Compare P. sennaariensis. A topotype from Preston is 

 drawn in pi. 17, fig. 4. It is a smaller, more delicate shell 

 than P. ccenopictus, with the narrower lip but slightly thick- 

 ened ; possibly not fully mature. Length 4.1, diam. 1.8 mm. ; 

 51/0 whorls (B. Walker coll., no. 41592).

 deeply impressed, umbilical area broadly depressed; labrum 

 with converging upper margin, white, rather broadly ex- 

 panded; aperture ovate. Alt. nearly 4.5, diam. maj. 2.25,
