 numbers referring to the page in the B. A. Eeport which contains the abstract. 



Keport, 215. Acmcea scutum, D'Orb. [is quite distinct from A. persona, Esch. The 

 latter, as figured by Slidd., is a very young shell, not certainly be- 

 longing to the species]. 



216. TurriteUa Eschrichtii. [=54Sj«?M_;?fos«)n, Gld., May 1849. There 

 being no month-date to Midd.'s species, the excellent name of Gld., 

 which may also be of Phil. 1848, should be retained.]

 Probably the shells intended are Chlorostoma funehrah, A. Ad., 

 and its congeners.]
