Philippi has quoted in the text fig. 6 for this variety, but it evidently is fig. 1 1 that 

 agrees with the description, fig. 10 is his variety sutziralis, quoted as fig. 7. The figs 6 — 9 of 

 that author represent his L. intermedia, considered by many authors to be merely a variety, 

 it is often not an easy task to distinguish it from younger specimens of L. scabra. It seems 

 that Tryon (I.e. p. 244, PI. 42, fig. 2 1 — 24) has mixed the two species, for his character 

 "periphery angulated or carinated", is in contradiction with Philippi's original description, the 

 figures 22 and 24 are probably young specimens of scabra.
