FORAMINIFERA OF THE ATLAISTTIC OCEAN.

examiuation of Flint's mounted slides shows that this is the form 

 noted by him under T. concava from this station, as given in the 

 above reference. In some of its characters it is related to T. concava, 

 and in its reentrant at each side of the test reminds one of T. rugosa 

 Reuss, but in most of its characters it is very different from any of 

 these. The sides are very concave in the middle, but in end view 

 the breadth is nearly equal to the width. The last two or three 

 chambers are much inflated and do not show the concavity at the 

 sides. From the material examined from the western Atlantic this 

 species seems to be very limited in its distribution, being found 

 nowhere but at this one station. 



Tcxtularia albatrossi — material examined. 



TEXTULARIA CONCAVA Karrer. 



This species is recorded by Wright and others off the southwest of 

 Ireland and by Heron-Allen and Earland from four stations in the 

 Clare Island region. I have seen no Atlantic material which I 

 should refer to the typical form of this species.

 (1899), p. 283, pi. 28, fig. 5 (part). 



Description. — Test about twice as long as wide, tapering from the 

 bluntly rounded initial end, very much compressed, sides flat, 

 periphery flattened at right angles to the sides; chambers increasing 

 slightly in height as added, rectangular; sutures distinct but not 

 depressed, wall arenaceous with a large proportion of cement, vcjy 

 smoothly finished; color gray. 



Length up to 1 mm. or slightly more. 



Distribution. — Type-specimen (U.S.N.M. No 17045) from Alba- 

 tross station D2641, in 60 fathoms (110 meters), off Carysfort 

 Light, Florida. It has occurred at two other stations — D2639, in 56 

 fathoms (102 meters), also off the coast of Florida, and D2761, in 818
