capture of part of the Mississippi drainage, owing to changes of level,

This singular shell hardly more than crosses the boundary, so far as
reported. According to Stearns and Hemphill this species buries itself
obliquely in the rather hard bed of rapid streams, so that the flattened
posterior portion lies horizontally even with the bottom, and offers no
resistance to the current. Whether the flattening and consequent angu-
lation of the valves is a modification due to the burrowing habit and
the influence of its environment, or not, cannot yet be positively stated.

Range of the type. The whole of northern Europe and western
Siberia. In northeastern Asia from the Upper Amur basin and south-
ern Mongolia, Kamchatka, and Sakhalin Island. In America on Anti-
costi Island ; Quebec Province, eastern Canada ; New England and
New York. Also, isolated from the eastern area by a wide gap, in
the Lower Saskatchewan near Lake Winnipeg.

Range of the "variety. California, in the Sierra, Plumas Co., at
7,400 feet above the sea ! Sacramento River ; Yuba River ; Oregon ;
Washington at Wallawalla ; northwestern Montana in the headwaters
of the Missouri ! (only) above Fort Benton, but not reported lower

Kakwous Lake (4,000 feet elevation) and streams in Lat. 50, Brit-
ish Columbia ; Naha Bay, Alaska, abundant near sea level in small

The most obvious distinction between the typical form and variety
falcata lies in the purple nacre of the latter, which is often extremely
rich and beautiful, though in old cabinet specimens usually much
faded. The specimens above the falls in the headwaters of the Mis-
souri may have been captured with streams by orographic changes,
or transported in the glochidium stage attached to fishes ; at any rate

they are of the Pacific type, and are not found below the site of Fort
Benton, so far as yet reported. It is quite evident that much scientific
interest attaches to a thorough knowledge of the distribution of this
species, with its possible relation to geologic changes and the results of
glaciation. It is to be hoped that any data bearing on this matter will
be carefully preserved and put on record by travelers and others in
these regions.

Family SPRERIIDJB.

This family is reviewed in Trans. Wagner Institute, vol. in, part
vi, pp. 1439-60, and a summary of the arrangement adopted is also
given in Proceedings Biological Society of Washington, xvi, pp. 5-8,
1903. This arrangement in effect is that which is adopted on the
present occasion. The specific synonymy is mainly due to the late
Temple Prime, who kindly named the Alaskan specimens collected
previous to his death. Some later arrivals have been examined by Dr.
Sterki. I have seen no specimens or figures of the species from Port
Clarence named by Westerlund, and they are introduced on his author-
ity. It is probable that a considerable reduction will eventually be had
in the number of nominal species, especially of Corneocyclas.

This attractive species is apparently sporadic or local in its habitats,
but if intelligently sought for would probably be found more often.
It is not yet positively known from British Columbia, but there is little
reason to doubt it will be found there when the fauna is better known.
So far it seems to be rather rare everywhere.
