CYLINDRELLIDAETryon, 1868 [2 April]
Reference: American Journal of Conchology,
3(4): 311
Type genus: Cylindrella L. Pfeiffer, 1840
Remarks: Cylindrella Pfeiffer, 1840 has generally
been regarded as a junior homonym
of Cylindrella Swainson, 1840 [May] (and
Distaectria Cossmann, 1891 was proposed
as a replacement name), and on this ground
Cylindrellidae has been treated as an invalid
name. However Cylindrella Swainson has
been suppressed for the purpose of the Law
of Homonymy by Opinion 1 030 (1 974: 1 90).
This leaves Cylindrella Pfeiffer and Cylindrellidae
available names. See also Urocoptidae
and Brachypodellinae.
