description
A shell that Petuch (1981) figured as an undescribed species of Heilprinia Grabau, 1904 from R / V John Elliott Pillsbury sta. P- 602 near Rosalind Bank northeast of Honduras in the Caribbean Sea is A. benjamini. However, station P- 602 was made with a 41 foot trawl in depths of 412 – 457 m at 20 ° 22.5 ' N, 87 ° 11.5 ' W, just east of Bahía de la Ascensión and south of Cozumel, México; only fish were recorded in the catch (Staiger 1968). Although that cruise ventured as far south as the Bay Islands of Honduras, it passed no closer than about 500 km to Rosalind Bank, so the locality seems suspect. Abbott (1974: 229) mistakenly classified Heilprinia (type species Fusus caloosaensis Heilprin, 1886, Pliocene, Florida) as a subgenus of Fusinus in which he included F. eucosmius, perhaps influencing Petuch (1981) and Okutani in Takeda and Okutani (1983) to associate A. benjamini with Heilprinia. However, resemblance between A. benjamini and Heilprinia is slight, and placements of the species there were unjustified.
discussion
Remarks. Aristofusus benjamini was mistaken for Fusus eucosmius Dall, 1889, even by Dall himself, who reported F. eucosmius from Blake sta. 290 off Barbados in 73 fm (134 m). That error was maintained by several authors (see synonymy) until it was resolved by Hadorn (1997). Aristofusus eucosmius [= A. excavatus (G. B. Sowerby II, 1880)] lives only in the Gulf of Mexico and the southeastern United States.
