Some Range Data

Conch-L post by Harry Lee 8/1/13:

"Jacksonville Shell Club member Brian Marshall has just discovered a living colony of Nerita fulgurans on the jetty rocks of Fort Clinch, Nassau Co., FL at the mouth of the St. Marys River/GA border. This constitutes the northernmost living colony of the genus in the continental Americas.

On 23 January, 2007 Marlo wrote to Conch-L:

'Over the course of the last four weeks, numerous contributors have helped refine our knowledge of the geographical limits of distribution for the four true nerites of the western Atlantic (alphabetical order):'

'Although all four species are found in Bermuda, we have found that their ranges on continental shores show differences. Besides Bermuda, there are four geographic zones where these species find limits to their distribution: South America, the western Gulf of Mexico, west Florida, and east Florida (listed in descending order of range extent):

South America:
N. fulgurans Estado Rio Grande do Norte, Brazil (Malacolog 4.1.0)
N. tessellata Estado Piaui, Brazil (Malacolog 4.1.0)
N. versicolor Venezuela, Trinidad (Malacolog 4.1.0)
N. peloronta Venezuela, Trinidad (Malacolog 4.1.0)

Western Gulf of Mexico:
N. fulgurans Port Aransas, TX. Andrews (1971: 57)
N. versicolor South Padre Is., TX. D. Harris ! (Leslie Crnkovic, Conch-L).
N. tessellata Punta Delgada, Estado Veracruz, Mexico. (Alvarado, MS thesis; through Fabio Moretzsohn, Conch-L)
N. peloronta Montepio, Estado Veracruz, Mexico. (Alvarado, MS thesis; through Fabio Moretzsohn, Conch-L)

West Florida:
N. tessellata Longboat Key, Sarasota Co.(online museum record: FLMNH 125278; rocks on the channel side H. H. Kohr!) substantiated by Sanibel, Lee Co. (Anne Joffe, Conch-L) and museum records of varying levels of rigor.
N. fulgurans Marco, Collier Co. (Lyle Therriault, Conch-L) ID to be confirmed.
[N. peloronta Sanibel Is., Lee Co [?] (on-line museum record: Carnegie 62.18495)].
[N. versicolor: Marco, Collier Co. [?] (on-line museum record: FLMNH 9557)].
