ACADEMY OF SCIENCES,

Recutar Murine, Jury 17, 1876.
Vice-President Edwards in the Chair.
Twenty-five members present.

Donations to the Museum: From M.D. Hyde, vial of mud
from soundings made from the ‘ Tuscarora.” From Henry
Bdwards, //yla, sp., Eutania sirtalis, Allorchestes plumulosus.

In the donations to the library was a volume of the ‘‘ Botany
of California,” to which the Vice-President called particular
attention. It is now published through the munificence of
certain of our citizens, the State Geological Survey having been
discontinued, and no money having been appropriated to publish
this work. As Judge S.C. Hastings had been mainly instru-
mental in obtaining the money by means of which the publication
of the work was insured, a vote of thanks to that gentleman
was passed by the Academy.

W. ON. Lockington submitted the following:

Check List of the Decapod and Tetradecapod Crustacea
of the West Coast of North America.

BY W. MN. LOCKINGTON.

The appended list contains 231 species, collected from the writings of Dana,
Stimpson, $. 7. Smith and Hale Streets, with the addition of above forty
recently described by Mr. W. G. W. Harford and myself.

Tt is not unlikely that other Panaman and Arctic forms may have been
described by American aad European naturalists, whose works are not acces-
sible to me; but I have worked in the belief that a check list was wanted, and
that the only way to have one was to avail myself of the materials at hand—
in the hope that those who have beticr materials, or more of them, will either
be so good as to send me their additions or corrections, or will publish a
fuller and better list.

Kiven if this list should prove complete, or nearly so, as regards species
hitherto described, it probably docs not contain the half of those actually
the long line of coast stretching from Panama to the Aretic Ocean.
more conspicuous species from the coast north of Monterey have

Panama, lies a va
searched at all for Crustacea, though ite birds, reptiles, fishes and mollusks
have been preity thoronghly studied.

64 PROCEEDINGS OF THE CALIFORNIA

Numerous Decapoda from Panama and Nicaragua have recently been
described by S. I. Smith, and others by Hale Streets, yet the series of new
forms given by them must be considered only as a sample of the riches of
that region.

Even in and around San Francisco Bay we have found several new species
of Tetradecapoda, and probably a systematic dredging would bring to light
many more.

Very little dredging has been done along the coast, and that little has been
confined te comparatively shallow depths.

The fresh-water streams and lakes of California, as well as those of Mexico,
have yet to yield their quota of species for some future check list.

‘The Entomostraca and Cirripedia as yet describe! are very few, and these
departments offer a large and inviting field to the naturalist.

It is my intention, from time time, to furnish the Academy with additional
notes of the species already known, as well as descriptions of such new
species as may be sent to us.

Some few of the new species included in this list may, without doubt, prove
to have been already described, but I feel assured that this will only be the
case with Alaska forms, some of which may probably range throughout the
Arctic Seas, inhabiting both North Pacific and North Atlantic.

The names of the naturalists who have described species are given in full
throughout this list, with the exception of Stimpson, which is abbreviated
to St.

The species at present in the collection of the Academy are denoted thus *
