Wikipedia
Holostei
Holostei is a group of ray-finned bony fish. It is divided into two major clades, the Halecomorphi, represented by a single living species, the bowfin (Amia calva), as well as the Ginglymodi, the sole living representatives being the gars (Lepisosteidae), represented by seven living species in two genera (Atractosteus, Lepisosteus). The earliest members of the clade appeared during the Early Triassic, over 250 million years ago.Holostei was thought to be regarded as paraphyletic. However, a recent study provided evidence that the Holostei are the closest living relates of the Teleostei, both within the Neopterygii. This was found from the morphology of the Holostei, for example presence of a paired vomer. Holosteans are closer to teleosts than are the chondrosteans, the other group intermediate between teleosts and cartilaginous fish, which are regarded as (at the nearest) a sister group to the Neopterigii. The spiracles of holosteans are reduced to vestigial remnants and the bones are lightly ossified. The thick ganoid scales of the gars are more primitive than those of the bowfin.

Holostei
Holostei are bony fish that show primitive characteristics. There are eight species divided among two orders, the Amiiformes represented by a single living species, the bowfin, and the Lepisosteiformes, the gars. There are more species to be found in the fossil record. Holostei share with other primitive fishes a mixture of characteristics of teleosts and sharks. In comparison with the other group of primitive fishes, the chondrosteans, the Holostei are closer to the teleosts and further from sharks: the pair of spiracle found in sharks and chondrosteans is reduced to a remnant structure; the skeleton is ossified. In gars, the tail is still heterocercal but less so than in the chondrosteans; bowfins have many rayed dorsal fins and can breathe air like the bichirs. The gars have thick ganoid scales typical of sturgeons whereas the bowfin has thin bony scales like the teleosts. The gars are therefore in this regard considered more primitive than the bowfin. The Holostei is often regared as paraphyletic; as a result this infraclass is often not used, the two orders contained in it being often treated simply as members of the sub-class Neopterygii without any taxonomic association. However, recent work mitochondrial analysis of DNA seems to support its recognition, so the question is not yet resolved. Nearly all living bony fishes are teleosts.
