Parastarte triquetra Conrad, not found. Parastarte triquetra Conrad. Ensis (fragment). Ensis, fragment.
Mulinia lateralis Say, var. carbuloides Mulinia lateralis Say.

Balanus sp. Balanus sp.
 Geologic horizon given in the original report: Pliocene.
 Geologic horizon believed to be in this report: Probably Miocene, including some Pliocene.

 The presence of the species Dentalium, near D. attenuatum, Leda trochilia, and Turritella burdeni ( ?) suggest Miocene. Leda trochilia is common in the Miocene. There are in the National Museum collection, three or four specimens from the Caloosahatchee Pliocene very near Leda trochilia, but Leda ctcuta is the most common species there.
