ENTOMOSTRACA OF MINNESOTA. 303 
The palp of the mandible is stout, the terminal joint of the same is 
short. The blade of the female mandible is stouter than that of the 
male. 
The first maxilla bears a large leaf-like branchial appendage. 
The second maxilla of the female has the usual generic form, the 
palp being two-jointed and bearing at its tip three short sete. In the 
male the palp of the second maxilla is peculiarly modified and the 
palp of one side is larger than the palp of the other. 
The first foot is of the usual type. 
The second foot, as is always the case in this genus, bears at its tip 
two long and one short sete. 
The post-abdomen of the female is quite stout and bears at its tip 
two strong claws. This appendage is strongly curved. One claw is 
only about two-thirds as long as the other. 
The post-abdomen of the male is straighter than that of the female, 
but its borders are more irregular. The terminal claws are slender 
and of about the same size. 
The verticillate sac of the male bears seven whorls of chitinous 
spines. 
Habitat: Fayette county, Georgia. These specimens were found 
in the weedy shallows of a large millpond near Fayetteville, June 
21, 1894.

PLATE LXXI, FieGs. 35-40. 
1894.—Candona delawarensis C. H. Turner (215), pp. 21-22; Pl. VIII, Figs. 35-40. 
Length 0.95 mm. Height 0.54 mm. Width 0.43 mm. 
The color of this form is greenish yellow variegated with blotches 
of brown. 
Viewed from the side (Fig. 39) the shell of the female is sub-reni- 
form, the greatest height being about two-thirds the length of the 
animal from the cephalic extremity of the shell. The cephalic, dorsal 
and caudal margins are convex. The ventral margin is undulating, 
‘concave in the middle. 
Viewed from above (Fig. 37) the shell is an elongate ellipse with its 
greatest width in the middle. The extremities are pointed. The 
hinge-line is sinuous. Near the cephalic extremity there is a very 
pronounced sinuosity. 
Viewed from below (Fig. 38) the general outline is the same as when 
viewed from above. The contact line is more sinuous than the hinge- 
line. 
Viewed from the end the shell is elliptical. It is widest in the 
middle and the extremities are rounded.
