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. attenuation, 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 acuta is the most common species there.

Geologic horizon given in original report: Probably Pliocene. 
Geologic horizon believed to be in this report: uppermost Pliocene 
or lowest Pleistocene. 
Area campyla appears to be confined to the Pliocene. The form in 
this collection is nearer to this species although not typical.
