This species originally described by d'Orbigny from the shore 

 sands of Cuba is apparently found in the Gulf of Mexico and farther 

 northward along our eastern coast. This and the following smooth 

 species of Bulimina are not in a satisfactory state, and it should be 

 determined by a study of abundant specimens as to whether they are 

 very variable or whether there are numerous species which with 

 close study can be distinguished.

Description. — Test elongate, tapering, somewhat fusiform; cham- 

 bers increasing in size and height as added, somewhat irregular, 

 chambers comparatively few, distinct, irregularly spiral; sutures 

 distinct, depressed, wall smooth, finely punctate; aperture ovate, 

 small; color white. 



Distribution. — Most of the Atlantic records for this species are about 

 the British Isles. There are no specimens in the Albatross material 

 which seem to be referable to this species.
