Distribution. — This species described from the Clare Island region 

 is also recorded by the authors from off South Cornwall and from 

 nine stations west of Scotland, although they remark as follows on 

 this last material: " Poorly represented, the specimens being few, and 

 not very typical." I have seen no specimens in the western Atlantic 

 which can be referred to this.

As will be seen by the above references, B. laevigata has been 

 recorded from various places off the British Isles. As far as I have 

 seen the species does not occur in the western Atlantic.

Description. — Test elongate, much compressed, gradually tapering 

 to the rather bluntly rounded apical end, often somewhat twisted,

 which are slightly rounded; chambers usually about as high as wide, 

 slightly tumid, the sutures very distinct, irregularly curved, limbate; 

 especially along the median portion of the face; wall calcareous, 

 smooth, punctate; aperture elongate-oval, in some specimens some- 

 what remote from the border and terminal; color white.
