A LIST OF THE ENTOMOSTRACA OF COLORADO 249 
Erpetocypris olivacea Norman and Brady. 
Greeley. 
Ilyocypris bradyi Sars. 
Greeley. 
In the above list, one species, Daphnia brevicauda, must be thrown 
out. In two cases two varieties of the same species are listed separately 
This makes the total list as follows: Phyllopoda 8 species; Cladocera 
26 species; Copepoda 18 species; Ostracoda ro species. This makes 
a total of 62 species.
