«P. Testa parva, convexo-depressa, aequivalvi, parum inaequilatera, regulariter pectinata, radiis 10-11 superne laevigatis, basi tenue striatis, externe colore varia, interne virescente; auriculis subaequalibus, antica breviore.
(Var. α.). Testa ovali, albida, nebulis fusco-virescentibus ornata, subtus viridula, albomaculata. (Var. β.). Testa ovali, virescente, supra intentiore, subtus pallidiore aurantio variegata. Hauteur 19 à 24 mill., larg. 19 à 24 mill., épais. 5 1/2 à 7 mill. Coquille de forme arrondie dans l'âge moyen, et devenant ovalaire à l'état adulte, équivalve, presque équilatérale, peu convexe, régulièrement sillonnée en long de dix à onze rayons, lisses dans presque toute leur étendue, à l'exception de leur extrémité qui est striée; des stries au nombre d'une ou de deux courent dans l'intervalle des sillons; la teinte générale de ce peigne est verdâtre, tant en dedans qu'en dehors; la valve supérieure est ornée de nébulosités d'un vert brunâtre: sur la valve inférieure ces nébulosités sont moins nombreuses, et prennent l'aspect de taches blanchâtres: ces couleurs semblent disparaître avec l'âge; dans la var. β, ces couleurs manquent, et sont remplacées par une teinte orangée, due peut-être à une incrustation étrangère à la coquille; les auricules sont un peu inégales, et la postérieure présente toujours un peu plus d'étendue. Ce joli petit peigne , que nous décrivons d'après des exemplaires qui se trouvent dans la collection de M. Petit de la Saussaye, habite la rade de la Pointe-à-Pitre (Guadeloupe), sur des madrépores, où elle a été recueillie par M. le commandant Beau.» CONSTANT A. RÉCLUZ, 1853

Type locality.— The roads (nautical) of Pointe-à-Pitre, Guadeloupe, Lesser Antilles (Récluz, 1853:154). Other material.— Northern Dominican Republic: NMB 15834, Mao Formation on Río Gurabo 807-810 m above base of section, fragments of 1 RV (Pl. 16, Figs 4-5). Barbados: BMNH uncataloged, Highgate, from post-coral rock at elevation of 107 m (ca. 350 ft), Pleistocene; USNM, locality USGS 18382, Pine, Coral Rock at elevation of 55 m (ca. 180 ft), Pleistocene. Florida: USGS 26547 and 23593, Big B Ranch and Belle Glade, Palm Beach County, Bermont Formation, Pleistocene, 1 RV and 3 LV. Recent specimens in the Smithsonian collections from throughout the range of the species consisting of 102 lots containing ca. 350 specimens. Remarks. — The name Pecten antillarum Récluz was published on May 1, 1853 (date verified by Winckworth, 1936:154), and thus has priority over P. fucatus Reeve, 1853 (June) and P. argenteus Reeve, 1853 (August). Reeve's stated locality for P. argenteus, "China Sea," is erroneous. Extant members of the species live in shallow tropical waters ranging from Bermuda (Waller, 1973) and the central eastern coast of Florida southward to the Caribbean coast of South America. They live on terrigenous or carbonate sand or rubbly bottoms, commonly near coral reefs in association with coarse reef rubble and encrusting calcareous algae. The depth range of the extant specimens studied is from the intertidal down to ca. 70 m, although the species is most commonly found living in water < 20 m deep. Dead shells have a much broader depth range, probably due to transport down steep reef fronts (Waller, 1973, and unpublished data from Smithsonian collections). The morphology of Antillipecten antillarum is fairly constant throughout its geographic range with the exception of Cuba and Jamaica, where some specimens have higher rib counts (up to 16). Comparisons.—Among the species of Antillipecten, A. antillarum is closest to A. quemadosensis n. sp. See the following description of the new species for comparisons. Evolution.— See Antillipecten quemadosensis n. sp. Occurrence.— In the northern Dominican Republic, Antillipecten antillarum is known only from a single locality on the Río Gurabo, NMB 15834. This collecting site is in the Mao Formation, 807-810 m above the base of the section (Saunders et al., 1986: text-fi gs 4, 6), within the Globorotalia miocenica Zone and upper NN15 Zone, of early Pliocene (late Zanclean) age (Gradstein et al. 2004: fi g. 21.1). Distribution.— Outside of the Dominican Republic, fossil Antillipecten antillarum have been found in the Bermont Formation of southern Florida and the Coral Rock and younger deposits in Barbados, all of Pleistocene age, and in the Bowden shell beds of Jamaica, now regarded as late Middle Pliocene (Kohl & Robinson, 1998). I could find no specimens in the extensive Smithsonian collections from the Tamiami, Pinecrest, or Caloosahatchee formations of Florida (Upper Pliocene to early Pleistocene).» WALLER, T. R. 2011.

«Pliocene and Pleistocene of the Antillean region; living in Cuba, Guadelupe, the Bahamas, and the Florida Keys.
This species is often destitute of the nodosities, and in that condition is referable to Chlamys. The very young shell is thin and glistening, in which state it has been mistaken for the Chinese P. argenteus Reeve. Old and worn specimens have been taken for P. sulcatus Lam. Its analogue and precursor in the Antillean Oligocene is the P. anguillensis Guppy.» DALL, W. H. 1898. Contributions to the Tertiary fauna of Florida.
