civ INFERIOR OOLITE AMMONITES. 



Description. — Subangustumbilicate, subcostate, striicostate to smooth. 



Distinction. — From R. intermedia, a larger umbilicus, rather less costate ; more 

 persistent costoe on the whorl. 



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

 Building Stone. 



Date of Existence. — Discitse hemera, presumably.

 1902. Eeynesia ccela, Emend. Amni. Nom., p. 5. 



Description . — Angustumbilicate ; subcostate. 



Distinction. — From B. laxa, a smaller umbilicus, also the costee are rather more 

 distinct, especially on the inner part of the whorl. 



Remarks. — A possible angustumbilicate development of B. laxa ; but the 

 association may not be justified. 



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

 Frith Quarry, near Stroud, Lower Trigonia-grit. 



Date of Existence. — Discitae hemera.

 1902. Eeynesia lepida, Emend. Amm. Nom., p. 5. 



Description . — Subangustumbilicate, levigate. 

 Distinction. — From B. laxa, the greater smoothness. 

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

 Date of Existence.— Discitse hemera, presumably. 



6. Reynesia puecillata, S. Burl-man. Suppl., Plate XXII, figs. 1 — 3. 



Description. — Platy-subleptogyral ; subangustumbilicate ; connaticostate, costge 

 declining in strength. 



Remarks. — The umbilication and ornament suggest that this species represents 

 the costate, more uinbilicate, relative of B. benigna. Against this are the small 

 carina and the less flexed radial-line. 



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



Date of Existence. — Discitse hemera,
