ed and transversely articulated with red and purple olive" OH a 

 polished flesh-colored, cream or white ground. Alt. 50-100 mill. 



Tn mania; South Australia. 



The synonyms are Buccinum tritonis, etc., Chemnitz, P. tritonis, 

 Auct., P. bulimoides and P. varia Lam., P. picta DeBlain, P. leli- 

 manni and P. preissi Mke., P. decorata Chenu. 



Specimens are frequently found exceeding the dimensions given 

 above. The color pattern is extremely variable, as is shown by the 

 figures. There is one form which is omitted in my illustrations ; it 

 is of a pinkish-cream color, with rather distant, narrow, spiral white 

 and deep red articulations. The form is either very elongated, or 

 rather short ; it is always, however, longer and with much less convex 

 whorls than P. ventricosa.
