FOSSIL FORANIMIFERA FROM THE WEST INDIES. 55 



Type specimen (U. S. N. M. No. 328187) from Nuevitas, Cuba, col- 

 lected by A. C. Spencer. 



This species in general appearance resembles 0. marthce Schlum- 

 berger, especially in its characteristic surface ornamentation, but the 

 vertical section seems to be very different from that figured by Schlum- 

 berger. 



Orthophragmina pustulate, new species. 

 (Plate 9, Figures 6, 7; Plate 10, Figure 1.) 



The following is a description of this species : 



Test circular, lenticular, thickest in the middle, thence gradually thinning 

 toward the periphery, which is without a carina or thinner portion, thickness 

 about one-fifth the diameter; surface finely pustulose, papillae larger and more 

 numerous near the central region, thence gradually decreasing in size and 

 number toward the periphery. 



Vertical section shows the general form, equatorial band very thin, increas- 

 ing hardly at all toward the periphery, pillars numerous, somewhat thickened 

 toward the surface. 



Horizontal section shows equatorial chambers elongate, rectangular, 

 length about three times the breadth, annuli irregular in width, pillars irregu- 

 larly rounded, remote, largest in center, decreasing gradually in size toward 

 the periphery, intermediate space filled with the irregularly polygonal lateral 

 chambers. 



Diameter 3.5 to 5 mm. 



Type specimen (U. S. N. M. No. 328188), section from station 3567, 

 lowermost 100 feet of Tertiary running in above serpentine, northwest 

 of Recreo, Matanzas Province, Cuba, collected by A, C. Spencer. 

 Specimens, also apparently of this species, were obtained at station 

 3448, limestone from hillside south of Ponupo manganese mine, La 

 Maya, near Santiago, Cuba, collected by T. W. Vaughan. 



This is a larger, flatter species than 0. cubensis and is easily distin- 

 guished in the sections. 



Orthophragmina antillea, new species. 

 (Plate 1, Figure 1; Plate 2, Figures 2 and 3; Plate 4, Figures 2 and 4.) 



The following is a description of this species : 



Test flattened, octagonal, surface with 8 raised ribs radiating from the 

 central, somewhat raised umbo to the periphery, triangular areas between 

 thin and flattened; umbpnal area raised and rounded, with definite pillars 

 appearing as differences in coloration in the type, radial ribs with numerous 

 raised areas and pillars scattered along their whole length; diameter about 

 12 mm. 



Vertical sections show the greater diameter of the equatorial chambers at 

 irregular intervals and the irregular, almost serrate character of the dorsal 

 and ventral surfaces due to the fine projections of the surface, especially 

 along the ribs. 



Horizontal sections through the equatorial chambers were obtained only 

 in small fragmentary bits, but enough to show the typical rectangular cham- 

 bers of the genus.
