History and Synonymy

Canarium wilsonorum (Abbott, 1967: 455) (Strombus (Canarium) wilsoni) [incorrect original spelling, see Kronenberg & Dekker, 2000]

  • Strombus erythrinus erythrinus Abbott, 1960 [in part]
  • Strombus species cf. urceus Weaver, 1965: 100, pl. 25 bottom row centre figs.

1995

Cook, 1995, p. 1:

  • "After checking the Bishop Museum collection, I found that they have no Strombus labiatus from Hawai."
  • "There were also no Hawaiian Strombus erythrinus in the Bishop Museum collection."

Cook, 1995, p. 5:

  • "I can find no record of a living Strombus erythrinus found in Hawaii. Cliff Weaver in his Hawaiian Marine Mollusks, May 1965, stated: "Although the range of Strombus erythrinus erythrinus Dillwyn, 1817 was reported as extending to Hawaii (Abbott, 1960), that record was based on a single subfossil specimen dredged at Pokai Bay, Oahu and therefore is not included in this report on living species. A true fossil erythrinus collected by Dr. C.M. Burgess in a limestone formation at Kahi Park, Nanakuli, Oahu establishes this species in Hawaii's Pleistocene." (figure 4) After considerable research, I am convinced that the Burgess shell dredged by the R/V Pele in 1959 (figure 2) is not a crabbed "Strombus erythrinus" (or a subfossil "S. erythrinus") but is Strombus wilsoni Abbott, 1967. I am convinced that the fossil (figure 4) is also Strombus wilsoni and that Strombus erythrinus has never been found in Hawaii."

Cook, 1995, p. 6:

  • "Strombus wilsoni is still a rarely collected Hawaiian shell but it is an established species. We and others have found a few live-collected shells at 50 to 70 feet as well as numerous fresh-dead specimens."

2000

Kronenberg & Dekker, 2000, p. 5:

  • "Abbott (1967: 455) described Strombus (Canarium) wilsoni as new to science (type locality: Zanzibar; also recorded from Western Australia and Fiji). The epithet wilsoni was used by subsequent authors (e.g. Walls, 1980: 109-110; Kronenberg & Berkhout, 1984: 338, caption of pl.7 fig. 12; Wilson, 1993: 156, caption of pl.21 fig. 7; Drivas & Jay, 1998:15; Kreipl & Poppe, 1999: 37; Poppe, Man in't Veld & De Turck: caption of plate 67 [specimen nr. 7 is not this species], Poppe & Groh, 1999: 60). Yet in his dedication, Abbott (1967: 455) stated: "This species is named after the Australian malacologist, Dr. Barry Wilson, and also after Mr. Wilson Darwin of Philadelphia.". From this dedication it is evident that this taxon was named after two persons, which implies that the specific epithet has an incorrect original spelling (ICZN Art 31.1.2). Inevitably, the original spelling of the epithet has to be emended into wilsonorum (ICZN Art. 32.5.1), with the emended name retaining the original authorship and date, viz. Strombus wilsonorum Abbott, 1967."

Reports

Jeanette & Scott Johnson about Canarium wilsonorum from Kwajalein Atoll:

  • "Canarium wilsonorum is a species with a couple of distinct growth forms in the Marshall Islands that live in different habitats. Specimens from the rubble and under rocks on seaward reef in 10 to 25m of water are small, short, and rather squat. The larger population that lives shallow lagoon Halimeda beds have shells that tend to be much larger, narrow, and elongate. Although the larger seaward reef specimens may match the smaller lagoon specimens in length, those from the lagoon seem distinctly narrower and more elongate. It almost seems as though we are looking at two different species. Both forms are highly variable in color."

"The specimen came from the seaward reef. The rest are from lagoon Halimeda patches."

  • bottom left: "A hermit crab has taken over the yellow shell below."
  • br: "A tiny shell in some stringy algae."
