J. B. Knight 1930The subgenus Hyphantozyga is erected to embrace such Hemizygae as have progressed much further along the lines of the weakening d the transverse costae and strengthening of the revolving lirae. The transverse and the revolving ribs are in this group subequal at all post-nuclear stages of development and cover the base as well as the sides of the whorls. This appearance of a coarsely woven cloth given by the two sets of ribs running at approximately right angles to one another has suggested the name of the subgenus which is derived from the Greek 6$av~os (woven) and the syllable -zyga. Too few specimens are at hand to allow the preparation of sections. The nucleus, which has been seen, is entirely characteristic of the Pseudozygopleurinae.
