Such specimens are often very numerous in parts of the general 

 West Indian region, and have already been noted under Planorbulina 

 acervalis.

 times arranged in more or less radial rows; apertures formed by the 

 coarse pores of the wall.

Typical species occur in the Indo-Pacific at the present time, but 

 were widely distributed and of large size in the Tertiary.

The above records are Atlantic ones for this species. I have found 

 very few specimens in the Albatross and other material from the 

 western Atlantic. The following notes are from Heron- Allen and 

 Earland in regard to their Clare Island material from the coast of 

 Ireland. 



"This species occurs at a great many stations (20 at least), both 

 in shoresands and dredgings, and in such variety as to present great 

 difficulties in its identification as between G. vesicularis and G. globulus. 

 Brady, in his 'Challenger' Report (FC), has referred to the confusion 

 w^hich exists between these two types. It seems questionable whether
