Localit, ity.—1063, shell- bed, [селе Creek, Ngaruroro Riv 
Remarks.— Easily distinguished from A. huttoni (ботан) by its 
having en 3 spirals on the spire-whorls and 6 on the 
Ataxocerithium suteri n. sp. (Plate 17, fig. 2.) 
Shell of moderate size, heavy, subulate ; spire over 3 times height of 
aperture ; whorls flat, 9 remaining in holotype, apex broken in all cases, 
body-whorl rounded, not keeled, contracted quickly to short, straight 
neck; sculpture of 3 strong spirals, intersected by 15-17 somewhat broader 
below line of suture are 3 other moniliform spirals, anterior one wea 
below these are fine weak spiral threads on neck of canal; suture canali- 
eulated by spirals, sometimes with edge of fourth one showing; aperture 
broken in all cases, but apparently ovate, slightly channelled above, 
produced below into very short twisted oblique canal which runs along 
truncation of columella; columella straight, obliquely truncated below 
with well-developed median plait and obsolete anterior one boun 
truncation; inner lip with thick callus, which, however, does not always 
hide the strong basal spirals, giving the appearance of a fold or folds on 
parietal wall.
