-
[BUCCINUM MULTIRUGATUM] Shell thick, ovate; spire composed of five whirls, marked with deep impressed revolving lines; apex rather obtuse; columella, with a strong fold at base and a slight prominence at the base of the body whirl; bicarinate, aperture greater than half the length of the shell.
-
(A.) [Mossosaurus Rectus tooth] Tooth long, pointed, compressed; nearly equally divided on the outer and inner faces; the faces are formed by five equal and similar planes, bounded by angular ridges, only two of which, on each face, can be said to approach the apex; these are the two anterior and two posterior ridges curved backwards; bicarinate; but the posterior edge is nearly straight, while it has a convexity before which gives an apparent curvature which does not exist; edges smooth; enamel is probably thin or removed, leaving a dense dentine, with fine longitudinal cracks which appear at first like fine striae.
