PLATE XXXIII. 
CONULARIA TJNDULATA. 
Page 208. 
Figs. 1, 2. Two views of a slightly compressed cast of an imperfect specimen, showing the expansion, and the 
general characters of the species. 
Figs. 3, 4. The opposite sides of a larger cast, somewhat compressed, showing a more gradual tapering 
form, with the deeply concave septum truncating the apex. 
Fig. 5. From a gutta-percha impression in the natural lhold, the specimen showing a rapidly tapering shell, 
as in figures 1 and 2, with crowded striae at the lower extremity. The surface is marked by the 
imprints of several Discika which have been attached to the surface. It is possible that further 
examination, with a larger number of specimens, may prove the form shown in figures 1, 2 and 
5 distinct from that of figures 3 and 4. 
Fig. 7. A diagram giving the form of a transverse section of the. specimen figures 1 and 2. 
CONULARIA CONTINENS.

Fig. 6. An enlargement of the surface from a well-preserved specimen. 
CONULARIA CREBRISTRIATA. 
Page 210. 
Fig. 8. A fragment in shale, showing a very gradual expansion of the cone, and very fine crowded trans¬ 
verse striae. 
Fig. 9. Enlargement of the surface, showing the transverse striae apparently destitute of nodes. This 
appearance may be due to partial exfoliation of the shell.
