other with the body ashen white, shading off darker on the varices, and 
another one of the typical coloring. 
Recently I have seen in the very fine collection of Dr. R. H. 
Tremper of Ontario, Cal., a magnificent series of this and other deep 
water shells, from the Santa Barbara channel, and perhaps the best 
collection of these shells extant, in good condition and artistically 
arranged to please the eye. Among the lot there is a series of Murex 
carpenteri, about typical in form and coloring, with the addition of 
three white revolving bands, that expand in width as they pass toward 
the outer edge of the foliated varices, and show on three of the spire 
whorls. There are three broad, thin varices on the specimen before 
me, the edge of the last broken by five rather broad, circular indenta-

tions, separated by four broad, rather short, chisel-shaped digitations, 
curved upward at the ends. The somewhat large basal indentation 
forms about two-thirds of a regular circle, is one-fourth of an ineh 
across, its edge thickened and regularly reflexed, except next to the 
lone, curved and well-covered canal. The body and varices are quite 
smooth, except the last varix, which is roughened on the lower side 
by wavy, file-like striae. 
These beautiful shells were dredged in the Santa Barbara channel, 
off Newport, by Dr. R. H. Tremper, who kindly gave me a specimen 
and to whom I dedicate this beautiful variety. 
OCINEBRA STEARNSI, HEMPH. 
The general outline of this small shell is diamond shape, with the 
side points rounded off. It is composed of six turns or whorls.
