SCAPHELLA STEARNSII Dall.

pi. I, fig. 1. 
Shumagin l.*ilands, Alaska, and westward to Captains Bay, Unalaska, 
in 40 to 100 fathoms. U.S.N.M., 91352. 
The original figure of this species is not ver}' accessible and was 
made from a rather imperfect specimen, hence I have figured a char- 
acteristic individual. 
This fine species is separated by several thousands of miles from its 
nearest congener, and is perfectly distinct from any other. The 
purplish inner layer covered by a porcellanous bluish-white outer 
stratum is not paralleled among the volutes. Yet with astonishing 
absurdity it has been united with Scaj?hella anciUa of the opposite end 
of the world b}" a conchologist of some note, who, it is charitable to 
suppose, has never seen a specimen. 
FUSUS ? (ROPERIA) ROPERI Dall. 
Plate XXXIV, fig. 3. 
Fufnis (Roperia) roperi Dall, Nautilus, XII, -May, 1898,- p. 4. 
San Pedro, California, in rather deep water, E. W. Roper. Also 
fossil in the Pleistocene of San Pedro, Arnold. U.S.N. M., 151735. 
This singular species is of a ferruginous brown, with the pillar and 
throat whitish, and with narrow brown spiral lines showing on the 
interior margin of the outer lip.

Dall, Rep. Int. Polar Exp. to Point Barrow, Alaska, 1885, p. 179, figs. 1-4. 
Buccinum stimpsoni Gould, Proc. Bost. Soc. Nat. Hist., VII, 1860, p. 325. 
Shores of the Polar Sea near Bering Strait, Beechey; Point Barrow 
and Cape Smythe, low water to 5 fathoms, Murdoch. U.S.N.M., 
10966, 40967, 122555. 
The Point Barrow report is not generally accessible, and, though it 
contains excellent figures of several of these arctic Buccinums, with 
magnified drawings of the minute sculpture of their surfaces, so 
important for identification, I have thought it desirable to refigure 
several of them here. Most of these arctic Buccinums have two forms 
apparentl}^ correlated with sex, the males being in several species far
