Family HALOSAURIDAE Halosaurs
4 genera/subgenera • 16 species

Aldrovandia Goode & Bean 1896    ia, belonging to: Ulysses Aldrovandus (1522-1605), of Bologna, “founder of the first natural history museum, whose name, strangely enough, has never been honored by association with a genus of animals or plants”

Aldrovandia affinis (Günther 1877)    related, referring to the “greatest similarity” between this species and A. rostrata and Halosaurus ovenii

Aldrovandia gracilis Goode & Bean 1896    slender, described as a “very slender species”

Aldrovandia mediorostris (Günther 1887)    etymology not explained, either medius, middle, or mediocris, middling; rostris, snout, perhaps referring to “comparatively short snout”

Halosauropsis Collett 1896    opsis, appearance, i.e., similar to Halosaurus but with differently shaped light organs on head and lateral line (disputed by Samuel Garman, who suggested that Collett may have examined damaged specimens), but genus clearly differs from Halosaurus in lacking scales on top of head between eyes and nostrils       

Halosauropsis macrochir (Günther 1878)    macro-, long; cheiros, hand, referring to long pectoral fin, which extends nearly to the “root of the ventral”

Halosaurus ovenii Johnson 1864    in honor of Richard Owen (1804-1864), Superintendent of the Natural History Departments of the British Museum, “whose investigations in regard to the skeletons of fishes are not the least valuable part of his many contributions to zoological science” [name latinized with “v” instead of “w”]

Halosaurus pectoralis McCulloch 1926    referring to its very long pectoral fins, which distinguishes it from most congeners

Halosaurus radiatus Garman 1899    rayed, referring to numerous branchiostegal rays, which “serve to distinguish this species from any other at present known”

Halosaurus ridgwayi (Fowler 1934)    in honor of the late Robert Ridgway (1850-1929), “with pleasant memories of by gone days in his department of ornithology in the Smithsonian Institution”

Subgenus Halosaurichthys Alcock 1889    halos, sea; saurus, lizard; ichthys, fish, literally “sea lizard fish,” alluding to lizard-like shape and affinity with Halosaurus

Notacanthus bonaparte Risso 1840    patronym not identified but probably in honor of Charles Lucien Bonaparte (1803-1857), who named a barracudina (Arctozenus risso) in honor of Risso the same year

Notacanthus chemnitzii Bloch 1788    in honor of garrison preacher (and conchologist) Johann Hieronimus Chemnitz (1730-1778) of Copenhagen, who supplied Bloch with North Atlantic and Arctic fishes, including type of this one
