Shell dextral, imperforate, solid, pyramidally conical, apex 

 obtuse ; surface shining, covered with very delicate incremental 

 lines ; the nuclear whorls smooth. Color light gray, shading into 

 light chestnut on the apical whorls, the gray more intense under 

 the cuticle ; with two black lines, one below and one at the 

 periphery, the latter faint and continued on the spire ; between the 

 lines a white band which revolves on the suture to the very tip of 

 the apex. Whorls 6, margined above, slightly convex; suture 

 lightly impressed. Aperture oblique, oval, white, the light gray 

 of the exterior surface exhibiting a darker shade within ; peris- 

 tome acute, slightly thickened within, a little expanded, columellar 

 margin very slightly reflecled, white, the coloring of the exterior 

 dark lines reappearing rather more intense on the inner edge ; col- 

 umella white, terminating in a moderately developed flexuous fold. 

 Length 15, diam. 9 1-2 mm. 



No opportunity for an examination of the animal has yet oc- 

 curred. The shell is typically very distinct from an}' other known 

 species. The light chestnut band on the apical whorls is a char- 

 acteristic and invariable feature. The basal portion of the shell 

 sometimes has a j-ellowish hue. In immature shells the colors are 

 more intense. 



Named in honor of Hon. A. F. Judd, Chief Justice of the 

 Repu])lic of Hawaii, by whose son the shell was discovered. — Bald.
