the bed here so marked may not be an upper member of the middle 



division. 

 In the above sections the principal masses only of drift are shown. In No. 2 

 there is a drift in the valley between Richborough and Woodnesborough Hill. In 

 No, 3, besides the drift marked on the top of the cliffs, there are some detached 

 masses on the lower cUffs between d and the Reculvers. In No. 4, patches of a 

 mixed drift occur occasionally in places on the slope of the hill above b, and a thick 

 mass of brick-earth drift is worked at the base of it. The same, with gravel and 

 mammalian remains, is largely developed at the foot of the chalk hill to the left 

 of the section. 



Description of some Fossil SHELLs/rom the Lower Thanet 

 Sands. By J. Morris, F.G.S. 



Sanguinolaria Edvardsii, n. sp. Plate XVI. fig. 1. 



Testa elliptica, compressa, insequilaterali, transversim striata ; antice attenuata, 

 postice rotundato-truncata ; umbonibus prominulis. 



An ovate-lanceolate, inequilateral shell, somewhat compressed, 

 marked by numerous fine, sharp, raised striae, which are more pro- 

 minent towards the lateral margins ; anterior extremity attenuated, 

 posterior extremity rotundato-truncate. Width rather more than 

 twice the length. 



Named in compliment to Mr. Frederick Edwards, of Hampstead, 

 to whom we are indebted for much information on Tertiary Palaeon- 

 tology. 



Heme Bay. Specimen figured, from Mr. Edwards's Collection. 



Glycimeris Rutupiensis, n. sp. Plate XVI. fig. 2. 



Testa transversa, elongata, subsequilaterali, subconvexa, transversim striata ; lateri- 

 bus rotundatis ; margine medio subdepresso, margine cardinali calloso ; umbo- 

 nibus obsoletis. 



A transversely elongated, nearly equilateral, and somewhat convex 

 shell, with rounded extremities, the dorsal and ventral margins 

 parallel ; both valves having a slight depression in the middle, which 

 extends to the ventral margin ; lines of growth numerous, sharp. 

 Width 2\ times the length. 



This shell is distinguished from G. angusta, Nyst, by its more 

 equilateral form, and by the dorsal margin being less angular, and 

 the posterior extremity more rounded. 



The species of this genus are very rare in a fossil state, having been 

 only found at present in the Tertiary strata. The one above described 

 is the most ancient known form, the other belongs to the Crag of 

 Belgium and England.

Panop^ea granulata, n. sp. Plate XVI. fig. 3. 



Testa ovato-oblonga, transversa, insequilaterali, granulata, transversim irregulariter 

 striata vel undulata ; margine medio subcompresso ; lateribus rotundatis ; um- 

 bonibus minimis, incurvis. 



An ovate, elongated shell, with rounded extremities ; somewhat 

 cylindrical ; the middle of both valves depressed near the ventral
