Iiv INFERIOR OOLITE AMMONITES. 



3. Cosmogyeia sp. Suppl., Plate XIV, figs. 11, 12. 



The small specimen figured is not the young of any species which has been 

 described. 



The radial line seems to indicate its position in this genus. 

 Locality and Stratum. — Dorset: Chideock Hill, in the " Wild Bed." 

 Date of Existence. — Murchisonse heniera. 



In the following species the character of the suture-line agrees with that of 

 this genus ; and so do the proportions in the case of the first. But the radial 

 line differs, — there is more lateral curvature.

figs. 26—28.

 of Mr. T. C. Maggs, F.G.S., and one from my father's Collection, from the 

 Bhynchonella ringens bed ; Louse Hill, near Halfway House. 



Date of Existence. — Bradfordensis hemera. 



5. Cosmogyria? cikrata, S. Buckman. Suppl., Plate X, figs. 32 — 34.

 nella ringens bed.
