hypotypes 33347-33348, UCMP), Sachet (1962c), Salvat & Ehrhardt
(1970); as Cyclopecten zacae in Emerson (1994); Grau (1959) states
Clipperton specimens are D. vitreus and not D. zacae; Keen, 1971.
Delectopecten gelatinosus (Mabille & Rochebrune, 1889) is
synonymous with D. vitreus in Grau (1959) and considered to be the
deep-water species living at Clipperton, fide Tomas Waller, USNM
(pers. comm., 1998); KLK 201317-201321(voucher), 201324 (with
host). Remarks: Trawled from 113 m in 1998, attached by byssus to
brown hydroid sp. Many specimens collected live and several
preserved with host in KLK wet collection.
As S. gloriosus Dall, Bartsch & Rehder, 1938, in Hertlein & Allison
(1966) (live) (empty shells in sediment deposits in lagoon), Salvat &
Ehrhardt (1970) (4 valves, 2 fresh), Keen (1971), Emerson (1978);
synonymized in Kay (1979); Bernard, 1983; Bernard et al., 1991;
Emerson, 1994; as Spondylus sp. in Small (1994, 1995); Skoglund
(2000); Kaiser & Bryce, 2001; as cf. linguaefelis in Schneider (2004)
(worn beach deposit); SBMNH 358706-358707 (live, wet collection),
358544; MNHN; KLK 201325 (juv.), 201414-201415 (voucher),
201423 (+). Remarks: Collected in 1994, 1998, 2005 and 2007. One
or more specimens found live and preserved in KLK wet collection.
Numerous fragile lagoon deposits.
Hertlein & Emerson, 1953 (?valves, dredged, 100-200 fm); Sachet,
1962c; Salvat & Ehrhardt, 1970 [also listed as erroneous, p. 223];
Bernard, 1983; Bernard et al., 1991; Emerson, 1994, 1995. Remarks:
Not collected since 1952 although no deep-water dredging for mollusks
at those depths has been done since then.
HETERODONTA
Hertlein & Allison, 1966 (beach deposits, in sediment deposits in
lagoon); Salvat & Ehrhardt, 1970 (valves); Bernard, 1983; Bernard et
al., 1991; Emerson, 1994, 1995; KLK 210019 (voucher), 210401-
210405. Remarks: Two beach deposits collected in 2005 and common
as sediment deposits in lagoon. This species has not been recorded
alive at Clipperton.
As C. thaanumi in Hertlein & Allison (1966) (empty shells in
sediment deposits in lagoon), Salvat & Ehrhardt (1970) (empty shells
in sediment deposits in lagoon), Emerson (1978); Bernard, 1983;
Bernard et al., 1991; Emerson, 1994; KLK 210018 (voucher), 210406-
210407. Remarks: Collected in 2005 and 2007 as fragile empty shells.
This Indo-Pacific species has only been recovered from sediment
deposits in the lagoon, obviously thriving there before the closure of
the lagoon and, in turn, the brackish water. No specimens have been
collected from the ocean side of the atoll.
SBMNH 210427; MNHN; KLK 201332 (voucher), 210039 (+).
Remarks: Collected in 1994, 1998, 2005 and 2007. One or more
specimens found live and preserved in KLK wet collection. This
species is quite common at Clipperton.
