24 SHALLOW-WATER FORAMINIFERA OF TORTUGAS REGION. 



This species occurred at 5 stations in the area, usually those of 

 greater depths. I have failed to find it in other material from the 

 West Indies or Caribbean, although it is a striking form and could 

 hardly be overlooked. With its peripheral spines it resembles such 

 species as T. carinata d'Orbigny, T. horrida Egger, and T. sagittula 

 Def ranee var. Jislulosa H. B, Brady, but is different from any of these. 



It is named in honor of Dr. Alfred G. Mayor, Director of the 

 Tortugas Laboratory of the Carnegie Institution of Washington. 



Teztularia floridana, new species. 



(Plate 1, Figure 7.) 



Textularia transversaria Flint (not H. B. Brady), Rep. U. S. Nat. Mus., 1897 (1899), p. 283, 

 pi. 28, fig. 4. 



Test elongate, two to three times as long as wide, much compressed, 

 periphery acute, the ends of the chambers forming tubular projections, but 

 often broken, showing a truncate or concave area which is hollow; the initial 

 end rather sharply pointed, the apertural end broadly rounded; chambers 

 numerous, thickest near the center, increasing somewhat in height toward 

 the apertural end ; sutures indistinct, slightly if at all depressed ; .wall finely 

 arenaceous, smooth ; aperture small, rounded, at the base of the inner margin 

 of the last-formed chamber. 



Length slightly more than 1 mm. 



There is a single specimen of this species from station 42, in 18 

 fathoms. It is very typical and like those collected from off 

 Florida. From the other records, it is evidently not a species' of 

 very shallow water, and this may account for its rarity in the 

 Tortugas collection. There are records for its occurrence as far 

 north as the coast of South Carolina. 



Textularia conica d'Orbigny. 



(Plate 2, Figure 4.) 



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

 niferes," p. 143, pi. 1, figs. 19, 20. — H. B. Brady, Rep. Voy. Challenger, Zoology, 

 vol. 9, 1884, p. 365, pi. 43, figs. 13, 14, pi. 113, fig. 1.— Cushman, Proc. U. S. Nat. 

 Mu3., vol. 59, 1921, p. 50, pi. 11, figs.,4 to 6. 



Test usually wider than high, triangular in front view, broadly oval in 

 end view, shghtly compressed, the apex bluntly pointed; chambers compar- 

 atively few, distinct; sutures distinct, slightly depressed; wall arenaceous, 

 smooth, or slightly roughened; aperture a narrow slit at the base of the 

 inner margin of the last-formed chamber, with a slight overhanging lip; 

 color grayish-white. 



Length of the Tortugas specimens usually less than 1 mm. 



Specimens seem to be very rare in all the Tortugas material 

 examined. The original figure given by d'Orbigny is more or less con- 

 ventionalized, showing a smooth surface, but otherwise gives the 

 general shape fairly well. He recorded it from Cuba and Jamaica, 

 and I have had material from the latter locality. It occurs elsewhere 

 in the Gulf of Mexico and in the Caribbean. According to the 

 records, it seems to be a species of warm, tropical waters.
