Close as this stands to the next species it may readily be recognized by 

 the subulate point, composed apparently of the excurrent nerve, but which, 

 after treatment with caustic alkali, will be seen to have a border of a single 

 row of cells, which observed in the dry state by reflected light stand out as 

 papillae.
