2. Paludestrina ulv^. Petm. 



Locality. Cor. Crag, Gedgrave. Recent, Britain. 



A few specimens of this very common estuary species were found by myself on the 

 upper part of the Coralline Crag, along with some Helices, Cyrence, and the usual common 

 marine shells of that formation. The spot whence they were obtained is near the 

 surface, and it may possibly have been some disturbed and redeposited material of a 

 more modern period. My specimens are strongly tinged with their natural colour, 

 and have the aspect of recent shells. 



3. Paludestrina (?) terebellata. Nyst. Tab. XII, fig. 7. 



Melaxia terebellata. Nyst. Coq. foss. de Belg. p. 413, pi. 38, fig. 12, 1844. 



P. Testa turritd, elonyato-conoided, crassd, lavigatd (?) ; anfractibus septem vel octo, 

 planulatis ; ultimo anfractu, obtuse angulato ; aperturd ovatd utrinque subacutd; labia reflexo, 

 umbilico tecto. 



Shell turreted, of an elongato-conical shape, thick and strong, with seven or eight 

 rather flat and smooth (?) volutions ; last whorl subangulated at the base ; aperture 

 shghtly acuminated above and below ; left lip a little reflected, covering the umbilicus. 



Axis, I of an inch. 



Locality. Red Crag, Sutton and Walton Naze. 



This is not a very abundant species, and is always in a more or less mutilated and 

 altered condition ; aU my specimens have been much rubbed and decorticated, and the 

 lines of growth are not clearly distinguishable. Its appropriation to the present genus 

 is a doubtful one. 



4. Paludestrina (?) pendula. S. Wood. Tab. XII, fig. 6. 



EuLiJJA PENDULA. S. JVood. Catalogue 1842. 



P. Testa turritd, subidatd, elongatd, Icevigatd ; anfractibus 8 — 9, convexiusculis ; 

 aperturd ovatd ; labio subrejtexo. 



Shell turreted, tapering, elongated, and smooth, with eight or nine slightly convex 

 volutions ; aperture ovate, acuminated at the upper part ; left lip slightly reflected. 



Axis, I of an inch. 



Locality. Red Crag, Walton Naze. 



Although not a very rare shell, my specimens are all much rubbed or decorticated; 

 those which ^re most perfect have about eight slightly convex volutions, with an aper- 

 ture resembling shells of this genus. This may be also considered doubtfully appro- 

 priated to this genus. It is an elegantly-fonned shell, somewhat resembling an 

 elongated ear-drop.
