Original Description: " Specimens referred to by Shokina as H. liebust var., characterized mainly by sgmoidal sutures, are also present in our material. They are considered to constitute a new species and are described below as H. trinitatensis. [p.411]: "The subelliptical closely coiled test is composed of four to six chambers which are inflated and increase gradually in size as added. They are longer than broad and slightly separated peripherally, especiallyin the las ontogeneticstages where they become somewhat bulbous. The sutures are sigmoidal, distinct, and fairly depressed. Spines, mostly broken off, are long and hollow, and always situated below the anterior sutures. "The aperture is an arched tripartite slit with broad lateral projections extending into the umbilicus. The surface is smooth and the walls are finely perforate. Maximum diameter without spines: 0.4 - 0.7 mm. (holotype .54 mm.). Length of spines: ± 0.2 mm. (holotype 0.18 mm.)
