Test much elongated, slender, tapering, greatest width toward the 

 apertural end; chambers distinct, inflated, subglobular, increasing 

 rather uniformly in size, the early ones somewhat less inflated; 

 sutures distinct, depressed, more so between the later chambers ; wall 

 smooth; aperture radiate, terminal. Length, 0.8-1.25; diameter, 

 0.15-0.25 mm. 



This species we have already recorded from Trinidad as Dentalina 

 cf. adolphina. It seems to fit rather well the species described by 

 Reuss from the Cretaceous of Europe and should be placed under 

 his species. 



DENTALINA sp. (?) 



Plate 9, Figure 13 



Tlie peculiar broken specimen figured is given simply that the 

 record of it may be available for future workers on the Cretaceous 

 of this area. It has very thick limbate sutures as one of its main 

 characters. 



DENTALINA sp. (?) 



Plate 10, Figure 3 



The broken specimen figured has very coarse costae, which project 

 somewhat at the base of each chamber and are in the later chambers 

 projected as short spines. No complete specimens were found.

Test elongate, slightly arcuate; chambers increasing gradually in 

 length as added until the final chamber is often twice as long aS 

 broad; sutures distinct, slightly depressed in the later portion; wall 

 smooth ; aperture terminal, radiate, very slightly projecting. Length, 

 1.6; diameter, 0.2 mm. 



This species was originally described by d'Orbigny from the Cre- 

 taceous chalk of the Paris Basin, and it has been very widely recorded 

 from Europe and elsewhere. It is a common species in Trinidad and 

 in the Upper Cretaceous of the Gulf Coastal Plain of the United 

 States.
