See Plate 38. 



Fig'. 1. An enlftpgement lo six dinmeters from a gutta-pei-cba impression of a mould of the specimen repre- 



sonted in fig. S, plate 38 

 Fijr. 2. A small specimen with extremely fine transvei-se striae, and resembling' very closely Conularia cr»- 



brUtriata. 

 Pi(f. 3. A tiansverse section of fig. 2, showing the quadrangular form, with concave sides and indented 



angles. The si)ecimen is slightly distorted by pi-essure. 

 Fig. 4. An enlargement to six dianietei-s 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 longitu<linal striiB. 



Conularia crebristriata.

 See Plate 33. 

 Fig. B. An enlargement of the sui-face of this species to six diameters from the specimen fig. 8, pi. 83, showing 

 the n(>de8 upon the ti-ansverse lidges, and the longitudinal striae. A comjiarisou with the other 

 figures, having the same degree of enlargement, will show the distinctive featui-es of the species. 



Conularia continens. 



I'agc 213. 

 See Plates 33, 34. 

 Fig. 6. An enlargement to six diaraetei-s, showing the interlocking of the transveree ridges. The nodes are 

 pre.scrved in some parts, and the longitudinal striae are shown over the entire surface, as they 

 usually appear. 



Conularia continens, var. rudis. 



Pago 215. 

 Fig. 7. A specimen, natural size, showing the short, abrupt cone, and the strong sui-face-markings. 

 Fig. 8. An enlargement of a j)ortion of llie surface of fig. 7, showing the truii8\'cr.se i-idges, with the nodes 

 preserved on some parts; while the intermediate, longitudinal striae are strongly marked. 



Conularia congreqata. 



Page 214. 



See Plate 34. 



Fig. 9. An enlargement from the specimen illusfi-ated in fig. 1, pi. 34, 8ho\ving the strong and somewhat 



iiTegular, nodo.se, transvei-se ridges, and the intermediate, longitudinal striae, which are usually 



obscure or obsolete. 

 Rg. 10. An enlargement from another portion of the surface of the same specimen, on which the transvei-se 



ridges are almost free from nodes, and the longitudinal striae are obscurely visible ; probably 



due to maceration 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 stria 



ai-e continuous and well presei'ved. 



Conularia Newberryi. 

 Fig. 12. An enlargement to two diametei-s 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 C. continens, tig. 6.
