468 G. STEWARDSON BRADY. 



Paradiaptomiis falcifer {Loven). PI. XXXV^ figs. 7-10. 



This interesting species originally described and figured by 

 Loven (loc. cit.) has been recently found by Dr. Warren, 

 who has kindly sent me specimens which were taken in a 

 " pond between Witzies Hoek and Harrisniith." Dr. Warren 

 describes the colouring of these specimens as being — " the 

 body milky white, the antennee deep purple, the furcae bright 

 red round the base and purple terminally, the setse purple." 

 I give drawings of some of the characteristic parts — in all 

 respects similar to those of Loven and to those of more recent 

 authors.

Genus Ceriodaphnia Dana. 



Ceriodaphnia natalis Brady. 



Ceriodaphnia natalis Brady, Annals of the Natal Mnseum, vol. i, 

 p. 180. Pi. XXXII, figs. 3-7, 1907.

Genus Leydigia Kurz. 

 Leydigia quadridentata sp. nov. PI. XXXVI, fig. 10. 



This species, of which three individuals only were found, 

 has little to distinguish it from other members of the genus 

 excepting the presence of four minute but very distinct teeth 

 on the posterior margin of the valves. The valves are faintly 

 striated, and the caudal lamina? have the spinous armature 

 which is characteristic of the genus. The length is 0'5 mm. 



Obtained near to Victoria Falls (E. Warren).
