Paradmete fragillima (R. B. Watson 1882)

“VOLUTOMITRA FRAGILLIMA, n. sp.

St. 149 d. Jan. 20, 1874. Lat. 49° 28' S., long. 70° 13 E. Royal Sound, Kerguelen. 28 fms, Mud.

Shell.—Ovate-ventricose, thin, smooth, with a short spire, a long base, a large oblong mouth, and 4 teeth on the pillar. Sculpture. Longitudinals—there are many fine hair-like lines of growth. Spirals—there are very many broadish, but obsolete, rounded threads; the front of the snout is obliquely crossed by about 15 stronger and more regular threads. Colour subpellucid white under a very thin yellowish smooth epidermis. Spire short and broad. Apex bluntly mamillate, not elevated, but rising a little on one side. Whorls nearly 6, convex, rounded above, sloping below. Suture a little impressed and strongly marked. Mouth oblong, somewhat oblique, rather large, pointed above, prolonged into a longish, open, truncated, but not emarginated canal. Outer lip thin, sharp, regularly curved, quite straight above, where it is slightly and widely hollowed back on the edge, prominent and patulous below, a little pinched in at the canal. Inner lip scarcely convex above, and very little concave at the base of the pillar, which is somewhat oblique and direct; there are four oblique, rather strong teeth, of which the two in the middle are the strong­est; a very thin, narrow, definite-edged glaze extends down the edge of the mouth. H. 0.57. B. 0.3. Penultimate whorl, height 0.1. Mouth, height 0.39, breadth 0.12.

Without the animal it is, of course, not easy to distinguish between this form and Admete, but the apex is larger and the pillar-teeth stronger than they are in that genus. The generic features are well marked in this species, which, however, resembles no other known to me.”
