Dimensions. c-c (series)= 3–5 mm; c-c (between series)= 3–6 mm; s/mm=5–7/2.

Description. Massive-lamellar and thamnasterioid colony; corallites grouped in concentric series in juvenile colonies, becoming meandroid in later stages; isolated calices occur frequently; gemmation intracalicinal; septa confluent, straight, subcompact, porous in places, nearly equal in thickness; lateral surfaces covered with rounded granules, varying in size and shape, or long spiny ornamentations; about 10 septa reach the calicinal center, where their inner ends may terminate into claviform thickenings or form prolongations, uniting with neighbouring septa; columella rudimentary or made of a few papillae; synapticulae present throughout the colony; wall synapticulothecal, incomplete; endothecal dissepiments thin, vesicular, rare.

Remarks. In having corallites arranged in concentric series, a small papillose columella, compact septa with beaded margins, and a synapticulothecal wall which is incomplete, the material described by Vaughan (1899) as Mesomorpha catadupensis seems to rather correspond to the genus Cyathoseris .

Type locality of species. Campanian-Eocene of Jamaica (Catadupa beds) .

Distribution. Upper Santonian of France, Campanian-Eocene of Jamaica (Catadupa beds and new material), Paleocene of Egypt.

New Material. Maastrichtian of Jamaica, NMNH, Coates coll., sample nos.: 379 (=Jerusalem Mountain Inlier); 495a; 520 (=Ducketts Land Settlement).
