ex INFERIOR OOLITE AMMONITES. 



Remarks— A tendency to plump up the body-chamber is seen in figs. 7, 8 r 

 Plate XVI. 



Corrections. — Plate XVI, fig. 7, umbilicus is shown too concentric; the penulti- 

 mate whorl should be broader. Fig. 8, carina at top is too prominent. 



Localities and Strata. — Dorset: Bradford Abbas, Fossil Bed; Stoke Knap,. 

 Building Stone, layer 3. 



Date of Existence. — Discitx hemera. 



3. Rkyxkski.i.a [no ps, S. Buchnan. Suppl., Plate XXI, figs. 37 — 39. 



Description. — Subangustumbilicate ; parvicostate to obscuricostate. 

 Distinction. — From Beynesella /nodes, smaller ornamentation. 

 Localities and Strata. — Dorset : Stoke Knap, near Broad Windsor, Building- 

 Stone ; Bradford Abbas, Fossil Bed. 



Date of Existence. — Discitse hemera, presumably. 



4. Rkvxkski.i.a ? rodburgensis, 8. Buckman. Suppl., Plate XVII, figs. 1 — 3. 



Description. — Subangustumbilicate; costate to subcostate ; many connaticostos, 

 particularly in the umbilicus ; distinct carina, declining on body-chamber. 



Distinction. — From 11. juncta ; stouter whorls, a smaller umbilicus, more con- 

 conspicuous, rather more distant, costse. 



Remarks. — In ornament the species has much the appearance of Beynesella, but 

 the build of the whorls indicates a different stock. 



Localities and Strata. — Gloucestershire: Rodborough Hill, near Stroud, Lower 

 Trigonia-grit, 1 foot 10 inches from base. Dorset: Bradford Abbas, Fossil Bed. 



Date of Existence. — Discitse hemera. 



5. Reynesella? i.ixkata, 8. Buck man. Suppl., Plate XVII, figs. 25 — 27. 



Description. — Parvicostate, the costse mostly bifurcate; gradumbilicate ; peri- 

 phery subtabulate, distincticarinate. 



Remarks. — Like B. inops, but the radial line is more curved and more projected 

 peripherally. The costge are less distinct in the umbilicus, but they remain more 

 persistent. The umbilicus is slightly less concentric; the periphery is less 

 distinctly tabulate, the angle between lateral area and periphery being less- 

 definite. 



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



Pair of Hrislriirr. — l>iscit,r hemera, presumably.
