Shell elongate conic, pale chestnut brown. Nuclear whorls almost 

 two, well rounded, marked by curved, axial rows of pits which are 

 also arranged in spiral series. Postnuclear whorls moderately well 

 rounded, almost flat at the summit, marked by fine incremental lines 

 and exceedingly fine closely spaced spiral striations. Suture moder- 

 ately constricted. Periphery of the last whorl obscurely angulated. 

 Base moderately long and moderately rounded, marked like the spire. 

 Aperture rather small, oval; posterior angle obtuse; outer lip thin; 

 the basal and inner lip meet in a well-rounded curve ; inner lip ap- 

 pressed to the base, except at the anterior third, which is free; parie- 

 tal wall covered by a thick callus which renders the peritremo com- 

 plete; operculum typical. 



The tyjDe, Cat. No. 15558, U.S.N.M., was collected on the back of a 

 Haliotis by Rowell in Lower California. It has almost six whorls 

 and measures: altitude, 2.5 mm.; diameter, 1.3 mm. This species 

 closely resembles Barleeia oldroydi. It is, however, uniformly 

 smaller, with a decidedly smaller aperture.
