Abé, 19 :
A small , peculiar species with four antapical spines ont the post-margin. Body is rotund posteriorly and pointed anteriorly. Its length is 1.3 trandiameter. The epitheca is subconical with an indistinct short apical horn. the apical pore has a short ventral slit with a small finger-like protuberance projecting on tis dorsal wall. The ventral precingular plates are the largest while the two dorso-lateral intercalaries are the smallest. The lateral apical plates are somewhat concave, forming the side walls of the apical horn. The girdle is comparatively wide and is deeply impressed with distinct side lists of the body wall. It is quite post-median, so that the epitheca exceeds the hypotheca, excluding the spines, the ratio of the altitudes of epitheca to hypotheca being 0.53. The furrow is slightly descending, and is displaced distally its half width without a marked proximal arch. The section at the girdle is flattened reniform. The hypotheca is somewhat polygonal in ventral view, four spines on each angle. The postcingular plates are low in altitude while the major part of the hypotheca is covered with two antapicals, the spines being on the latter. The central right spine is displaced dorsally while the rests are middle or slightly ventral, but the central left is the longest of the four though.
