INFERIOR OOLITE AMMONITES. 



3. Beaunsina cornigera, 8. Buchman. Suppl., Plate XX, figs. 4 — 6. 



Description. — Gradumbilicate, costate. 



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

 part. 



Date of Existence. — Discitse, hemera, presumably. 



In species 4 to 7 connate costse are more in evidence than in species 2 and 3. 

 Braunsina elegantnla is stouter whorled and more distinctly costate than B. corni- 

 gera ; its costse are also more definitely V-script. 



4. Braunsina elegantula, 8. Buchman. Suppl., Plate XIX, figs. 1 — 3. 



Description. — Gradumbilicate, connaticostate. 



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



Date of Existence. — Discitse hemera. 



5. Braunsina projecta, S. Buchnan. Suppl., Plate XX, figs. 7 — 9. 



Description. — Subconcavumbilicate, subparvicostate. 



Remarks. — The umbilicus shows ornament of the connaticostate character. 



Distinction. — From B. elegantula, smaller umbilicus, less pronounced ornament. 



Localities and Strata. — Somerset : " Dundry Hill, West End," from E. Wilson, 

 from upper part grey Limestone and Marl Beds, about Nos. 10 to 13, ' Q. J. Gr. S.,' 

 vol. lii, p. G77. Gloucestershire : Cheltenham district, evidently from the Lower 

 Trigonia-gvit. It is from my father's collection, and is marked " A. canaliculatus, 

 Bronn," which, however, is entered in ' Greol. Cheltenham,' ed. 2, p. 89, as from 

 Middle Lias, Dumbleton : that is certainly a mistake. 



Date of Existence. — Discitse hemera. 



6. Braunsina eastigata, 8. Buchnan. Suppl., Plate XX, figs. 1 — 3. 



Description. — Subconcavumbilicate, parvicostate.
