 Other species from this station not originally reported in above list are:

Parastarte triquetra Conrad.
Donax variabilis Say.
Gemma purpurea H. C. Lea.
 Geologic horizon given with the original report: "Probably Pliocene."
 Geologic horizon believed to be in this report: Upper Pliocene or lowest Pleistocene.
 The two species, Donax variabilis and Gemma purpurea, as noted, were not listed in the original report. The two species appear to be exclusively post-Pliocene. If they came from the same stratum as the other listed species, the age would indicate post-Pliocene rather than Pliocene.
