The lower jaw has the alveoles of the incisors and canines nearly vertical. The flange for protection of the tusk is long-, and rounded in front (Plate XIX, figure 1). This specimen represents a distinct sub-genns of Tinoceras, which may be called Laoceras. The type specimen (number 1044) of this species was found by Mr. S.

The geological horizon of this specimen is in the Dinoceras beds. The known remains of this species are preserved in the Museum of Yale College. Tinoceras Speiriaiiiim, Osborn, sp.

The restorations of this skidl do not allow some of its important features to be determined, but the generic characters ai-e distinct. In the restoration of this species, as given in the work cited above, the skull belonged to a male, and the lower jaw to a female. The bones of the fore limb, also, are in a position impossible in life. The type specimen of this species was discovered by Mr. Francis Speir, in 1878, in Wyoming. This specimen consists of the skull here figured. The geological horizon is in the Bridger beds of the Middle Eocene.
