The animal in alcohol is dark red and measures 22 mm. in total length. The right shell-lobe of the mantle is orbiculate, with a thickened ridge curving from the posterior to the anterior edge. The left shell-lobe is reflected over about one fourth of the shell with a sharp thickened ridge extending backward along the left side from the anterior edge to that portion of the posterior edge which is nearly opposite the apex of the shell. There is a deep depression in the posterior portion of the dorsal surface of the foot to contain the shell. The tail is sharp above with a large mucous pore and ovei'hanging dorsal projection. The pedal line is very distinct and the sole of the foot shows clearly a well-defined central area. The radula (Fig. 1, M. C. Z. 32,540, slide, 1,623) is about mm. // /z Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Harvard University.
