FOSSIL FORAMINIFERA FROM THE WEST INDIES. 69 



being " young examples, in a Triloculine condition" is erroneous, as 

 the young of Triloculina is quinqueloculine in the microspheric form 

 at least, while the young of Quinqueloculina is quinqueloculine in both 

 forms, microspheric and megalospheric. Our specimens, too, are 

 larger than those figured by Brady as T. boueana. 



Triloculina fichteliana d'Orbigny. 



Triloculina fichteliana d'Orbigny, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, " Foraminiferes," 

 p. 171, plate 9, figs. 8 to 10, 1839. 



A single specimen referred to this species was found in the material 

 from Bluff 3, Cercado de Mao, Santo Domingo. 



Biloculina species. 



Two small specimens of Biloculina were found in the material from 

 Bluff 3, Cercado de Mao, but are not in condition to identify them 

 specifically. A single small specimen was also found in marl from 

 station 3461, gorge of Yumuri River, Matanzas, Cuba, collected by 

 T. W. Vaughan. Specimens referred to B. bulloides d'Orbigny were 

 obtained from the Miocene of the Panama Canal Zone and from 

 Florida. 



Vertebralina cassis d'Orbigny. 



Vertebralina cassis d'Orbigny, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, ''Foraminiferes/ 1 

 p. 51, plate 7, figs. 14, 15, 1839. 



From the material from Zone H, Rio Cana, Santo Domingo, a single 

 specimen was obtained. It is of the form figured by d'Orbigny as V. 

 cassis and has the typical ornamentation, although somewhat eroded. 



Vertebralina striata d'Orbigny. 

 (Plate 14, Figure 3.) 



Jones and Parker record this species in their list of Foraminifera 

 from the Bowden marl, Jamaica. I have found a single specimen in 

 my material, figured here. 



Peneroplis pertusus Forskal var. discoideus Flint. 



Peneroplis pertusus var. discoideus Flint, Ann. Rep. U. S. Nat. Mus., 1897, p. 304, plate 49, 

 figs. 1, 2, 1899. 



These specimens from Bluff 3, Cercado de Mao, Santo Domingo, 

 are identical with this peculiar variety described by Flint from the 

 shallow water of Key West Harbor, Florida. 



Peneroplis pertusus Forskal variety. 



A single specimen from Bluff 3, Cercado de Mao, has the typical 

 form of Orbiculina adunca, but, as the chambers throughout seem to be 

 undivided, the specimen is a true Peneroplis.
