Description. — 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, initial end rather sharply pointed, 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. 



Distrihution. — Type-specimen from the Tortugas, Florida (J. A. C. 

 Coll.). Typical specimens from. Albatross station D2641, in 60 fathoms 

 (110 meters), off the southeast coast of Florida, near Carysfort Light. 

 There are also numerous specimens from a number of stations as far 

 north as the coast of South Carolina and in the Gulf of Mexico. 

 Flint's record for T. transversaria is this same type station, and his 

 specimens which I have examined agree with this closely. Another 

 slide in the U.S.N.M. collection from this station is labeled by Flint 

 T. sagittula, var. fistulosa. The only Atlantic Cliallenger station 

 referred to this later name is No. 33, off Bermuda. The species then 

 has a very definite range, similar to that of many of the species in 

 the Gulf of Mexico and adjacent waters. It is near T. sagittula, var. 

 fistulosa H. B. Brady, which is common in tropical and subtropical 

 waters in the Indo-Pacific. The test is much smoother, the sutures 

 less distinct, the apical end more pointed, and a comparison of speci- 

 mens from the two regions show that the two are evidently distinct.
