Current status.
Valid.
Remarks.
Material designated as the “
type
” of
Egmundella grandis
by
Fraser (1941b)
is at the NMNH (USNM 43455). That collection comprised
syntypes
, with material in ethanol and on four slides. The best of these specimens, growing on a bivalve shell and returned to the original vial (USNM 43455), is designated here as the
lectotype
. All others in the
type
series are
paralectotypes
(USNM 1458863). The four slides forming part of this series are relatively recent preparations and were not made by Fraser.
While the location of this collection was given by
Fraser (1941b)
as the state of
Maryland
, coordinates reveal instead that the specimens were from the continental slope off the eastern shore of
Virginia
.
On the basis of morphology, biogeography, and habitat, a report of
E. grandis
from shallow waters of
Belize
(
Spracklin 1982
), in the Caribbean Sea, is considered by us to be a misidentification.
No
other records exist of this obscure and briefly described species, known only from its trophosome. Regarded as valid here, it is not listed in WoRMS. The species was excluded from the lists of
Cairns
et al
. (1991
,
2002
) earlier because its depth (
288 m
) was below the
200 m
bathymetric limit set in those two works.
