50 SHALLOW-WATER FORAMINIFERA OF TORTUG.iS REGION. 



adult. This is lost as the test becomes larger and in the adult 

 there is practically no coil. Both young and adult specimens are 

 shown (plate 7, figs. 11 and 12). 



Genus ANOMALINA d'Orbigny, 1826. 

 Anomalina edwardsiana (d'Orbigny). 



(Plate 8, Figures 1, 2.) 



RoacUina edtvardsiana d'Orbigny, in De la Sagra, Hist. Fia. Pol. Nat. Cuba, 1830, "Forami- 

 nif^res." p. 106. pi. 6, figa. 8 to 10. 



Test biconvex, unequally so, the dorsal side flatter than the ventral ; periph- 

 ery very slightly lobulated; the chambers visible on both sides to the center; 

 chambers numerous, 8 or 9 in the last-formed coil, distinct, those of the 

 ventral side with the sutures more limbate and very slightly depressed, those 

 of the ventral side not limbate, but more depressed, wall coarsely punctate; 

 aperture an elongate, curved slit on the ventral side of the last-formed cham- 

 ber, with a slight, overhanging thin lip; color white. 



Diameter of the Tortugas specimens up to 0.50 mm. 



D'Orbigny described this species from Cuba and Jamaica. It has 

 occurred at several stations in the Tortugas collection, although 

 usually in very few numbers. In some of its characters it suggests 

 T. wuellerstorfi Schwager. 



Anomalina ammonoides (Reuss) ? 

 (Plate 7, Figure 10.) 



There are single specimens from two stations which seem to be 

 at least related to this species. The figure of one of these is given. 

 The chambers are fewer in number and the coils less than the typical 

 form assigned to this species. 



Genus PULVINULINA Parker and Jones, 1862. 



Pulvinulina menardii (d'Orbigny).

Roialina cultrata d'Orbigny, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, 1839, "Forami- 

 nif^res," p. 90, pi. 5, figs. 7 to 9. 



Test plano-convex, compressed, dorsal side slightly convex, ventral side 

 flat or somewhat concave, umbilicate, peripheral margin thin, slightly lobu- 

 lated, carinate; chambers usually 6 in the last-formed coil; sutures somewhat 

 depressed, especially below, on the dorsal side limbate and curved, ventrally 

 simply depressed, straight, in a radial position; wall usually smooth and 

 punctate, but sometimes slightly granular; aperture a rather well-developed 

 opening at the umbiHcal end of the chamber, with a projecting valvular Up. 



Diameter of the Tortugas specimens not exceeding 0.75 mm.
