Original description.
The
shape

surface
is marked by 3 nodulous cords on each whorl, and there are 3 basal cords. The
colour
is white, and glistening; and the
size
5
x
1.6 mm
.
Characteristics.
It is near 869, whitechurchi, but more broadly conic, and much smaller.
Diagnosis.
The available specimen is
4.7 mm
high, but subadult. Conical shell with flat sides. Teleoconch of eight whorls with three spiral cords clearly visible since the first whorl and with nodules at the intersection with the slightly prosocline axial ribs. Peristome not preserved and the specimen is subadult, thus without base. Apex badly worn, but apparently paucispiral of 1.5 whorls which bears three smooth spiral cords on after the first half whorl. White shell with small brown marks.
