f P. clara Pse., P. Z. S., p. 671, 1864. Tahiti, Garr. In the Smithsonian 

 collection this species is regarded as = P. hyalina ; it is doubtless a good species. 

 Mr. Garrett informs me that it seems to be rapidly disappearing from the island 

 of Tahiti. 



f P. cognata Pse. Mss., Mus. Godeff. Cat., v. p. 92, 1874. Huaheine, Garr. = 

 P. rosea var. 



f P. compacta Pse., A. J. C., ii. p. 200 ; Id. iii. p. 81, pi. 1, f. 9, 1866-67- 

 Raiatea, Garr. This shell possesses the keyhole aperture of P. auriculata ; it is a 

 good species. 



f P. compeessa Pfr. Mss. (Bui.), Mus. Cuming, Conch. Icon. Mon. Part., spe- 

 cies 20, pi. 4, f. 20, 1850, Fiji Islands, coll. Taylor. This shell is very rare in 

 collections. 



f P. concinna Pse., A. J. C, vii. p. 196, 1872. Tanna, New Hebrides. Mr. 

 Pease remarks, " This shell is the type of P. repanda " ; it resembles it in con- 

 tour, but is less than half the size of P. repanda. 



f P. conica Gould, Proceedings Boston Soc. Nat. Hist., p. 196, 1848. Rarkaa 

 and Samoa Islands, Gould. Upolu, Garr. Tulare, Navigator's Islands, Cox = 

 P. bulimoides. 



P. Cookiana Mouss. Mss., p. 28, f. 28, 29. Raratonga (Garr. in litt.) = P. 

 assimlis ? 



f P. Coxi Angas, Cox, Cat. Land Shells of Solomon's Island, p. 46, 1868. 

 Ysabel and Solomon's Island, Dr. Cox. I have been unable to find any notice 

 of this shell except in the catalogue of Dr. Cox. Specimens labelled P. Coxi 

 from several correspondents = P. grisea ; those from Dr. Cox = P. micans. 



f P. crassilabris Pse., A. J. C, ii. p. 199 ; Id. iii. p. 81, pi. 1, f. 6, 1866, 

 1867. Raiatea, Garr. 



f P. crassa Pse. Mss., Mus. Godeff. Cat., v. p. 92, 1874 = a sinistral short 

 heavy specimen of P. Otaheitana. Tahiti. 



P. crassiuscula Garr. Mss. in litt. in Mus. Godeff. Pacific Isls., Garr. 



f P. decorticata Pse. Mss., Coll. Pse. Raiatea = P. dentifera denuded of epi- 

 dermis. 



f P. dectjssatula Pfr., P. Z. S., p. 131, 1850. Con. Icon. Mon. Part., 

 species 24, pi. 4, f. 23, 1849. Dominique, Marquesas, Garr. Samoa, Pse. 

 Navigator's Isls., Dr. Cox. 



f P. dentifera Pfr., P. Z. S., p. 85, 1852. Raiatea, Garr. Solomon's Island, 

 Dr. Cox. 



P. diminuta C. B. Adams, Ann. Lye. Nat. Hist., v. p. 81, 1850. Society Islands. 

 I. have been unable to identify this shell. It would seem that the typos in the 

 Adams collection are lost. From the description I am inclined to believe it a 

 variety of that protean species P. Otaheitana. 



f P. dubia Garr. Mss. in litt. Tahaa, Garr. = faba dentate var.* 



f P. elongata Pse., A. J. C, ii. p. 196; Id. iii. p. 81, pi. 1, f. 2, 1866-67. 

 Moorea, Garr. = P. spadicea var. 



* Andrew Garrett, of Huaheine, will describe the Mss. species of Mr. Tease and 

 himself which are marked as good species in this catalogue.
