FOSSIL FORAMINIFERA FROM THE WEST INDIES. 51 



Nummulities antillea, new species. 

 (Plate 4, Figures 1, 2.) 



The following is a description of this species: 



Test large, much compressed, only partially involute, the last coil broad 

 and thin, surface with the suture lines raised, evenly curved, with a trace of 

 papillate ornamentation along the ribs, peripheral margin somewhat thickened 

 ,and rounded. 



Diameter 15 to 18 mm. or more. 



Type specimens (U. S. N. M. No. 328182) fromU. S. G. S. station 6924, 

 from bed of limestone at top of described section, point on northwest 

 side of St. Jean Bay, St. Bartholomew, collected by T. W. Vaughan. 

 At this station specimens are abundant. The sectioned specimen, 

 plate 4, figure 2, which seems to represent a young or the central por- 

 tion of this species, is from U. S. G. S. No. 6895, spur on southwest 

 side of cay northwest of St. Jean Bay, St. Bartholomew, 170 feet above 

 sea-level. It may be noted that Orthophragmina occurs at both of 

 these stations, although not the same species. A few of the equatorial 

 chambers of Orthophragmina, probably 0. antillea, may be noted in 

 the upper right-hand corner of figure 2. 



This seems to be one of the larger of our American species of Num- 



mulites. 



Nummulites parvula, new species. 



(Plate 4, Figures 3 to 6.) 

 The following is a description of this species : 



Test small, closely involute, increase in breadth of test slight with each 

 coil, sutures simple, slightly curved, test rather evenly lenticular, biconvex, 

 chambers thick-walled, usually consisting of 4 or 5 coils. 



Diameter up to 4 mm. 



Type specimen (U. S. N. M. No. 328183) from U. S. G. S. station 6903, 

 220 feet above sea-level, N. 67° E. from summit of Negre Point, across 

 low saddleback of point, St. Bartholomew. The vertical sections may 

 not represent this species, although they are very similar, but some- 

 what smaller. They are all from St. Bartholomew; plate 4, figures 

 4, 5, from U. S. G. S. No. 6924, from bed of limestone top of section, 

 point on northwest side of St. Jean Bay; figure 6 from 6921, point 

 between Governor's Bay and Nigre Point. 



Nummulites species. 

 In the Cuban material species of Nummulites occasionally occur, 

 but are abundant at only one station. From station 3567, lowermost 

 100 feet of Tertiary running in above serpentine, northwest of Recreo, 

 Matanzas Province, Cuba, collected by A. C. Spencer, Nummulites is 

 very common, but the species have not been identified. This abun- 

 dance with accompanying species of Orthophragmina and absence of 

 Lepidocyclina would seem strongly to indicate the Eocene age of this 

 particular material.
