shells, nor any of the varieties of varia" hence the name 

 simplaria should not be applied to them. Specimens of 

 various color-patterns are figured, pi. 23, figs. 9, 10. 



The form called P. glutinosa Pfr. is straw colored or pale 

 fulvous, the lip white with a purplish-brown border. It was 

 originally described as from the Solomon Islands. Fig. 11 

 is a copy of the original figure. A specimen received from 

 Cuming is drawn in fig. 15. "P. perplexa Pse. MS." of H. 

 H. Smith is the same. 



P. mucida Pfr. was based on the uniform chestnut colored 

 form of varia. A figure of the type specimen in the British 

 Museum is given, pi. 41, fig. 13.

The shell is openly perforate, rather thin, ovate-pyramidal, 

 moderately glossy ; under a lens it is seen to be marked with 

 fine growth-lines and close, waved, distinctly engraved spiral 

 lines. Whorls 5, very slightly convex, the last generally 

 angular at the periphery, in front of the aperture. The aper- 

 ture is ovate, slightly oblique ; outer lip well expanded, thin- 

 edged, strengthened with 'a narrow callous rim within, gradu-

 Parietal film transparent, toothless.

Length 23, diam. 13 to 15 mm. 



The typical color (pi. 22, figs. 1, 2) is uniform rose, in- 

 cluding the interior and lip ; but in many examples the em- 

 bryonic whorls are paler or yellowish with a pink sutural line. 



Huaheine : ' ' The headquarters of this beautiful and well- 

 known arboreal species is in a large forest at the head of 

 Hawai bay on the west side of Huaheine. From this region, 

 where they are very numerous, they have spread over many 

 parts of the island. They differ but little in .shape in the 

 different localities, except in Faahiti on the north coast, where 

 they (the P. cognata Pease) are smaller, less angulated on 

 the last whorl, and in the total absence of the uniform dark 

 purple-brown and rose-colored varieties which are so com-
