Article V. — List of the Described Species of Fresh Wafer
Crustacea from America, North of Mexico. By Lucien
M. Underwood, Ph.D.

INTRODUCTOEY.

The economic relations of the fresh water Crustacea are
rapidly calling them into general notice, since their importance
as the natural food supply of many of our most valuable fishes
is established beyond question. It has seemed desirable that
our scattered literature on this subject should be indexed and
made available to students. The following preliminary list is
not intended as a complete arrangement of genera and species.
A thorough revision of many of these groups must precede any
permanent arrangement, and this is not possible at present.
It is, therefore, merely an index to the described species, with
such references to American and foreign literature as will
place the student in a position to make use at once of all that
pertains to each species. In case a full synonymy is given in
standard works, like those of Leydig, Glaus, P. E. Miiller,
Brady, etc., it has not been thought desirable to repeat this
synonymy, but merely to refer to the author giving it in full.
For this reason all the European papers are not repeated for
all the species they describe. In the American literature, how-
ever, it has seemed desirable to give every reference to each
species, even at the risk of too great repetition.

The study of our fresh water Crustacea, with that of their
marine congeners, commenced with Thomas Say, and has since
attracted the attention of over thirty different writers, nearly
all of whom have added one or more new species to our lists.
Certain groups, like the PlrtjUopoda and Astacida\ have been
carefully monographed, and furnish a literature of great value;
in others sufficient work has been accomplished to furnish a
broad, if not a substantial, basis for further study; while in

824 Illinois State Lahoi-atorij of Naturdl History.

several others the ground has scarcely been broken, save by
the brief and miscellaneous descriptions of new species. As
in all such miscellaneous work there has been much looseness
of definition and probably partial or complete re-description,
many of the species as given in the following list will ulti-
mately be reduced to synonyms or otherwise disappear from
sight. While we deplore this looseness we cannot wholly
ignore work because it has been poorly performed, as some of
our recent carcinologists have been prone to do.

The species of fresh water Crustacea, as given herein, com-
prise 313 names, distributed in 88 genera and 29 families, as
follows :

COPEPODA ....
OSTRACODA ...

Cladocera ...
Phyllopoda.
Amphipoda..

As to the relative abundance in the different sections of
the country, too little is now known of the range of individual
species to form any satisfactory conclusions. The following
geographic table will, therefore, show the comparative amount
of attention each group has received in different sections
rather than an exact representation of geographic distribution :

326 [llino'is State Lahomtory of Natural Historij.

In the above numbers Minnesota takes the lead with 82
species, owing to the extended study of the microscopic forms
by Prof. C. L. Herrick. Massachusetts with 48 and Wisconsin
with 34 owe much to the study of the Cladocera by Prof. E. A.
Birge. Illinois with 30, to which might properly be added
most of the 15 of Lake Michigan, shows the careful research
of Prof. S, A. Forbes. Other states owe their relatively high
rank to the elaborate monograph of the Astacidaj, by Dr.
Faxon, that has recently appeared. The contrast between the
States above mentioned and others shows the nature of the
work for future investigators. When we consider that twentij-
seven of the above States and territories do not exceed ten
species (seventeen not exceeding five), and add Delaware,
Nevada, Arizona, and Indian Territory, from which no species
have been reported, we can begin to realize how meagrely the
group has been studied. There ought to be a response by some
one, or by many, from all these neglected regions.

Of the seven orders the Copepoda* Ostracoda and Clado-
cera, including all the microscopic forms, have been studied
only in the eastern half of the United States, if Ave except six
species reported from Colorado by Chambers. In sharp con-
trast with this, 20 of the 34 PhyUopoda are known only west
of the Mississippi River. Of the 17 Amphipoda four extend to
Colorado, five to the Southern States, while the remainder seem
confined to northern waters. The Isopoda and Decapoda are
more uniformly distributed, and with the PhyUopoda extend
to the Pacific coast.

The largest genera are Cambariis, with 50 species, Cyclops
with 21 species, Daphnia with 15 species, PorcelUo with 15
species, Cypris with 11 species, all the rest falling below 10.
Forty-one of the 88 genera are represented by a single species.

In the preparation of this list the compiler has been
greatly aided by kind-hearted zoologists who have furnished
copies of their papers, cited references, corrected synomymies,
and otherwise contributed to the completeness of the list.
Their generosity entitles them to public thanks by the compiler
and by all who may use this list when published. Their names

*This remark does not properly apply to the parasitic forms, as
some species have been reported from the Pacific coast.
