position, i.e., extending from the ventral side over the periphery onto 

 the dorsal side and having a small protective rim above it. 



Because of Barker's assignment (1960, p. 192, pi. 93, fig. 8) of one 

 of Brady's figures of "Truncatulina wuellerstorji" to Planulina bradii 

 Tolmachoff with Cibicides rugosa Phleger and Parker as a synonym, 

 I have considered the inclusion of both P. bradii from the Miocene of 

 Colombia and C. rugosa from the Recent of the northwestern Gulf of 

 Mexico. Both are surely related morphologically but seem to be 

 separable from the present specimens.

This species, described from the Pliocene of Kar Nicobar [Car 

 Nicobar Island], is characterized by its coarse pores, usually less 

 well developed on the convex (ventral) side than on the flat (dorsal) 

 side. 



The species is found in the present collections but not commonly. 



CIBICIDES FLORIDANUS (Cushman)

Rare specimens are referred to this widely recorded species, which 

 was first described from the Miocene of Florida. 



By comparison with other species of the genus, this species is 

 flatter and has a sharper yet not keeled periphery. Like Cibicides 

 cicatricosus, it is rather coarsely porous on the flat (dorsal) side and 

 only finely porous on the opposite side.
