Show 1879.] MR. E. A. SMITH ON MOLLUSCA FROM JAPAN. 217 upper ones with straight or even faintly concave outlines, pale upper margin, and of a uniform yellowish brown on the rest of th e surface ; suture deeply channelled ; last whorl large, longitudinally streaked with very fine and close white lines (only visible under a lens) ; columella covered with a thin pellucid callus, with three or four oblique plica? at the base ; basal callous band pale luteous, white at the upper edge, with a brown line just beneath, and bordered inferiorly by the uppermost of the basal oblique plica?, which is also brown ; edge of the canal brown. Length 6g millims., diam. 3 ; aperture 4 long. Hab. Station 14. The markings of these little shells, of which there are five, are rather indistinct to the naked eye. The longitudinal pale-brown lines are undulating, or partake of a zigzag disposition. They agree very well with Gould's brief description, and most likely are rightly assigned to his species, of which the Museum already possessed a single colourless example determined by Dr. P. P. Carpenter. 89. ANCILLARIA INORNATA. (Plate XX. fig. 56.) Shell elongate, acuminately ovate, white, faintly tinged with yellow above the sutural line : whorls 4, coated with a thin enamel; spire moderately acute at the apex, with slightly convex outlines ; last whorl indistinctly transversely striated with two narrow oblique sulci on the lower part, whereof the upper is the deeper and borders the basal balteus ; the extremity of the whorl deeply sulcated, with three or four oblique plicae between the sulcations. Aperture occupying rather more than half the whole length ; basal notch broad, shallow. Length 8 millims, diam. 3. Hab. Japan.
