Thin, very large and richly colored, the sculpture com- 

 posed more of continuous ribs, often forked above and be- 

 low, than of warts. The last whorl measures 44 mm. high 

 behind, is smooth, streaked with brown-red, the streaks not 

 confluent on the base. The columella has only a thin, trans- 

 lucent deposit. Throat livid blue-red, the thin, expanded 

 peristome brownish and only quite lightly thickened within. 

 The columella is not truncate as in typical doivnesi, but 

 tapers obliquely. A second specimen also in the Berlin 

 museum is thicker, with thicker peristome, more obese, and 

 measures 95 x 46 mm., but otherwise is quite similar. Length 

 95, diam. 44 mm.

D'Ailly regards this form as a distinct species, pointing 

 out the following characters: The costulation is noticeably 

 coarser and more spaced than in P. downesii, with more pro- 

 jecting swellings and nodes. The cuticle is also coarser, and
