Gypsina globulus (Reuss).

 1884. 



In the material from U. S. G. S. No. 6966, southwest shore of Cro- 

 cus Bay, Anguilla, occasional specimens occur which seem to belong 

 to this species. A median section of a small specimen is shown here. 

 There does not seem to be the definite radial arrangement of chambers 

 that is usually the case in the fossil specimens of this species. I have 

 the species in fossil condition from Santo Domingo. Two specimens 

 were found at Bluff 2 and a single one at Bluff 3, Cercado de Mao. 



Gypsina globulus (Reuss) var. pilaris (H. B. Brady). 

 (Plate 9, Figures 1, 2.) 



Tinoporus pilaris H. B. Brady, Ann. Soc. Mai. Belg., vol. 11, p. 103, 1876. 

 Gypsina globulus Hill, Bull. Mus. Comp. Zool., vol. 34, p. 147, 1899. 



The following is a description of this variety: 



Test spherical, comparatively large, exterior appearing smooth, but when 

 magnified showing an areolate surface due to the walls of the chambers; wall 

 calcareous, perforate ; chambers in radial columns increasing in diameter from 

 the center to the periphery. 



Diameter up to 4 mm. or more. 



Brady described this variety as a species of Tinoporus from the 

 Miocene of Jamaica. It is probably the most conspicuous species and 

 is very abundant in the Bowden material. The variety differs from 

 typical G. globulus mainly in size, the typical having a much smaller 

 test. Plate 9, figure 2, gives a general idea of the internal structure of 

 the test. 



There are specimens from station 3446, first deep cutting on railroad 

 east of La Cruz, near Santiago, Cuba, collected by T. W. Vaughan, 

 which in size, shape, and general characters seem very close to this 

 variety. The internal structure, as far as it is preserved, seems also 

 to be identical with the Bowden material. The geologic occurrence of 

 these specimens is in the Miocene La Cruz marl. 



Gypsina species. 



Sectioned specimens from 3 stations in Cuba showed what seem to be 

 sections of Gypsina. They are associated in each case with Lepidocy- 

 clina and Carpenteria. The stations are 7513, outcrops where Palmer 

 Trail joins Ocujal Trail; 7521, limestone in place, top of Mogote Peak; 

 and 7522, also Mogote Peak; collected by 0. E. Meinzer.

Specimens from the Bowden marl, Bowden, Jamaica, and from 

 station 3461, marl from the gorge of Yumurf River, Matanzas, Cuba, 

 collected by T. W. Vaughan, seem to be identical with the species
