^ Under the name Orbitaides kempt (Trans. Amer. Inst. Min. Eng., vol. 51, 

 p. 13, figs. 5, 6, 1916) Dr. Marjorie O'Connell figured specimens from sections 

 cut from a limestone quarry at Arroyo Seboruco, 12 miles from Felton, Cuba. 

 Several sections of Dr. O'Connell's original material have been cut and examined. 

 Figure 5 of Dr. O'Connell's paper represents Lepidocyclina favosa Cushman, 

 and figure 6 shows a typical vertical section of L. yurnagunensis Cushman. 

 Besides the species figured in Dr. O'Connell's paper, there is also L. yurna- 

 gunensis var. morganopsis Vaughan, n. var. It is apparent that at least two or 

 more species and one variety exist in the material from this locality. As the 

 description of O. kempt is so' generalized that no one species can be definitely 

 recognized, and as two different species were figured without the designation 

 of a type, it seems impractical to use the specific name kempi. The horizon of 

 the material is Oligocene.
