When I was on my honeymoon (field trip) in Jamaica in 1972, I collected several specimens of a freshwater nerite in the Rio Grande, near Port Antonio, on the east coast of the island. These were collected several miles upstream during a rafting trip. I do remember that they were not small and black.
I can't give any more details as I am now in Korea and my collection is back home in Newfoundland, Canada. However, I did assign a tentative name to them, from some old literature, but I can't remember what it was. It's been several years since I looked at my Jamaican shells.
Hope this is of some help to you.
Malacologically yours,
Ron
