specimens were taken in depths up to 13 fathoms and a single shell 
from 40 fathoms. It occurs on bottoms that are prevailingly sandy. 
Range.—Known only from San Francisco which is the type locality 
of the species. 
Turbonilla keepi Dall and Bartsch 
Plate 36, figures 12a and 12b 
Turbonilla keepi Dall and Bartsch (1909), p. 71, pl. 5, fig. 1. 
Description—This species was described by Dall and Bartsch (1909) as 
follows: 
““Shell elongate-conic, yellowish-white with a brown band about two-fifths 
the width of the space between the sutures, immediately below the summits, 
and one about one-third as wide, a little anterior to the middle of the remaining 
light area. Posterior half of base a little lighter brown than the bands between 
the sutures, grading into white on the anterior half. (Nuclear whorls decol- 
lated.) Postnuclear whorls slightly shouldered, flattened, somewhat contracted 
at the periphery, marked by strong, well rounded, almost vertical axial ribs, 
of which there are 22 upon the fourth to sixth, 24 upon the seventh to ninth, 
26 upon the tenth, and 30 upon the penultimate turn. Intercostal spaces a little 
narrower than the ribs, well impressed. Sutures strongly impressed, rendered 
sinuous by the strong terminations of the axial ribs at the summits of the 
whorls. Periphery of the last whorl well rounded. Base moderately long, well 
rounded. Entire surface of spire and base marked by numerous, very closely 
crowded, wavy, spiral striations. Aperture large; posterior angle acute; outer 
lip thin, showing the external sculpture and color bands within; columella 
very oblique, almost straight and slightly revolute.’’ 
Height, 6 to 11 mm. 
Occurrence.—At stations D 5785 (1), D 5786 (2), D 5826 A (64). 
This small univalve has not before been taken as far north as San 
Francisco. It is restricted in the Survey collections to the waters 
of the open ocean. Living specimens were dredged in 39 to 40 fathoms 
from a sandy bottom. 
Range.—San Francisco; Catalina Island to San Diego, California 
(Dall and Bartsch).

Odostomina (Evalea) franciscana Bartsch (1917), p. 665, pl. 45, fig. 7. 
Description—This species was recently described by Bartsch (1917) as 
follows: 
“*Shell thin, broadly elongate conic, yellowish white. Nuclear whorls small, 
deeply imbedded in the first of the succeeding turns, about which the tilted edge 
of the last volution only projects. Postnuclear whorls inflated, well rounded, 
feebly shouldered at the summit, marked by almost vertical, very feeble, incre- 
mental lines and exceedingly fine, closely spaced spiral striations. Suture
