Extract

Zoœcia separated by a distinct furrow, which passes into a deep crevice at the junction points, widely rounded below but tapering very considerably and almost to a point above, with areas of the same shape and upright rounded side walls thickening considerably below, and often developing something of an internal front wall; average length of area 28 mm., breadth 2 mm., but marginal zoœcia often run much larger.
