
the dog days. 
The Mollusca are well known to constitute, together with 
Crustacea, Annelids, and various other invertebrate animals, 
the principal food of most fishes. I have myself seen between 
thirty and forty specimens of the common whelk (Buccenum 
undatum) taken from the stomach of a single cod. Orsted 
says, in his interesting treatise ‘ De regionibus marinis,’ 
* Type Felis planiceps, Vig. Horsf. Char. Second (first) superior pre- 
molar two-rooted ; orbit closed behind; pupil round. 
+ Mr. Wortman has called my attention to a character of this genus 
which confirms its separation from Felis, as I proposed in 1879. The 
maxilloturbinal bone is less complex in the genus Uncia than in Felis, 
consistently with a less nocturnal habit and less necessity for acute 
smell.
