==Description==
Like other members of the ''[Spectamen](/source/Spectamen)'' genus, ''S. geruloides'' has spiral cord patterns on its [shell](/source/Seashell). It is characterized by broadly rounded cords, intervals with multiple spiral lirae, and weak growth lines, and can be distinguished from the similar ''[S. gerula](/source/Spectamen_gerula)'' by its smaller [protoconch](/source/protoconch) and greater number of spiral lirae. It can vary in color, but adult shells are typically yellowish-white with axial stripes in shades of brown. Protoconchs are yellowish-white at the apex and otherwise yellowish-brown, while juvenile shells are entirely yellowish-brown. As of 1987, the largest known specimen had a length of 7.7 mm and a diameter of 8.1 mm.[{{Cite web |last=Herbert |first=D.
