pustulate throughout, but these protuberant spots of small size and covering 

 the larger part of the area more or less evenly; surface otherwise smooth; 

 periphery thin. 



Vertical sections show the general form and curvature of the test, pillars 

 entirely lacking, lateral chambers with the outer surface convex, three or four 

 times as wide as high; 6 to 10 chambers in a vertical column. 



Horizontal sections show the embryonic chambers, which are unequal, the 

 larger curved about the smaller semicircular one; equatorial chambers irregu- 

 larly hexagonal. 



Diameter 2 to 5 mm. 



Distribution. — L. sumatrensis was obtained in Cuba by O. E. Meinzer 

 at the following stations: 7513, limestone outcrop where Palmer Trail 

 joins Ocujal Trail; 7516, west end Los Melones Mountain; 7519, lime- 

 stone from drift near top of landslide next north of Los Melones; 7543, 

 limestone outcrop, east side of Yateras; 7554, south of El Jigue, 5 

 miles above mouth of Yateras River on west side; and by N. H. Darton 

 at 7664, north slope of La Piedra, northeast of Jamaica, northeast of 

 Guantanamo. 



This species was described by Brady from Sumatra. It is recorded 

 elsewhere in the East from Formosa and the East Indies, and Lemoine 

 and R. Douville record it from Rosignano, Montferrat, Pi&nont, 

 Italy; Ba4na, Pont du Guadalquiver, Penaguila, and Sella, Spain; and 

 Saint-Etienne-d'Orthe and Mandillot, near Dax, France, probably 

 Aquitanian in age. 



In the Cuban material it occurs usually in company with L. morgani, 

 and in this connection it is interesting to note that both species are 

 given by Lemoine and R. Douville' from all four of the stations in 

 Spain and from three of the four stations in France. 



This species may easily be distinguished from L. morgani by its lack 

 of pillars. The pustulate appearance of L. sumatrensis is due to the 

 convex surface of the lateral chambers, those of adjacent columns being 

 of unequal height at the surface. 



Lepidocyclina crassata, new species. 

 (Plate 11, Figures 4, 5.) 



The following is a description of this species: 



Test of medium size, lenticular, comparatively thick in the center, thence 

 tapering toward the sides; central portion convex, changing to a concave 

 curve toward the periphery; surface irregularly pustulate, especially where 

 somewhat weathered. 



Vertical section shows the general shape, convex at the center and broadly 

 rounded, thence thinning rapidly toward the periphery, where the surface is 

 concave, to the rather poorly developed peripheral border; height or thickness 

 of the test about one-third the diameter. Embryonic chamber large and very 

 thick-walled, often showing 1 or 2 accessory chambers, also thick-walled and 

 rather conspicuously perforate; young specimens show that for a time the 

 embryonic chamber is the greater part of the test. Equatorial band of cham- 

 bers rather large, even at the beginning, the outer wall convex and coarsely 

 perforate. Lateral chambers comparatively thick-walled, several times as 

 broad as high, somewhat lenticular in section, highest in the middle; thence
