Well, here are some pictures from Lamarck's collection in Paris MNH
http://www.wonderphotos.com/shellphotos/anadara_brasiliana_2.jpg
the Holotype shape looks like the specimen from Texas, but the texture is
smoother like Brazilian shells.
Some shells from Venezuela also have rough texture, but not as much as
Texan specimens - and they are taller like Brazilian shells;
Maybe we will only know if someone makes a comparative anatomy study.
