 1870. Rissoa polychroma de Folin, Fonds de la Mer, vol. 1, pp. 133-134, 

 pi. 20, fig. 5. 



Shell small, ovate, varying in color from violaceous through red- 

 dish, brownish, to horn white, ornamented with indistinct color 

 bands, which at times are almost lost in the ground color. Nepionic 

 whorls two, decidedly depressed, marked by pits which are arranged 

 in axial and spiral series. Postnuclear turns three, inflated, marked 

 by oblique lines of growth and fine spiral striations. Suture simple. 

 Periphery obscurely angulated. Base short, inflated, well rounded. 

 Aperture subcircular; outer lip thin; inner lip separated from the 

 body whorl. 



The type has five whorls and measures— altitude, 1.7 mm. ; diame- 

 ter, 1.1 mm. De Folin states tliat he had 20 specimens from the Bay 

 of Panama. We have not seen this species. 



BARLEEIA CALIFORNICA, new species. 



Plate 13, fig. 7. 

 Shell very small, broadly conic, pale brown, sometimes with a 

 lighter zone at the periphery and a darker band on the middle of the 

 base. Nuclear whorls one and three-fourths, well rounded, marked 

 by numerous, rather large, rounded pits, which are arranged in re- 

 tractively slanting axial as well as a spiral series, the spaces between 

 the pits being about equal to the diameter of the pits. Postnuclear 

 whorls moderately well rounded, almost appressed at the summit, 

 marked by somewhat retractively slanting incremental lines, and 

 very fine incised spiral striations. Suture moderately impressed. 

 Periphery of the last whorl obsoletely angulated. Base very short, 

 well rounded. Aperture very large, oval; outer lip rather effused at
