ORTMANN: THE CRAWFISHES OF THE STATE OF PENNSYLVANIA 405 
green and whitish. The relative amount of green and brown changes very consider- 
ably with different specimens, but in general we may say that green prevails in the 
young, and brown in older specimens. 
Color of newly laid eggs buff (V, 13); when more advanced prune-purple 
(VILL, 1), or indian-purple (VIII, 6) on one side, eream-color (V. 20), or dirty-white on 
the other. 
In the Carnegie Museum there are altogether three hundred and twenty-three 
specimens of this species, of which twenty are from eastern and two hundred and 
sixty-six from western Pennsylvania. Two specimens are from Maryland, five 
from West Virginia, twenty-four from Indiana and three from Iowa; while one speci- 
men is from each of the states of Delaware, Ohio, and Kansas.
