Hello,
I have these two bivalves from Martinique isl. (West Indies). Any help to identify them would be welcome. This one looks to be a Tellinidae, it measures 16mm.  That one is 21.5 mm  Ta. Pierre. |

The first one looks like Scissula similis (J. Sowerby, 1806)
The second may well be Semele proficua (Pulteney, 1799) |

The second ID is probably wrong. Still working on it with Harry. Probably a Tellin.
Update: Harry has ascertained that the second shell is most probably Macoma pseudomera Dall and Simpson, 1901. Harry commented: "It is rare in collections, and I have only collected it in Puerto Rico myself. Although nondescript to a degree, it has a unique shape, pretty unusual pallial sinus, and a subtle radial sculpture not seen in many otherwise similar species. Semelids have an internal ligament; tellinines have lateral teeth, and the most similar species, Heterodonax bimaculatus is more colorful, has laterals, and is a little more produced posteriorly." Much appreciation to Harry for this effort and his continuing support. |
