This southern species has heretofore been found only at its type 
locality within the Santa Barbara channel. It is represented in the 
Survey collections mainly from the stations outside the Golden Gate. 
Living specimens were dredged from a bottom of dark greenish sand 
at depths ranging from 39 to 46 fathoms. 
Range.—San Francisco to Coronado Islands, California.

Description.—This species was described by Tryon (1887) as follows: 
“«Whorls convex, rapidly increasing, smooth or very minutely spirally striate, 
light chocolate color, shining, under a thin olivaceous epidermis, speckled and 
spotted irregularly with white, interior chocolate color, with a white band near 
the base; columella broadly excavated, yellowish brown.’’ 
Height, 3 to 14 mm. 
Occurrence—At Bonita Point (13, 2), and questionably at D 5742. 
This littoral species was reported by Carpenter (1863) from the 
Farallon Islands and from San Francisco where it has been found by 
subsequent writers. It is a common form upon the rocks or piles at 
or above high-tide level. It is represented in the Survey collections 
by specimens from the beach at Bonita Point and questionably at one 
dredging station within the middle division of the bay. 
Range—Sitka, Alaska (Cooper) ; Lower California (Orcutt).

Height, 2 to 9 mm. 
Occurrence—At stations D 5739 (1), Key Route Pier, Oakland 
(63), Standard Oil Pier, Richmond (29), Red Rock (11), Presidio 
(60), Sausalito (2), Bonita Point* (162, 3).
