This article is about the Gasteropoda species collected at Reina beach in the Montijo district, province of Veraguas, deposited in the National Reference Collection of the Museum of Malacology of the University of Panama (MUMAUP). Mariato, is located at 7 ° 37'16.99 "LN and 80 ° 59'42.79" LO; The beach has an extensive rocky coastline of rocks and rocks, few sandy sections with mud-sand patches, the water is murky, and is filled with a lot of sediment. The specimens were collected manually from six biotopes (rocks, stones, mud-sand, sand, dead coral and estuary); With a total of 26 324 individuals, 133 species, 82 genera, 42 families, 38 superfamilies’ and eight orders; 99 species were in the rocks, 38 in the stones and 15 in both places of the rocky coast; The rocks were the biotope where most species were collected, none was found in more than two biotopes. Economically important specimens such as Malea ringens (Swainson, 1822), Hexaplex radix (Gmelin, 1791), H. regius (Swainson 1821) and Vasula melons (Duclos 1832) were collected.
