Original Description of Aporrhais triangulata by Gardner, 1884:

• "This species differs from the last chiefly in its smaller size, the largest measuring but 16 mm. in length by 15 across the wing. It is a reduced almost facsimile of the last, except that the striae are more distinct and the third or inferior keel on the body-whorl is less pronounced. It is rather more obtuse and relatively shorter, and the wing more triangular or shoulder-of-mutton-shaped than in A. Sowerbii, which it agrees best in size."
