ENTOMOSTRACA OF MINNESOTA. 301 



The mandibular palp (Fig. 31) is five-jomted. 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 maxillae 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 i)ortion 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 Eiver. 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 

 0.3L 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.
