The radula of P. damonz (Fig. 57, on page 300) is quite small (about 
2mm. long and 0.4 mm. wide in a specimen 30 mm. long). The central 
tooth is small, with long denticles, the body slightly swollen below the 
cusp, its posterior margin indistinct in our preparation. The laterals 
have the usual rhombic body and an extremely long peduncle. The 
marginals are also very long. The formula of denticles is: C. 4, 1, 5 or 
4,1, 4; Li. 3,1,8: M. 7 and 7.
