COVER
Globigerina bulloides (d’Orbigny), Recent, from 200-meter depth on the
Scotian Shelf. Details of spinal development on the ultimate chamber
adjoining the apertural opening of the
shell (x 3500). The new scanning
electron microscope ranges in magni-
fication from x 5O to greater than
x 100,000. See page 1318. [G. A.
