especially in tlie central region, where they are 

 compressed by the pillars. 



Diameter as much as 12 or 15 millimeters, 

 but usually less. 



Lemoine and R. Douvill^ record this species 

 from Italy and Spain. It was noted from the 

 following localities in Cuba: 



7512. Ocujal. 



7513 (?). Orbitoidal limestone, outcrop where Palmer 

 trail joins Ocujal trail. 



7518. South side of Los Melones Mountain near west end. 



7519. Orbitoidal limestone from drift near top of land- 

 slide next north of Los Melones. 



7521. Limestone at top of Mogote Peak. 

 7522(?). Mogote Peak. 



7543. Limestone oiitcrop on east side of Yateras River. 

 7664. North slope of La Piedra, northeast of Jamaica, 

 northeast of Guantanamo, N. H. Darton, collector. 



Lemoine and R. Douville had only the micro- 

 spheric form of the species, but the Cuban 

 material contains megalospheric specimens. 

 The embryonic chambers are rather thick- 

 waUed and unequal in size.

Test small, discoidal, much thickened in 

 the central portion, from which it tapers rather 

 rapidly to the subacute periphery; central 

 protuberant portion with a series of large 

 pustules ranging from 5 to 12 or more m number, 

 of wliich one is usually central; reticulate be- 

 tween, the margms stellate; periphery of the 

 test thin and slightly reticulated by the walls 

 of the equatorial chambers. 



Vertical sections show the general form and 

 curvature of the surface of the test, the few 

 pillars in the central region rapidly increasing 

 in diameter toward the surface ; lateral chambers 

 with the outer wall convex, averaging about 

 three times as wide as the height in the central 

 region, with as many as 10 chambers in the 

 vertical colvunns; equatorial chambers not 

 increasing rapidly in height, those at the pe- 

 riphery not more than double the height near 

 the center. 



Horizontal sections show the embryonic 

 chambers, which are unequal, the larger one 



partially surrounding the smaller, as in the 

 subgenus N&phrolejndina of H. Douville, and 

 the equatorial chambers more or less diamond 

 shaped also as in that subgenus. In otherspeci- 

 mens the outer waU of the chamber is convex. 



Diameter, 2 to 5 millimeters. 



Spccunens seemmgly identical with this 

 species were found by O. E. Meinzer at the 

 following stations in Cuba: 



7513. Limestone outcrop where Palmer trail joins 

 Ocujal trail. 



7516. West end of Los Melones Mountain. 



7543. Limestone outcrop on east side of Yateras River. 



7554. Soiith of El Jigue, 5 miles above mouth of Yateras 

 River on west side. 



Specimens probably of this species but 

 sections not as perfect as might be desired were 

 obtained from stations 7519, limestone from 

 drift near top of landslide next north of Los 

 Melones, and 7522, Megote Peak. 



Lemome and R. Douville record this species 

 from four localities in Aquitaine — Abesse, 

 Mimbaste, St.-Etienne-d'Orthe, and Le Man- 

 ddlott; from four localities in Spain — Baena, 

 Pont du Guadalquivir, Sella, and Penaguda; 

 and from Madagascar. The stage is indicated 

 as Aquitanian but not definitely given. 



It is a very distinctive species and the Cuban 

 specimens seem to differ in no essential charac- 

 ters from those figured by Lemoine and R, 

 Douvdle. 



Exteriors of specimens from station 7664, 

 north slope of La Piedra, northeast of Jamaica, 

 northeast of Guantanamo, Cuba, are shown in 

 Plate XXXIII, figures 12 and 13.

Test of medimn size, lenticular, compara- 

 tively thick in the center, thence tapering 

 toward the sides; central portion convex, 

 changing to a concave curve toward the pe- 

 riphery; surface irregularly pustulate, especially 

 where somewhat weathered. 



The vertical section shows the general shape, 

 convex at the center, broadly rounded, thence 

 contracting rapidly toward the periphery, where 

 the curve is concave, to the rather poorly devel- 

 oped peripheral border; height or thickness of 

 the test about one-third the diameter; embry- 

 onic chamber large and very thick walled, often
