Harry,
If someone is working on refining the geographic distribution of M. ofytatus, here are the coordinates for the three lots we dredged:
Lot 27967: 29º43.08'N, 85º53.16'W- Dredged in 39 to 38.7 m in rubble
Lot 31232: 24º48.929'N, 83º40.609'W to 24º49.142'N, 83º40.587'W- Dreged in 65 m, in rubble and crushed shells
Lot 31272: 24º32.763'N, 83º22.875'W to 24º32.974'N, 83º23.285'W- Dredged in 68 m in rubble
Best,
Emilio

Thanks, Emilio.
Submersion at higher latitudes seems to be operative here.
The "off Tampa," "off Egmont Key," and "1962" sound suspiciously like
Jim Moore, who worked in depths like you did.
