SUPPLEMENT.— (EDANIA. cvii 



3. Daeellina (?) docilis, 8. Buckman. SuppL, Plate XXII, figs. 4 — 6." 



Description. — Subangustumbilicate, parvi- and subspissicostate, connaticostatc, 

 costas declining. 



Remarks. — Radial line like that of Darellina, but less distinctly biarcuate; 

 costge more numerous and more distinctly connate ; whorls less compressed. More 

 numerously costate and more distinctly carinate than Reynesia furcillata. 



Locality and Stratum. — Dorset: Bradford Abbas, Fossil Bed. 



Date of Existence. — Discitse hemera. 



XLI. Genus — Daeellella, 8. Burl-man. 



(Type : Barellella redicostata, sp. n.) 



Definition. — Like Darellina, but the radial line almost coincides with the guide 

 line, the costa? being noticeably straight. (Radial line, fig. 68, p. clxv.) 



Daeellella eecticostata, S. Burl-man. SuppL, Plate XVII, figs. 10 — 12. 



Remarks. — This is one of the most distinct species of the Bradford Abbas Fossil 

 Bed ; its straight ribs, with so little peripheral projection, are an unusual feature 

 among the Hildoceratidae. Twenty years ago I recognised this species as new, but 

 I have not figured it before on account of doubts as to its affinities. It is a rare 

 form, not simply scarce because easily confounded as others may be. Only a few 

 specimens much smaller than the figured example have rewarded diligent search. 



Locality and Stratum. — Dorset : Bradford Abbas, Fossil Bed, upper part. 



Date of Existence. — Discitse hemera. 



Distincticarinate. 



In the following genera the carina stands out definitely from the tabulate 

 periphery. Gerontic decline may affect its prominence somewhat, as in (Edania. 



Falcate to biarcuate. 



Body-chamber has a tendency to thicken. 



Angustumbilicate. 



XLII. Genus — (Edania, 1 S. Buckman. 



(Type: (Edania falcigera, sp. n.) 



Definition.— Platysubleptogyral, angustumbilicate; laterally anguHradiate ; 

 peripherally anguliradiate, tabulate, distincticarinate. (Radial line, fig. 69, p. clxv.)
