126 MISS M. E. J. CHANDLER ON THE [vol. lxxix, 



or nearly marginal to the apex, where it passes directly into the 

 seed-cavity; digitate cells of the interior of the keel very contorted. 



Dimensions. — Length = 6*5 mm.; breadth = 4 mm. (largest 

 example). Length=3 - 25 mm. ; breadth=2 - 25 mm. (smallest 

 example). Length=4 - 5 mm. ; breadth=3 - 25 to 225 mm. (average 

 specimen). 



Horizon. — Upper Eocene, Lower Headon Beds. 



Localities. — Hordle (Hampshire) ; Colwell Bay (Isle of 

 Wight). The species is distinguished by its small size, its flatness, 

 its great breadth, largely due to the broad flat keel, its marginal 

 raphe, and its highly contorted cells on the keel. In worn 

 examples the marginal raphe is frequently in part eroded : it then 

 appears to enter halfway up the dorsal edge of the seed. Many of 

 the Colwell Bay specimens appear to have suffered from the 

 attack of a fungus, as they are frequently distorted, and bear 

 irregular warts or spines ; often the distorted specimens are 

 marked by spherical brown pustules, near which they tend to 

 crack. 



The Hordle specimens were particularly abundant in Beds 10 

 and 31 of E. B. Tawney & H. Keeping. 1

'\? F. tlialictroides Brongniart (Bristow-Strahan-Reid 31). 



Seed oblong or suboval. hooked at the base, flattened; keel 

 moderately broad to narrow, not continued round the base, merging 

 gradually into the collar. Collar large, prominent, rounded, 

 smooth ; testa thick, woody, with irregular longitudinal tubercles 

 often coalescing to form longitudinal ridges, not continued on to 

 the collar, frequently present, although less well-defined on the 

 keel; pitting of surface fairly coarse; micropyle basal or sub- 

 basal, slightly oblique; hilum dorsal, near the base; raphe marginal 

 from the hilum to the middle of the dorsal side, thereafter diagonal 

 to the apex, where it enters the seed-cavity. The curvature of the 

 diagonal portion is such that the width of testa external to the 

 raphe is usually less than the width of testa on its inner side; 

 digitate cells of the interior of the keel tortuous and convolute. 



Dimensions. — Length = 8 - 5 mm. ; breadth=3 - 5 mm. (largest). 

 Length = 5*5 mm.; breadth = 2 - 5 mm. (smallest). Length = 

 7 mm. ; breadth =3*5 mm. (average specimen). 



Horizon. — Middle Oligocene, Bembridge Marls. 



Localities. — Grurnet (Gurnard) Bay, Hamstead, Thorness 

 Bay, and ? Foreland Point (Isle of Wight). The specimens were 

 abundant in clays and marls, and also in solid blocks of pyrites in 

 the marls.
