PoNTOHEDYLiDAE Starobogatov, 1983 [after 22
February]
Reference: Vsesoiuznoe soveshchanie po
izucheniiu molliuskov, 7:31
Type genus: Pontohedyle Golikov & Starobogatov,
1972
Remarks: Introduced, in violation of Art. 40.1
as a replacement name for Mancohedylidae,
based on Mancohedyle Rankin, 1979 [not
available from Salvini-Plawen, 1973: 125],
which Starobogatov regarded as a synonym
oi Pontohedyle. Both names have had limited
usage and Mancohedylidae is the valid
name under the Principle of Priority.

PoRCELLANiDAE Roberts, 1870 [3 February]
Reference: American Journal ofConchology,
5(3[appendix]): 189
Type genus: Porcellana da Costa, 1776
Remarks: Roberts used Porcellana for
Cypraea, therefore in a sense different from
that of Gray, 1853. Porcellanidae Roberts,
1870, and Porcellaninae Gray, 1853, are
therefore homonyms but not synonyms. Por-
cellana da Costa, 1776, was established in
synonymy (of Cypraea) but used as valid
before 1961 (e.g., by Roberts, 1870 [attributed
to Rumphius]; Jousseaume, 1884: 91 [at-
tributed to Klein]), and is therefore available
under Art. 11.6.1. Porce//a/?a da Costa, 1776,
is a senior homonym of Porcellana Lamarck,
1801 [Crustacea]; however, under Art. 23.9
of the Code, Porcellana da Costa, 1776, is
here declared a nomen oblitum and Porcel-
lana Lamarck, 1801, a nomen protectum,
based on usage in at least the following publications:
