Original Description of Struthiolaria armata by Marwick, 1924:
- " It has a high spire with very sloping shoulders and long strong spines on the shoulder-angle, 7 to 8 on the body-whorl and 6 on each of the spire-whorls. The suture is filled with a layer of callus which ascends to the tubercles above, while the inner-lip pad extends to about half-way between the tubercles and the suture, but does not quite bury the spines. The growth-lines are very strong, but there is no spiral ornamentation. "
