Description of some new Fossil Species collected hy John Bkown, 

 Esq., E.G.S., at Geove Eerry, Kent. By G. B. Sowerby, Esq., 

 E.L.S. 



Balanfs Chisletianijs, G. B. Sowerby. PI. Y. fig. 7. 



B. subcylindricus, laevigatus, orificio dentato, mediocri ; parietibus leviter fas- 

 ciatis; radiis angustis; scuto Isevigato crista articulari elongata valide reflexa; 

 tergo obtuso, calcari acuminato elongate. 



The slope of the radii gives to the orifice a dentated character 

 which brings our species near to B. concavus ; but the scutal valves 

 of the operculum are without longitudinal striae, and their articular 

 ridge is long. Also the spur of the terga is oblique, produced, and 

 pointed. 



Astarte elevata, G. B. Sowerby. PI. V. fig. 6. 



A. testa trigona, alta, postice truncata subangulata, ad marginem ventralem 

 Iseyi, medio leviter liris undulata ; apice elevato hris rotundis crebris rugato. 



This shell differs from A. rugata of the * Mineral Conchology,' and 

 from A. Omalii, Lajonk. (N'yst), in being much more elevated and tri- 

 gonal. The ridges, which are strong and numerous at the apex or 

 in the young state, become faint towards the centre until they disap- 

 pear near the ventral margin. 



Pyrula nodflifera, G. B. Sowerby. PL V. fig. 2. 



P. testa oblonga, spiraliter striata, ad angulum anfractumn nodulis obtusis coro- 

 nata, supra medium nodulis ineonspicuis cincta ; spira brevi. 



A shell so simple in form as a Pyrula can be safely described even 

 from the fragmentary specimen figured, although the only characters 

 are that it is spirally striated and has one row of obtuse nodules on 

 the angle of the last whorl, and another row of very indistinct ones 

 above the centre of the same whorl. 



Bfccinum concinnum, G. B. Sowerby. PL Y. fig. 1. 



B. testa acuminata, spiraliter liris rotundis cincta ; anfractibus rotvmdis ; aper- 

 tura subquadrata ; columella umbilicata ; labio externo antice paululum pro- 

 ducto. 



A neatly-formed, acuminated shell with rounded, spiral ridges 

 upon rounded whorls. The aperture is rather square, with a narrow 

 umbilical opening behind the columella, and (judging from the lines 

 of growth) a slight forward curve in the outer lip.
