Possibly a variety of P. chilinoides, from which it " only differs

" The markings are very variable, being sometimes oblique, 

 zigzag lines, extending over the whole surface of the whorls^

 whorl sometimes has two impressed transverse lines. The mouth 

 is nearly two-thirds the length of the shell."
