ENTOMOSTRACA OF MINNESOTA. 301 
The mandibular palp (Fig. 31) is five-jointed. The first joint is 
large and bears at the distal angle of its inner margin a short dagger- 
like seta (Fig. 31). The distal half of this seta is pectinate. The 
mandibular blade is stout. 
The spines of the first mandibular process of the first maxille are 
non-pectinated. 
The first foot (Fig. 29) is long and slender and is composed of five 
joints. The second joint is about as long as the next two joints. The 
third and fourth joints are of about the same length. The fifth joint 
is the smallest of all. It is conical and from its distally directed apex 
arises the terminal claw. The terminal claw is slender and long. It 
is longer than the combined lengths of the last three joints and the 
distal portion is flexuose, 
The fourth joint of the second foot (Fig. 30) is somewhat obscurely 
divided into two joints, so that the second foot appears, under a high 
power, to be composed of six joints. The foot terminates in two long 
flexuose filaments and one shorter filament. 
The post-abdomen (Fig. 28) is of medium size. The terminal claws 
are slender, pectinated and curved. The terminal claw is about half 
as long as the abdominal ramus. The adjacent claw is a little shorter 
than the terminal claw. The filament in the caudal margin is about 
one-third the length of the ramus from the distal extremity of the 
post-abdomen. 
Habitat: Atlanta, Georgia, December, 1893. Abundant in the 
shallow ponds near South River. The ponds in which these speci- 
mens were found dry up in warm weather. 
Candona Peircei sp. n. 
PLATE LXXX. 
Length 0.70 to 0.79 mm. Height 0.33 to 0.37 mm. Width 0.22 to 
0.31 mm. 
The color of the shell is white tinged with yellow. The surface 
is highly polished and bears a few scattered hairs. The muscle 
impressions are sub central and the eye is not visible through the 
shell. The animal is about half as high as long, but is not quite so 
wide as high. 
Viewed from the side the shell is sub-reniform, the greatest 
width being a little caudad of the middle. The two extremities are 
rounded and are of about the same width. The dorsal margin is feebly 
convex, in some specimens it is nearly flat. The ventral margin is 
somewhat sinuous, the middle being slightly concave. In some speci- 
mens this margin is almost straight.
