8 BULLETIN OF THE LABORATORIES 



joint arises a long claw ; this claw is much longer than the joint and 

 appears to be composed of two portions ; a short proximal and a long 

 distal portion. From the cephalic margin of the proximal portion 

 arises a short seta. 



Second foot of female [fig. 6] composed of four jomts, the joints 

 diminishing in size from the most proximal to the most distal joint. 

 The most proximal joint bears at about its proximo-caudal angle a 

 long plumose seta which is as long as the joint; and from the distal 

 third of its cephalad margin arises a somewhat shorter seta. From 

 the distal fourth of the cephalic margin of the antipenultimate joint 

 arises a seta. From a corresponding point on the penultimate joint 

 there also arises a seta. From the extremity of the terminal joint 

 arises two long and two short setae. The two long setae are about as 

 long as the combined lengths of both the ultimate and the penultimate 

 joints. The two shorter setae are but little longer than the terminal 

 joint. 



Post abdomen [fig. 7] is curved, bearing one terminal claw and 

 at its base a short terminal spine. On the convex surface there is a 

 sub-terminal claw. 



Verticillate sac [fig. 8] of male as usual in this genus. It seems 

 to be enclosed by a transparent capsule. 



Length of female, 0.52 mm. Height, 0.36 mm. Breadth, 

 0.26 mm. 



Habitat: This little species is very abundant here. The major- 

 ity of the ponds that contain either grass, water plants or hydrodic- 

 tyon, contain it. Found at Tusculum, Clifton, Mill Creek bottoms. 



Genus Cypris, Miiller. 



Cypris inco7tgrne7is, . . Ramdohr [PI. I; fig. 9, 16; pi. II, fig. 17, 21.] 



Cypris incongruens, . . . G. S. Brady. Recent British Ostracoda, 



pp, 362, 363; pi. XXIII, figs. 16, 22. 

 Cypris incongruens, . . . G. S. Brady and Alfred M. X'orman. 



Mon. of Marine and Fresh Water Ost. of N. At. and N. W. Europe; Part 



I, PP- 73^ 74; ph XII, figs. 8, 9. 



The American representative of this species is almost an exact 

 counterpart of the European species. A comparison of the figures 

 given here with those in the monographs referred to above, will show 

 how close is the resemblance. 



Length of female, 1.35 mm. Height, 0.75 mm. Habitat: Rare. 

 Found in stagnant water.
