I need to make a correction to my November 8th post. The snail description was made by Samuel J. Parker–Not Helen’s future Father-in-Law, but her future Brother-in-Law. Samuel J. Parker became a physican and to my knowledge never published anything about snails or nature again.
So do I still think Helen Fitch wrote the description for the undescribed species of snail? Yes, I think it came from her and not from him.
