C. ISOCARDIA. _Buc._ cordatum, sulcis imbricatis squamis fornicatis.

"Klein, 138. isocardia fragum" had been interpolated by Linnæus; hence

the name, which was not in the original. The "fossula distincti" has

replaced the earlier "validi."

C. FRAGUM. _Buc._ subcordatum subangulatum, sulcis notatis semicirculis

elevatis.

By the addition of "mala" to the erroneously cited figure of Gualtieri,

our author has virtually repudiated it. "Spinosæ" followed "Pruni;" the

fallacious "s. rubris" was not present, nor "sæpe" either; "anteriore"

stood in the place of "postico," and "postico" in that of "antico." The

descriptions of the "rima" and "anus" have been added: "recurvati" and

"fossula distincti" were amplifications.
