“…Thus, it is present in the embryo of Neoceratodus (Fox 1965); in several Actinoperygians (DE BEER 1924, GOODRICH 1930, HOLMGREN 1943, BERTMAR 1965, and is also retained in the adult Teleost, where it runs immediately behind the pituitary, collecting blood vessels from it (FOLLENIUS 1965).…”

“…The head vein is expanded in the orbit to form a large orbital sinus (sinus orbitalis), which fills the part of the orbit not occupied by the eye and its accessory structures. The two orbital sinuses are connected by the large irderorbital vein (v. interorbitalis), often called hypophysial or pituitary vein (GOODRICH 1930, DE BEER 1924, BERTMAR 1965, certainly homologous with the v. retrohypophysea of Amniotes (SHINDO 1915, ENEMAR 1960. The interorbital vein runs in the cranial base in the posterior wall of the pituitary fossa.…”

“…This branchiostegal cartilage is present in all Callichthyidae examined. In the antero-dorsal surface of the anterior ceratohyal there is a small foramen for the passage of the afferent mandibulary artery (Bertmar, 1962;Nelson, 1967). The junction between the anterior ceratohyal and the hypohyal is synchondral only.…”

Based mainly on morphological characters, the phylogenetic relationships among genera and some species groups of the neotropical family Callichthyidae were examined. A study of the osteology of a generalized callichthyid, Callichthys callichthys (Linnaeus), with detailed comparisons among representatives of the remaining genera in the family, is presented and used as a basis for the phylogenetic analysis. A single most parsimonious tree supported the monophyly of the family Callichthyidae based on 28 derived features and the division of the family in the subfamilies Corydoradinae and Callichthyinae. In the subfamily Corydoradinae, the genus Aspidoras is the sister-group of the clade formed by Colydoras plus Brochis. Five derived features support the monophyly of this clade and four support the monophyly of Brochis. No characters, however, were found to support the genus Colydoras. In the subfamily Callichthyinae, &anma and Hoplosternum are sister-taxa. Megalechis represents the sister-group of Dianema plus Hoplostmum and Lepthoplosternum represents the sister-group to Megalechis plus Dianema plus Hoplostmum. Finally, Callichthys is considered the least derived member of the subfamily, and is hypothesized as the sister-group of the remaining species. A key to all callichthyid genera is provided.

“…Lateral coronary trunks are also present in the living Dipnoi (Foxon, 1950). Bertmar (1962) described the development of the hypobranchial arteries in the characid Hepsetus odoe and he found that the short midventral hypobranchial artery arises from the fusion of two lateral vessels. For support of his viewpoint (lateral hypobranchial arteries as primitive in relation to a single midventral vessel) he cites the description by Allis (1911Allis ( , 1912 of lateral hypobranchial arteries in the primitive actinopterygians Polyodon and Amia.…”

Coronary artery anatomy was studied in 16 shark species belonging to 9 families of the orders Hexanchiformes, Squaliformes, and Carcharhiniformes. The study included 101 specimens and used an injection-corrosion technique that obtained internal casts of the main trunks and coronary arterial branches. The results showed 2 main patterns of coronary arterial arrangement: the dorsoventral coronary trunk pattern, shared by lamnoid and advanced carcharhinoid sharks, and the lateral coronary trunk pattern, shown by hexanchoid and squaloid sharks. Scyliorhinus and Galeus had intermediate arrangements of their vessels.
