Euphorbia cyathophora (Willd.).^° Sandy shores of Spirit Lake, 
etc.; p. 160. 
Panicum virgatum (Linn.). Abundant on all the high prairies, but 
nowhere so luxuriant as near the Upper Des Moines river and Spirit 
Lake; p. 163. 
Agrostis cryptandra (Torr.). Banks of Spirit Lake, Little Sioux 
river, etc.; p. 164. 
Several additional species, reported from ‘‘between the Mis- 
souri and Mississippi rivers” also probably came from Iowa, 
but the references are not definite and the species are not listed 
here. 
Another of the older Iowa plant catalogues was published by 
Dr. C. C. Parry in Owen’s Keport on the Geology of Wisconsin, 
Iowa and Minnesota, pp. 608-621. This catalogue specifically 
refers 205 species to Iowa, though probably many of the re- 
maining species were also collected in the state, as Dr. Parry’s 
home was in Davenport, Iowa. As the Owen report is quite 
accessible the species are not listed here. 
ANIMALS. 
Several groups of animals have been included in the reports 
of earlier explorations. The records of mollusks, insects, reptiles 
and birds are of especial interest, though mammals and fishes 
also received some notice. 
Mollusks. 
No reference to mollusks is made in the Lewis and Clark and 
Nicollet reports, nor in the narrative of the Long Expedition 
although Say, a student of mollusks, was a member of the party. 
However, Say reported a number of species from “Council 
Bluff” (in one case including Engineer Cantonment, also in Ne- 
braska) in the Journal of the Academy of Sciences of Phila- 
delphia in 1821,^^ and later in the American Conchology.^^ 
These references' were subsequently copied by Haldeman,^^ 
Amos Binney,^"^ W. G. Binney in his edition of Say,"® the 
Bibliography,^® and the Land, and Fresh- water Shells of North 
20NOW E. heterophylla.

visit being a part of Missouri Territory.
