;= P. bulimoides. I possess this shell from the Museum Godeffroy. It = a 

 small, dark P. bulimoides. In Europe the typical P. bulimoides is called P. canals, 

 the small dark variety P. Upolensis, the sinistral greenish-yellow variety P. con- 

 ica. These, however, are only varieties of one species, and are all embraced in 

 Dr. Gould's description of P. conica " interdum sinistrorsa flavida vel castanea." 

 Like P. repanda, they are found only on mountains. 



f P. vakia Brod., P. Z. S., p. 125, 1832. Huaheine, Garr. The following 

 synonyms of this species are enumerated in the order of seniority : P. mucida, 

 P. assimilis, P. strigata ; manuscript species, P. pulchra, P. Cookiana, P. perplexa, 

 P. Huaheinensis, P. bicolor, Garr. (non Pse.). 



P. Vanicorensis Quoy et Gaim (Helix), Voy. Astrolabe, ii. p. 115, pi. 9, f. 12 

 -17, 1830. The original description and figure of this shell agree with dextral 

 specimens of P. Otaheitana, without a denticle. In collections it is sometimes 

 represented by P. affinis, and in others by P. Otaheitana. Dr. Gould says, " It 

 only differs from P. Otaheitana in the lighter color of the animal." 



f P. variabilis Pse., A. J. O, ii. p. 203 ; id., p. 81, pi. 1, f. 13-15, 1866-67. 

 Raiatea, Garr. = P. Navigatoria. This shell is the true P. Navigatoria Pfr., 

 agreeing with Reeve's figure and description, as well as with the types of P. Navi- 

 gatoria in the British Museum. Dr. Pfeiffer says, " My Navigatoria in the 

 British Museum was by Cuming confounded with another shell." From a 

 number of specimens in the Pease collection, labelled " P. Navigatoria Pfr., from 

 the British Museum," I infer that P. protea is the shell alluded to by Pfeiffer. 

 The possession of these doubtless led Mr. Pease to redescribe this shell. 



f P. ventrosa Garr., Mss. in Litt. Raiatea, Garr. = P. Hebe var. 



f P. ventricosa Pse., Mss. Coll. Pse., Tahaa = P. faba var. (Anthony). 



j P. vexillum Pse., A. J. C, ii. p. 198 ; id., iii. p. 81, pi. 1, f. 8, 1866-67. 

 Moorea, Garr. Reeve figures this shell for P. lineata Lesson ; others confound 

 it with P. elongata Pse. It = P. stenostoma Pfr. See Pfeiffer's Novitates 

 Conchologicse. 



f P. vittata Pse., A. J. C, ii. p. 194, 1866. Raiatea, Garr. 



f P. Virginea Pse. Mss., Coll. Pse. Tahaa, Garr. 



f P. virgulata Pse., J. C, 3d series, x. p. 401, 1870. Raratonga, Garr. 



f P. zebrina Gould, Proc. Bost. Soc. Nat. Hist., vii. p. 196, 1842. Tutuila, 

 Gould, Upolu, Garr., Belcher Island, Coll. Taylor = P. actor. Dr. Gould's type 

 of this shell is preserved in the collection of the New York State Museum of Nat- 

 ural History and also in the Smithsonian collection. The figures of this shell in 

 " Expeditionary Mollusks " are dissimilar ; figure SO is probably an error ; figure 

 81, containing the animal, is the true P. zebrina.
