1-10. — C7/prma BernensiSf heym. ; C. MarcousanajljOY. ; C. DesJiai/esiana,'Lor.', C. Carteroni^ 

 d^Orb. ; C. Valangiensis, Auhenonensis^ fusi/ormis, and Orhensis of Pict. and Camp.; C. Ahhatice^ 

 d^Arch. j C. securiformis, Sharpe; — except the last named species, which is to all appearance a 

 true Cyprina, the others are only known from more or less imperfect casts which do not admit of a 

 correct generic determination. 



11. — C. Sammri) P. and Renev.^ is probably a Cyprina. 



1^. — C. angulata, Sow. Pietet and Campiche (loc. cit., p. 221^ &c.J devote a good deal of 

 attention to this interesting species which^ they say^ they had compared with specimens from 

 Nievre and Sonne, &c.; they identify it with Leymerie^s and ^^OxV\^\ij'^ Ervyensis. I am 

 sorry that I have no good specimens from either of the localities to compare, but there is certainly 

 a discrepancy in the figures, which is worth noticing; for unless it had been explained, it is 

 almost impossible to arrive at the proper generic determination of the shell, though the specific one 

 may be quite correct. Sowerby^s original figure (Min. Conch., pi. 65,) shows in the left valve 

 three cardinal, one lunular (or perhaps anterior lateral) and one posterior lateral tooth ; the author's 

 description does not give an explanation of this, and it is almost certain that there must be some kind 

 of mistake in the figure, for it does not correspond with any known genus of the VENERACEA. 

 D'Orbigny's figure of a part of the hinge of the right valve is also not suflacient to clear up 

 the matter ; there we have only two divergent cardinal teeth ; the lower anterior must be wanting 

 if the figure be intended to represent a Cyprina, 



13.--(7. Tostrata, Sow. The original figure of the left valve evidently represents a form of 

 Veniella, namely, the sub-genus Venilicardia, 



14-15. — C. inornata^ d'Orb., and C, Rliodani, P. and Eoux. 



16.— a cordiformis, d'Orb. The figure of the hinge of the left valve is not quite complete, y^li^ti^^J, r 

 but it clearly seems to indicate a species of Veniella, perhaps belonging to the sub-genus Anisocardia, ]c<^-n^<^^ J^^ 



17.— a regularised' Ovh.; the figure of the hinge of the left valve seems imperfect, unless 

 it represents a species of Cardiodonta, and even with this the position of the hinge-teeth does not 

 quite agree. 



18.— C. quadrata, d'Orb. Judging from d'Orbigny's figure it may be a form of Veniella, 

 but with enormously strong cardinal, and very small posterior lateral teeth. 



Geinitz (Quadersandstgeb., p. 156,) identifies with it his Isocardia cretacea, a view which is not 

 supported by the description and figure given of the last named species. The same author also 

 quotes Trigonia parvula of Eeuss, being probably identical with C. quadrata ; this seems still less 

 probable; but, of course, it is very difficult to judge from figures of very imperfect specimens. 

 We have several specimens of Geinitz' /. cretacea in our collection, but they are perfectly insuffi- 

 cient to clear up the doubtful points. 



19.— C. crassicornis, Ag., sp. Judging from the inflated form and apparently thin texture of the 

 shell I think this species probably an Anisocardia, 



20. — C, cuneata^ Sow. This is a typical Anisocardia (Yeniella). Sowerby gives the figure of 

 the left valve, and I have examined the perfect hinge of the right valve in our own collection. 



21.— (7. Fergusoni, Salt. Eeference is made to the presence of a lateral tooth, but the 

 cardinals are not pointed out. 



22.— C. globosa, Sharpe. Gabb (Proc. Am. Phil. Soc, &c., June 1861, vol. viii, p. 175,) 

 substitutes for this name C. Sharpeana, the name C. glolosa having been already formerly applied 

 by d'Orbigny to Romer's Jurassic Cardium glohosum, which is identified with Goldfuss' 

 Venus tmuistria. It is difficult to say which name will stand. In Romer's figure of a cast 

 the number of the ribs is evidently exaggerated, it amounts to about half a dozen. Goldf uss' 

 figure of a left valve, if correct, represents an Anisocardia; thus Sharpens name may after all 

 not require to be changed, but unfortunately the figure and description which he gives of his 

 species do not allow of a generic determination.
