ART. 14 FORAMINIFEEA FROM TRINIDAD — CUSHMAN AND JAEVIS 13 



Kecent species and is fairly abundant in the material from Lizard 

 Springs, but it was not found in the other collections. 



Genus AMMOBACULITES Cushman, 1910

 AmmobacuHtes coprolithiforme Cushman, Trans. Roy. See. Canada, sec. 4, p. 



130, pi. 1, figs. 6, 7, 1927. 



Test elongate, early portion close coiled, later chambers rectilinear, 

 of uniform width, generally circular in section; sutures distinct, 

 depressed ; wall arenaceous but smoothly finished ; aperture circular^ 

 terminal. 



This species originall}^ described from the Cretaceous of Europe 

 has already been recorded from the Upper Cretaceous of western 

 Canada. Identical specimens occur in the Cretaceous of Trinidad^ 

 and the striking similarity of these may be seen by comparison of 

 the hgures of the specimens of the two regions. It is quite probable 

 that some of the European specimens referred to Ammohaculites 

 agglutinans may belong to Schwager's species. The figures seem to 

 be similar. 



Subfamily Lituolinae 

 Genus CYCLAMMINA H. B. Brady, 1876

Plate 3, Figures 6 o, 6 



Descript/ion. — Test comparatively large, close coiled, i^eriphery 

 somewhat lobulated and subacute, or at least compressed; chambers 

 numerous, usually 10 to 12 in the last-formed coil; sutures distinct, 

 slightly depressed, usually sigmoid; wall smooth, distinctly arena- 

 ceous, thin, with a very even cancellated structure of the interior 

 showing through; aperture consisting of a low curved arch at the 

 base of the apertural face with numerous supplementary rounded 

 openings scattered over the central portion of the apertural face, 

 often with slightly raised borders. Length, 2 ; breadth, 1.25 ; thick- 

 ness, 0.85 mm. 



Holotype.—U.S.'^M. No. 73815 (Cushman Coll. No. 15280), from 

 Upper Cretaceous, from pit at Lizard Springs near Guayaguayare, 

 fcoutheastern Trinidad, British West Indies. 



RemMrhs.— This is fairly common in the Lizard Springs Creta- 

 ceous, and is especially marked by the thin outer wall and the distinct
