and its variety persulcata, Nevill, P. virgatus, Smith (fig. 49), P. 

 zonatua, A. Ad. (fig. 53), P. longispira, Smith (fig. 55), P. strigatus, 

 Hanley (fig. 59), and P. Hermannsem, Duuker (fig. 54.)

 shortly pilose epidermis, upon which the darker bands of the shell 



are somewhat elevated. 



Polynesia. 



P. striatula, Phil. (fig. 56), P. restitus, Dkr., P. plumbeus, Pease 

 P. pediGulus, Krauss, P. Bronni, Dunker are synonyms. 



This catalogue of synonyms may appear to some to be a ruthless 

 slaughter of species. I can only say that the admirable collection 

 before me fully justifies me. 

 P. PUNCTOSTRIATUS, E. A. Smith. PI. 53, figs. 60, 61. 



Whorls convex, with very minute punctured spiral striae, pale 

 fulvous, ornamented with spiral rows of small square chestnut 

 spots ; margin of outer lip spotted. Length, 6*5 mill. 



Hob. unknown. 

 P. TENUIS, E. A. Smith. PL 53, fig. 5*. 



Thin, elongated, polished, semipellucid, white, with a few distant, 

 spiral, red lines, lightly spirally grooved, body whorl strongly 

 grooved and ventricose below ; outer lip thin. Length, 5'5 mill. 



Hob unknown.

 sometimes with a darker peripheral band, smooth, with several en- 

 graved lines near the base, aperture }ellowish white.

Easter Island, Australia, Nicobar Is. 



First described by Lamarck under the name of P. Brasiliensis, 

 a misnomer. Other synonyms are P. pigra, Forbes, Bucc. Iceviga- 

 tum, Wood, P. fulvu, A. Ad. I think that P. Nicobar icus, Zelebor 

 (fig. 29), will prove to be at most a slight variety.
