the same day, all with the aperture imperfect—no description 
of this part can be given. I only retained one specimen for my 
cabinet. Prof. Keep refers to a variety of moesta which he says 
““ig smooth, with fine color lines.’’ He gives San Pedro as the 
locality. I have no personal knowledge of other than the three 
I collected at the Point. It is not listed in his Check List. 
Leneth of shell 20 mm. For Drillia moesta consult Arnold’s 
Memoirs Cal. Acad. Sciences, Vol. III, page 209, Tryon’s Mem. 
Conch. Vol VI, page 183, plate 12, fig. 38: and Keep’s West 
"Amer. Shells, page 159. 
Drillia torosa var. aurantia Cpr. 
Monterey from Mrs. E. H. King. 
This differs only in color from typical torosa. Mon. Conch., 
by Tryon, Vol. VI, page 183. 
MITRIDA 
Genus Mitra Lamark 
Mitra fultoni E. A. Smith. 
This is considered by some West Coast conchologists a variety 
of M. maura Swaino. The latter name was changed in 1893. 
to M. ide by Prof. James Cosmo Melvill, M. A., F. L. S., and 
that name is now used by British conchologists, but not by 
conchologists in this country. Of M. fultoni Dr. Dall says he 
has seen none north of San Diego. M. fultoni and M. maura 
ean readily be separated by collectors. My specimen was eol- 
leeted by Mr. Henry Hemphill. 
NASSIDA 
Genus Nassa Lamark 
Nassa mendica var. elongata Stearns. 
Santa Catalina Island, Cal. 
As the name would indicate this variety is of unusual length, 
the type measuring 22 mm. Five apical whorls show the strong 
ribs of var. cooperi but in the remaining two whorls these ribs 
are obsolete, the surface being marked with fine lines, many 
are considerably granulose. This var. was originally listed from 
a MS. name in *‘ Annotated List of the Shells of San Pedro Bay 
and Vicinity,’’ (Proc. W.S. Nat. Mus. Vol. XV), page 213, and 
no deseription was given. 
COLUMBELLIDA: 
Genus Columbella Lamark 
Columbella (Astyris) carinata var. hindsii Rve. 
San Diego, Cal., and Wash. 
The value of the many variations of the forms carinata and 
guasapata is a debatable one but if some variations are admitted
