Shell elong-ate-conic, subturrited, milk-white. Nuclear whorls two, 

 .siiijill, well rounded, ol)liquely about one-half inimer.sed in the first 

 ])ost-nuclear whorl. Post-nuclear whorls rather high between the 

 sutures, inflated, well rounded, shouldered, marked by irreg-ular lines 

 of growth which lend the surface a somewhat luieven appearance and 

 many tine, closely-placed wavy spiral striations; sutures strongly 

 marked. Peripher}^ of the last whorl with a faint suggestion of an 

 angulation. Base prolonged, g"ently rounded, marked like the spaces 

 between the sutures. Aperture elongate-ovate, posterior angle obtuse, 

 somewhat effuse at the junction of the lip and columella; outer lip thin 

 without internal lirations; columella short, curved, with a very strong, 

 acute, obli([ue fold near its insertion which fuses directly and is con- 

 tinuous with the anterior reflected portion of the columella; parietal 

 wall covered by a very thin callus. 



The specimen described was received from Hilgendorf and comes 

 from Japan. It has ten post-nuclear whorls and measures: long. 13.7 

 mm.; diam. 4.4 mm. There are two other individuals among the Ber- 

 lin matei'ial, both young specimens and both from Japan. P. [A.) 

 vin/o A. Adams is the t.ype of Ac/at /ur, we do not know why Adams 

 changed this to Myonia and Amathis as we have been unable to find 

 the name preoccupied.

Shell large, elongate-conic, milk-white. Nuclear whorls three, large, 

 helicoid, moderately elevated, having their axis at a right angle to the 

 axis of the later whorls and scared}' at all immersed in the first of them. 

 Post-nuclear whorls well rounded, the greatest convexity falling a 

 little anterior to the middle between sutures, moderately shouldered, 

 and ornamented by strong, rounded, oblique, flexuose axial ribs, Avhich 

 are somewhat fused at the summit and more so at the periphery. 

 Intercostal spaces rounded, not quite as wide as the ribs, decidedly 

 depressed, terminating suddenly at the periphery. Fourteen axial 

 ribs are present upon the first, eighteen upon the fifth, twent}' upon 

 the tenth, and twenty-four upon the penultimate whorl. Suture chan- 

 neled, periphery somewhat angulate, the summits of succeeding- whorls
