 Agrees excellently with original figure, &c.

2 Paumotu ; ex Mus. GodefEroy. 



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

 is, however, quite different. It is like a dwarf PL ahhreviatus.'\ 

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

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



15. Plauaxis acutus. 



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

 lin. ; var. = PI. simih's. Smith, Ann. Mag. XII, 1872, Sandwich Islands, 

 long. 11^, diam. 5| mil. 



The figm^es 11 and 12 of the Con. Iconiea. " P/. slmillsand PL 

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

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

 PL sim'dis 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.
