One specimen of this very remarkable and beautiful shell was preserved in spirit. Animal pale-coloured, like that of D. hugonis ; the mucous gland has a very small overhanging lobe and a broad pallial margin. The odontophore (Plate V. fig. 4 b) has the central tooth tricuspid, the central cusp hardly rising above those on either side; the median are square at the end, bicuspid, the laterals (fig. 4 c, 80th and 81st) have a sharp inner cusp and a rounded outer cusp, rising close together ; the outermost laterals are unicuspid and small: + 70 . 14 . 1 . 14 . 70 + + 80 . 1 .80 +. Some of the small outermost teeth were lost in dissection. The generative organs (figs. 4 and 4 a) are similar to those of D. hugonis and do not require any further description. |
