Original Description

" Globigerina. Testa suborbiculata, convexa, alba, creberrime rugosa, spira convexo-obtusa, anfractibus tribus, distinctis; loculis quinis, oblongatis; suturis excavatis; apertura magna, in umbilico.

Coquille globuleuse, discoïde, élevée, partout rugueuse, les rugosités dues au pourtour saillant des nombreux trous dont chaque loge est criblée. Spire convexe, à sommet très obtus, composée de trois tours bien distincts et formée, dans J'état adulte, de dix à douze loges. Loges ovales, dans le sens de J'axe, au nombre de cinq au dernier tour, très séparées, et laissant à leur centre un profond ombilic. Ouverture en croissant, très large, placée sur plus de la moitié de la dernière loge, dans l'ombilic même. Couleur, blanc ou blanc-jaunâtre.

Description of lectotype. The globose test consists of about 13 chambers arranged in a fairly high, tightly coiled trochospire of about three whorls. There are about four chambers-in the early whorls increasing to five chambers in the ultimate whorl. The equatorial profile is subcircular and the equatorial periphery weakly lobulate. The axial profile is broadly rounded, with the dorsal side moderately convex. The axial periphery is smoothly rounded. The chambers are appressed, inflated, moderately embracing, reniform in dorsal aspect and ovoid in axial view. Ali the dorsal and ventral sutures are distinct and moderately depressed. The intercameral sutures are slightly curved to nearly radial both ventrally and dorsally, and the spiral suture is lobulate. The umbilicus is weli marked, moderately broad and probably deep (infilled in the lectotype). The aperture is an interiomarginal, umbilical arch leading directly into the umbilicus. No apertural lip or rim is visible on the lectotype. The wall is moderately and uniformly perforate and has a practically smooth surface. [Banner & Blow 1960]

Diamètre ½ millim. Maximum diameter of lectotype: 0.48 mm. [Banner & Blow 1960]

Extra details from original publication
Par sa spirale bien distincte, composée d'un grand nombre de loges, par les cinq loges de son dernier tour, cette espèce a beaucoup d'analogie avec notre G. fragilis fossile, dans les environs de Dax; mais, percée de trous bien plus grands, elles' en distingue par sa contexture plus poreuse, plus rugueuse, et par son ouverture bien plus largement ouverte.

Taxonomic remarks. This species was first described by d'Orbigny from recent marine sands of Cuba, Martinique and Guadaloupe. A tube originally containing eight specimens was found in the d'Orbigny collection. This tube had d'Orbigny's original label pasted on the back of the mount and bore the following inscription in d'Orbigny's handwriting:

IV 19-21 Globigerina Dutertrei
The locality and bibliographic numerals (probably in Terquem's handwriting) were inscribed on the front of the mount:
Cuba: TYPE 84. IV. 19. 21
Of the eight specimens originally present, one was completely lost, five were merely fragmentary, and one was broken but still recognisable; the single remaining undamaged specimen, here figured, was therefore isolated and is designated here as lectotype.
The specimen illustrated by Brady (1884) probably belongs to this species but the last chamber is misshapen and is misplaced in the progression of the spire. However, except for this abortive last chamber, Brady's form agrees in general characters with the lectotype.
The form ascribed by Ovey (in Wiseman and Ovey, 1950, p. 65, pI. 2, figs. la-c) to this species is referable to a Globorotalia (Turborotalia) and is probably conspecific with the form described by Blow (1959) as G. (T.) acostaensis. [Banner & Blow 1960]

Remarks.-This species is referable to the genus Globigerina d'Orbigny as restricted by Banner and Blow (1959). No supplementary apertures are present and the aperture is purely umbilical, notwithstanding the slightly abortive nature of the final chamber in the lectotype. This species has been observed by us in the Pleistocene of S. E. Sicily and in the sub-recent deposits off the coast of Nigeria as well as in recent material collected by the "Discovery"" and the ""Challenger"" Expeditions. [Banner & Blow 1960]
