See Plate 33. 
Fig. 1. An enlargement 16 six diameters from a gutta-percha impression of a mould of the specimen repre¬ 
sented in fig. 5, plate 33 
Fig. 2. A small specimen with extremely fine transverse strise, and resembling very closely Conularia cre- 
bristriata. 
Fig. 3. A transverse section of fig. 2, showing the quadrangular form, with concave sides and indented 
angles. The specimen is slightly distorted by pressure. 
Fig. 4. An enlargement to six diameters of the surface of the specimen fig. 2, showing the character of the 
shell surface on the right hand of the figure, and of the cast of the interior on the left, with 
the somewhat oblique longitudinal strise. 
Conularia crebristriata.

See Plate 33. 
Fig. 5, An enlargement of the surface of this species to six diameters from the specimen fig. 8, pi. 33, showing 
the nodes upon the tiCnsverse ridges, and the longitudinal strise. A comparison with the other 
figures, having the same degree of enlargement, will show the distinctive features of the species. 
Conularia continens.

See Plates 33, 34. 
Fig. 6. An enlargement to six diameters, showing the interlocking of the transverse ridges. The nodes are 
preserved in some parts, and the longitudinal strise are shown over the entire surface, as they 
usually appear. 
Conularia continens, var. rudis. 
Page 215. 
Fig. 7. A specimen, natural size, showing the short, abrupt cone, and the strong surface-markings. 
Fig. 8. An enlargement of a portion of the surface of fig. 7, showing the transverse ridges, with the nodes 
preserved on some parts; while the intermediate, longitudinal strise are strongly marked. 
Conularia congregata.

See Plate 34. 
Fig. 9. An enlargement from the specimen illustrated in fig. 1, pi. 34, showing the strong and somewhat 
irregular, nodose, transverse ridges, and the intermediate, longitudinal strise, which are usually 
obscure or obsolete. 
Fig. 10. An enlargement from another portion of the surface of the same specimen, on which the transverse 
ridges are almost free from nodes, and the longitudinal strise are obscurely visible ; probably 
due to hiaceration or exfoliation. 
Fig. 11. An enlargement from another specimen of the same species, showing the transverse ridges almost 
entirely free from, or obscurely marked by, nodes, while the intermediate, longitudinal strise 
are continuous and well preserved. 
Conularia Newberryi. 
Fig. 12. An enlargement to two diameters of the transverse ridges, showing their delicately annular 
character, and the manner of their junction along the centre of the lateral face. The figure is 
given for comparison with a similar portion of the surface of G. continens, fig. 6.
