Original Description Concha subglobular, formada por dos vueltas de espira poco elevadas, lado dorsal menos elevado que el ventral con cuatro a cinco cámaras globosas en la última vuelta, las que aumentan rápidamente de tamaño según se forman, la última cámara tiene la tendencia de ser más pequeña y trata de cubrir la región umbilical; esta cámara varia de tamaño y forma en los individuos y le dá a la concha un aspecto morfológico poco estable, suturas profundas; pared perforada y finamente reticulada; abertura pequeña en la base de la porción interna de la última cámara. Size: Diametro 0.62 mm.; altura 0.50 mm. Extra details from original publication La presente especie nueva se distingue de Globigerina carteri Karrer en su forma más globosa, más comprimida por la cara dorsal, por ser menos umbilicada y por poseer una camarita final más desarrollada, que trata de cubrir la región umbilical. Aparentemente es una forma limitada a los mares profundos de la región Caribe-antillana
