The radular structure of "Leptoxis compacta" is described as including a rachidian tooth with a widely convex basal margin and a blunt central cusp flanked by four to five denticles, with the outermost being weakly developed in most cases. The lateral tooth contains one larger rectangular central cusp that is flanked by four to five outer denticles and three to four inner denticles. The inner marginal teeth contain 10 to 12 denticles, and the outer marginal teeth have 12 to 16 denticles. The outer denticles are often weakly developed.
