• The paper does not give any specific information on the lithology or the geologic setting of the fossils. The time frame selected is "Holocene" but it appears that the author is describing recent species as he gives no indication as to how old the specimens are. Also, some of the locations for this paper are lumped together because of the very general ways in which the locations are described. For example, "...not uncommon on the Florida Coast." Where this is done I will include the page number that can be referenced in regards to the species under the notes section of the taxonomic list.
• In the Smithsonian Museum, there are specimens from Florida, and others collected at Aspinwall by Mr. Rowell.
