Plate XIII, Fig. 3.
Shell small, inflated, thin, closely, minutely, concentrically ridged, with a green or olive-green epidermis; anterior end shorter; base evenly rounded, beaks full but not prominent; outline of the shell recalling Callista; anterior end evenly rounded, posterior produced, with a very obtuse rounded point, not rostrate; ligament under the beaks, but extending further behind than in front of them, wholly external to the tooth line, which is continuous below it; anterior teeth eight, posterior ten, with three or four undeveloped additional teeth under the beaks on each side; teeth prong-shaped; scars obscure, pallial line invisible; shell very thin, cardinal margin very weak and narrow. Maximum longitude 4.5; altitude 3.5; diameter 2.5; vertical of the beaks, 2 mm from the front margin.
HAB. – Stations 2781, 2782, 2783, and 2785, in 122 to 449 fathoms, mud, on the west coast of Patagonia; temperatures 47° to 50° F.
This species is exceptional for its thin shell and very green epidermis. I have not been able to distinguish any lunular area or escutcheon.”
