Treatment

Hedronchus sternbergii , gen. et sp. nov.

Char.Gen.-The bone on which this genus reposes has the appearance of the crown of a young tooth. Its central cavity is large anid expands to the margin of the basis; its apex is unworni. It appears to be too protuberant for the position of a dermnaltubercle. It may be dlistinguiished as a short crown on a shorter slightly constricted portion or neck. The crown culminates in three crests, wlichl together form a letter T, and which descend towards the neck. There is no investment of einamel or cement, and the material of whiclh it is composed resembles dense bone.

Char. Specif. - The faces on each side of the stem of the T, are conicave anid divided by an oblique crest, whichi descencls fromnthe common apex. The other face is gently convex, and the iniferior part of each of its bounding crests projects ear-like. Tile base is an oval.
