Description. — Test composed of numerous inflated chambers in a 

 trochoid spiral, rather rapidly increasing in size as added; wall 

 smooth, finely punctate; sutures depressed; aperture consisting of 

 a series of rounded elliptical openings at the junction of the chambers 

 along the sutures. 



Diameter usually less than 1 mm. 



Distribution. — The map of distribution of the Albatross specimens 

 is an interesting one. The largest number of stations are from the 

 "Caribbean and also by far the largest number of specimens are from 

 this same region. Specimens occur at the stations south of the 

 Equator in tropical waters of the coast of Brazil. There are also 

 a very few specimens from scattered stations along the Florida 

 coast and northward as far as the Carolina coast, but no specimens 

 have been noted northward from Cape Hatteras. 



The species was originally described by D'Orbigny from shore 

 sands of Cuba and it is probably found in such conditions throughout 

 the West Indies, for it is a pelagic species. The adaptation of the 

 nearly spherical form and instead of one large aperture the large 

 number of elliptical openings along the sutures allowing free access 

 of the protoplasmic contents to the exterior are both for pelagic 

 conditions. 



There are numerous records for this species from other parts of the 

 world, but the general West Indian region seems to be its typical 

 habitat.
