oL2, G. W. LAMPLUGH ON SHELLY PATCHES IN THE 
obtusus in being much shorter and proportionally broader, deeply 
constricted in the upper part, and having a narrower mouth. 
5, BULLA CREBRISTRIATA *, Jeffreys. Pl. XV. fig. 6.. 
Shell cylindrically oval, thin, semitransparent and glossy : sculpture, 
extremely numerous, close-set and fine spiral strive, besides irregular 
lines of growth; the spiral strie are wavy and interrupted by the 
lines of growth, but are not punctured: colour yellowish-brown : 
spire sunken and quite concealed ; crown excavated and encircled 
by a sharp rim: mouth long and flexuous, narrower on the upper 
part and expanding below the pillar: outer lip flexuous, slightly 
projecting above the crown: iner lip rather thick; behind it at 
the base of the pillar is a small umbilical groove. Length 02 in. 
Breadth 0°15 in. 
Two specimens, but neither of them is quite perfect.

Hameri, Ascanius. Verruca Stromii, Miller. 
Fragments of Balani were plentiful in the beds out of which the 
above have been identified.

Pisczs. 
By E. T. Newron, Esq., F.G.S. 
In Mr. Headley’s collection were many teeth and other re- 
mains of fish. These were nearly all obtained from the sandy 
patches, and were in many cases much water-worn and rounded, 
being sometimes reduced to mere pebbles. Some, however, were 
quite unworn, and in an excellent state of preservation. 
Nearly the whole of the remains of Fishes from Bridlington seem 
to be either Norwich-Crag, Red-Crag, or London-Clay forms. And 
seeing that so many of the Crag Vertebrata have been originally de- 
rived from the London Clay, itis quite possible thatall the Bridlington 
Fishes have been derived directly from the Crags. I should doubt 
whether any of them were contemporaneous with the Bridlington 
deposits, and the mineral condition and polished surface of the 
specimens are characteristic of Crag fossils. 
This would seem to point to the destruction of older Tertiary beds 
during the formation of the gravelly sand containing the arctic 
fauna. 
Dr. 8. P. Woodward, in a note to his list of shells in the ‘ Geological 
Magazine,’ vol. i. p. 49, 1864, mentions the occurrence of Plataa 
Woodwardi, sharks’ teeth, and an otolith resembling those of the 
* Closely striated.
