FOSSIL FORAMINIFERA FROM THE WEST INDIES. 27 



It is interesting to note that many of the species fit much more 

 closely the original figures and descriptions given by d'Orbigny in his 

 Cuba paper (d'Orbigny, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, 

 1839, "Foraminiferes") than they do any other later figures and 

 descriptions, either of these same or other species. In fact, many of the 

 d'Orbignyan species originally described in the above paper have since 

 been changed by subsequent authors, so that the later figures assigned 

 to such species are not at all specifically like the originals. After care- 

 ful comparison it has seemed best to reestablish several of d'Orbigny 's 

 species, such as Polystomella lanieri and others, as fitting the present 

 material under consideration much more definitely than do the recent 

 species under which they have been placed as synonyms. 



Similarly, in the matter of the genus Asterigerina d'Orbigny, it has 

 seemed best to use that name here. While it is true that Discorbis has 

 species which have "asterigerine" developments on the ventral side, 

 and while Amphistegina also has similar characters, yet here are several 

 species certainly not closely related to Discorbis nor yet with the 

 highly developed characters of Asterigerina. Under such circum- 

 stances, as they fit d'Orbigny's genus Asterigerina perfectly, that name 

 is here applied to them. 



Only those specimens are figured which are believed to be new. For 

 the others, a reference to figures, either to d'Orbigny or other authors, 

 is given. A few species must be left in a questionable condition, either 

 because they are uniques or are too worn or broken to give full details. 



A table is given showing the distribution in the different localities. 



JAMAICA. 



In his Geology of Jamaica, Hill 1 gives records of Foraminifera, 

 identified by Dr. R. M. Bagg, from a number of localities and horizons. 

 The collections available for the present work are limited to the Bowden 

 marl from Bowden, Jamaica. In 1876 Jones and Parker, 2 gave a list 

 of the species they found in the Bowden marl, and Brady, in the same 

 volume (p. 309), described a new species from the same formation. 

 The list given by Jones and Parker is as follows : 



Nodosaria raphanistram Linne\ Cristellaria italica Defrance. 



Dentalina acicula Lamarck. Tinoporus vesicularis Parker and Jones. 



Vaginulina striata d'Orbigny. Bulimina ovata d'Orbigny. 



Frondicularia complanata Defrance. Cuneolina pavonia d'Orbigny. 



Cristellaria rotulata Lamarck. Vertebralina (Articulina) striata d'Orbigny. 



cultrata Montfort. Lituola soldani Parker and Jones.
