INFERIOR OOLITE AMMONITES. 



III. REVISION OF, AND ADDITIONS TO, VARIOUS FAMILIES. 

 Family— AMALTHEID^E . 



Sub-family — Sonninisle. 

 Germs — Zurcheria, Douville. 

 Zurcheria ruGNAX (Vacek). Suppl., Fig. 188 in text. 



1892. Zurcheria pugnax, Tins Monogr., p. 298. 



1895. — pugnax, Brasil, Ceph. Nouv. ; Bull. Soc. Geol. Normandie, 



vol. xvi, PI. ii, figs. 4, 5. 

 1902. — pugnax, 8. Buclcm., Emend. Arum. Nom., p. 7. 



This was noticed as a foreign species at p. 298. It can now be recorded as 

 British. A specimen in beautiful preservation, 53 mm. in diameter, was obtained 

 by me from the workmen at Stoke Knap, Dorset, some years ago. It came evi- 

 dently from the Building Stone, and by its matrix perhaps from the lower part ; 



that would make its date Bradford en- 

 sis hemera ; but it may be later. 



This example is a whorl larger 

 than Vacek's, and shows on this 

 whorl decline of the bispinous stage 

 i — in fact, the ornament on this 

 whorl is just that of Haplopleuro- 

 ceras. The periphery, however, is 

 quite convex, shows no carina nor 

 furrows ; but the small costse pass 

 over this periphery, making lingui- 

 form figures. 





Fig. 188. — Zurcheria pugnax. 



This specimen is most interesting in its bearing on my remarks as to the 

 genealogy of Haplopleuroceras, p. 299. My thanks are clue to Mr. J. W. Tutcher 

 for the two photographs. 



Genus — Dorsetensia, 8. Buchman. 



Dorsetensia Lennteri, Brasil. Plate LII, figs. 1—3. 



1892. Dorsetensia sp., This Monogr., PI. lii, figs. 1—3, p. 304. 

 1895 — Lennieri, Brasil, Ceph. Nouv., Bull. Soc. Geol. Normandie, 



vol. xvi, PI. iii, figs. 10, 11, p. 10. 



Found in Normandy by Mr. L. Brasil.
