Description
Solitary, small, conical, calice deep, septa joining axially to form a strong twisted pseudocolumella, with remote "dissepiments," and tabulae. [In the only illustrations of what is probably type material, by NICHOLSON & ETHERIDGE (l878b), the transverse section resembles that of Stereolasma rectllm (HALL) except that the cardinal fossula does not invade the columellar mass; in this respect it resembles Syringaxon LINDSTROM, 1882b. Presence of an aulos is unproven; the longitudinal section, with its slightly oblique calical floor sloping downward toward the concave side of corallum, and absence of calical projection of columellar mass, differs from that used by SIMPSON (1900, p. 207) as S. rectllm, in which an oblique calical floor, without calicular projection, slopes down toward convex side. SIMPSON'S longitudinal section seems, however, somewhat inconsistent morphologically with his transverse section. Until the type material is restudied, Lindstroemia NICHOLSON & THOMSON will remain unsuitable as the name genus for a family.]
