15. Planaxis aeutus. 



Planaxis aeutus, Krauss, Sild — AfriTc. Moll. 1848, Natal, long. 6, diam. 5g 

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

 long. Hi, diam. 5k mil. 



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

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

 of Krauss than does fig. 9, •' PL aeutus ". 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.
