TEXTULARIA AGGLUTINANS d'Orbigny. 



Plate 19, fig. 3. 



Textularia agglutinins d'Okbigny, in De la Sagra, Hist. Fis. Pol. Nat. 

 Cuba, 1839, " ForaminifSres," p. 136, pi. 1, figs. 17, 18, 32-34. 



Description. — Test elongate, tapering, but slightly compressed lat- 

 erally, chambers high, sutures deep, outline sinuous, end view broadly 

 elliptical, wall composed of rather coarse agglutinated material, 

 aperture a narrow slit a little more than half the width of the base 

 of the chamber. 



Length 1.23 mm., breadth 0.65 mm. Cat. No. 324610, U.S.N.M. 



A single specimen here figured seems referable to this species. It 

 is from U.S.G.S. No. 6019-/, from the uppermost bed of the Culebra 

 formation, the lower limestone of the Las Cascadas section, opposite 

 Las Cascadas, Gaillard Cut. Although not so rounded in end view 

 as this species usually is in recent specimens, the general characters, 

 wall structure, high rotund chambers and lobulated outline seem to 

 place it here. 



TEXTULARIA LAMXNATA, new species. 



Plate 19, fig. 4. 



Description. — Test elongate, cuneate, tapering from the widest 

 part near the apertural end, gradually and evenly to the initial end 

 which is subacute, median line raised thence tapering rapidly toward 

 the periphery which is thin and extends out into a lamella-like 

 border, chambers numerous, wide and low, sutural lines raised, some- 

 what curved backward; border irregular, wall finely arenaceous; 

 aperture indistinct. 



Length 2 mm., breadth 1.2 mm. 



Specimen figured from U.S.G.S. No. 6010, from lower part of the 

 Culebra formation, dark clay north of Pedro Miguel Locks. Speci- 

 men rather better preserved than most from this station. The end 

 view of this specimen is mainly rhomboidal with the bordering 

 carina extending outward in a thin carina. It is in some ways sug- 

 gestive of Textularia carinata but differs in many respects from 

 that species which is also figured on plate 19, fig. 6. 



Type-specimen.-— Oat. No. 324611, U.S.N.M. 



TEXTULARIA SUBAGGLUTINANS, new species. 



Plate 19, fig. 5. 



Description. — Test subrhomboidal in front view tapering from the 

 middle toward either end, in end view oblong, sides truncated ; cham- 

 bers comparatively few, somewhat inflated, sutures conspicuously de-
