PLANAXID^J. 



12. Planaxis ater. 



Planaxis ater, Pease, Amer. Journ. Conch. F, 1868, Marquesas long. 8, 

 diam. 4 mil. [not PL ater of the Con. lcon.~] ; = PI. hanleyi, Smith, Ann. 

 Mag. XII, 1872, Sandwich Islands, long. 12, diam. 5% mil. 



1 Viti ; ex Mus. Godeffroy. 

 Agrees excellently with original figure, &c. 



13. Planaxis atropurpureus. 



Planaxis atropurpureus, Recluz, Rev. Zool. Cuv. 1843, p. 261, South Seas 

 anfr. 5 to 6 long. 7, diam. 4 mil. ; ? = PI. albersi, Dkr., Nov. Conch. 

 Sup. II, pi. II, Jig, 3537, W. Africa. 



2 Paumotu ; ex Mus. Godeffroy. 



Sent as " PL brevis, Quoy" [Guam and N. Guinea], which 

 is, however, quite different. It is like a dwarf PL abbreviatus.] 

 Long. 5, diam. 3 mil. ; anfr. 3. 



14. Planaxis semisuloatus. 



Planaxis semisulcatus, Sowerly, Genera Shells, I, 1824, Hab. ? ; = Purpura 

 nucleus, Lam. VII, 1822, {not Buc. nucleus, Brug. 1789, from Mada- 

 gascar]. 



12 W. Indies, exc. Prof W. Newcomb. 



1 St. Thomas; ex c. Colonel Godwin-Austen. 



15. Planaxis acutus. 



Planaxis acutus, Krauss, Siid Afrik. Moll. 1848, Natal, long. 6, diam. 3% 

 lin. ; var. =Pl. similis, Smith, Ann. Mag. XII, 1872, Sandwich Islands, 

 long. 11\, diam. 5% mil. 



The figures 11 and 12 of the Con. Iconica, " PI. similis and PL 

 hanleyi, Smith," both resemble more closely the original figure 

 of Krauss than does fig. 9, *' PL acutus ". I consider Smith's 

 PL similis doubtfully separable even as a variety. The species 

 varies much in size, and tendency to subangulation at the peri- 

 phery. PL ater, Pease, is scarcely more than a geographical race 

 or variety.
