Hi Fabio,

Yes we consider them the same.  See Harry Lee's book Marine Shells of NE
Florida.  He notes that E.C. Rios, 1994. Seashells of Brasil 2a edicao.
Fundacao Cidade do Rio Grande, Rio Grande do Sul, Brasil, 99. 1-368, placed
C. floridana. in synonymity to C. sertulariarum, considering the Florida and
Brasilian shells the same.

Interesting to note that Anachis (or Costoanachis) sertulariarum also occur
down here in south Brazil.
I wonder if they are indeed the same species, or they are in fact two or
more similar species.

marlo asked:

Abbott reports C. sertulariarum from "North Carolina to Florida and Texas."
Radwin limits it in Florida to the east coast as far south as Dade County.
I've never found this shell in the Keys or west Florida.  I'd like to hear
from those with first-hand collecting records of C. sertulariarum from
anywhere in Florida.
