NuDiLiMACES Latrellle, 1824 [November]
Reference: Annales des Sciences Naturelles,
3: 327, and table between pp. 334-335

"Nulimaces" (vernacular). Latinized by Latreille
(1 825: 1 78). Established as a family and
not available as such (not based on a genus).
Nyctilochidae Dall, 1912 [September]
Reference: The Nautilus, 26(5): 59
Type genus: /\/ycf/7oc/?as Gistel, 1848
Remarks: When Dall established Nyctilochidae,
he considered Nyctilochus to be typified by
Murex tritonis Linné, 1 758 [i.e. Charonia] and
he meant to replace Tritonidae / Tritoniidae
with Nyctilochidae. However, Beu (1970: 206)
demonstrated that Murex tritonis was not one
of the originally included species, and designated
Triton tigrinum Broderip, 1833, as type
species; Nyctilochus is then a subjective synonym
of Cymatium. This is an Art. 41 situa-
tion, but Charonia and Cymatium are currently
considered consubfamilial, so that the problem
has a purely academic interest.
