BARLEEIA CORONADOENSIS, new species. 



Plate 13, flg. 5. 



Shell ovate, white. Nuclear whorls two and a fifth, well rounded, 

 marked by numerous pits, which are arranged in curved axial lines 

 as well as in spiral series. Postnuclear whorls strongly rounded, ap- 

 pressed at the summit, marked by feeble incremental lines and ex- 

 ceedingly fuie spiral striations. Suture rather constricted. Periphery 

 of the last whorl strongly rounded. Base moderately long and Avell 

 rounded. Aperture large, broadly ovate, rather effuse at the junc- 

 tion of the base and outer lip; posterior angle obtuse; junction of 

 the inner and basal lip well rounded; outer lip thin; inner lip well 

 rounded, reflected over and appressed to the base except at the ex- 

 treme anterior portion where it is free; parietal wall covered by a 

 thick callus, which renders the peritreme complete; operculum 

 typical. 



The type and six additional specimens. Cat. No. 226453, U.S.N.M., 

 were collected in 7-10 fathoms off Coronados Islands, northwest coast 

 of Lower California. The type has four and one-fifth whorls and 

 measures — altitude, 1.3 mm. ; diameter, 9 mm. 



BARLEEIA CARPENTERI, new species. 



Plate 13, fig. 4. 



Shell elongate ovate, white. Nuclear whorls two, well rounded, 

 marked by numerous pits, which are arranged in axial and spiral 

 series. Posterior whorls narrowly, tabulately shouldered at the sum- 

 mit, more so on the early whorls than on the last, well rounded, 

 marked by slender, curved incremental lines and fine spiral striations. 

 Suture well marked. Periphery of the last whorl strongly rounded. 

 Base moderately long, well rounded. Aperture ovate ; posterior angle 

 obtuse; outer lip thin at the edge; inner lip strongh- curved, ap- 

 pressed to the base, free only at the anterior fourth; parietal 

 wall covered by a thick callus, which renders the peritreme complete ; 

 the summit of the last whorl falls slightly below the periphery at 

 the aperture. 



The type. Cat. No. 16215, U.S.N.M., comes from St. Lucas, 

 Lower California. It has 4.8 whorls and measures — altitude, 1.6 mm. ; 

 diameter, 1.1 mm.
