C. 8060. Atlas vertobni associatt'd with tlio type skull. Tn this specimen the lateral surfaces for 
the axis are roughly triangular, their inner sides hounding the hroad notch for the 
odontoid being straight and nearly vertical. Condylar cups hroad and deeply concave, 
extending up to the level'of the neural arch and down to the ventral bar.
