38 GEOLOGY AND PALEONTOLOGY OF THE WEST INDIES. 



Type specimen from the Miocene Bowden marl, Jamaica (U. S. N. M. 

 No. 328178). 



This is a fairly common species at this locality and is the one from 

 Bowden referred to by various authors as Cristellaria calcar. It is not 

 typical C. calcar and seems to be distinctive in its size, form, and 

 ornamentation. The nearest approach to it is perhaps the form 

 described from the Carribbean by Goes (Kongl. Svensk. Vet. Akad. 

 Handl., vol. 19, No. 4, p. 49, plate 3, figs. 3, 50, 51, 1888) under the 

 name Nodosarina crepidula var. cassis (Fichtel and Moll).

 Challenger, Zoology, vol. 9, p. 554, plate 71, figs. 6, 7, 1884. 



A single very typical specimen of this species was obtained from the 

 Bowden marl, Bowden, Jamaica. Brady's records of its occurrence as 

 a recent species include the Fiji Islands, Torres Strait, and the Philip- 

 pines. 



Cristellaria italica (Def ranee).

 21, 31, plate 1, figs. 41, 42, 1865; Jones and Parker, Ann. Soc. Mai. Belg., vol. 11, 

 p. 98, 1876; H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, p. 544, plate 68, 

 , figs. 17, 18, 20, 23, 1884. 



Jones and Parker, in their list of species from the Bowden marl, 

 record a single specimen of this species, measuring about 6 mm. in 

 length. That is about the size of large recent specimens from this 

 same general region. I have not found the species in the material I 

 have examined from the Bowden, but it occurs in material from the 

 Panama Canal Zone. 



Polymorphina species. 

 (Plate 8, Figure 4.) 



In the sections from station 7664, north slope La Piedra, northeast of 

 Jamaica, northeast of Guantanamo, collected by N. H. Darton, there 

 are specimens of a large species of Polymorphina, with fairly thick 

 walls. One of these is figured in the reference given above.

A few specimens of this common species occur in the Bowden, 

 Jamaica, material, accompanied as usual by some specimens which
