Text Appearing Before Image:
int; the sides of the plate facetted and marked with fine ridges parallel to the outer border. Form. $ Loc. Middle Devonian : Eifel. 36160. Imperfect large horn-like plate, showing the superficial ribbed ornament above, and the inner cancellated tissue towards its base ; Gerolstein, Purchased. 1861, 234 DIPNOI. Subclass IV. DIPNOI. Skeleton partially ossified, with numerous well-developed mem-brane bones. Upper mandibular arch confluent with the chondro-cranium ; gill-clefts feebly separated, opening into a cavity with external cover. Exoskeleton consisting of true bony tissue. In the living forms—optic nerves not decussating, bulbus arteriosus of the heart with series of valves, intestine with a spiral valve, and air-bladder lung-like. The dermal or membrane bones of the cranial roof in this subclass exhibit little conformity with the arrangement almost invariably observed in the Teleostomi; and it seems impossible to apply to them the nomenclature adopted in the case of the latter subclass.
