Conulites americana, new species. 



The following is a description of this species : 



Test conical, height about two-thirds the width at the base, apex broadly 

 rounded, base slightly convex, peripheral angle subacute, the peripheral 

 region standing out somewhat from the general conical mass of the rest of the 

 test; early chambers spirally arranged, later ones annular, exterior of test in 

 section tubular, central portion made up of irregularly curved chambers, more 

 or less irregularly divided into labyrinthic subdivisions; surface fairly smooth. 



Diameter at base slightly less than 2 mm. 



Type specimen (U. S. N. M. No. 328179), section from station 6902, 

 southeast section of southwest side of island near Negre Point, ele- 

 vation 360 feet, St. Bartho- 

 lomew, Leeward Islands. 

 Sectioned specimens were also 

 observed in material from the 

 following stations in Cuba: 

 3448, limestone 

 from hillside south 

 of Panupo man- 

 ganese mine, La 

 Maya, near Santi- 



ago, collected by T. 

 W.Vaughan;3478, 

 Nuevitas, collected 

 by A. C. Spencer; 

 7666, from Sierra 

 Guaso, northeast 

 of Guantanamo, collected by N. H. Darton. 



This is similar to the C. cegyptiensis Chapman from the Eocene of 

 Egypt and Italy, but differs in its general proportions and in the 

 flange-like extension of the peripheral border at the base. 



Gypsina vesicularis (Parker and Jones). 



Orbitolina vesicularis Parker and Jones, Ann. Mag. Nat. Hist., ser. 3, vol. 6, p. 31, No. 5, 1860. 

 Tinoporus vesicularis Carpenter, Introd. Foram., p. 224, plate 15, figs. 1 to 4, 1862; Parker 



and Jones, Ann. Soc. Mai. Belg., vol., 11, p. 98, 1876. 

 Gypsina vesicularis Carter, Ann. Mag. Nat. Hist., ser. 4, vol. 20, p. 173, 1877; H.B.Brady, 



Rep. Voy. Challenger, Zoology, vol. 9, p. 718, plate 101, figs. 9 to 12, 1884; Hill, 



Bull. Mus. Comp. Zool., vol. 34, p. 147, 1899. 



Parker and Jones and also Hill record this species from the Bowden 

 marl of Jamaica, but I have failed to find it in that I have examined. 

 Parker and Jones mention a single specimen, 4.75 mm. in size. 



Gypsina inhaerens (Schultze). 



Gypsina inhcerens (Schultze) H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, p. 718, plate 

 102, figs. 1 to 6, 1884. 



Specimens which are evidently of this species were collected at three 

 stations: several specimens at Bluff 3, Cercado de Mao; rare at Bluff 

 2, Cercado de Mao; and Zone H, Rio Cana, Santo Domingo.
