Cyclops distinctus Lilljeborg, Synopsis specierum hue usque in 

 Suecia observatarum generis Cyclopis (1901). 



This species was found in most of the nettings. It is closely 

 allied to C. albidus Jurine. So far as appears from Mr. Lucas's 

 collections, it seems to be the prevailing form of Cyclops in the 

 New Zealand Lakes. 



Cyclops serrulatus Fischer. 



This common Northern species occurred, though only sparingly, 

 in several of the nettings ; but the serrulation of the caudal stylets 

 is seldom so distinctly marked as in European specimens. 



OSTRACODA, 



Genus Newnhamia King. 



Like N^otodromas, except that the mandibular palp bears a 

 small rudimentary branchial appendage the filaments of which 

 are directed upwards, and that the posterior maxillae have two 

 branchial filaments attached directly to the limb and not arising 

 from a distinct plate : the shell profusely tuberculated over the 

 whole surface. (Mr. King's description of the genus is : " eyes 

 two, distinct, pedunculated, with a corresponding tubercle on each 

 valve : a boat-shaped plate on ventral margin.")

Female. Shell seen laterally broadly elliptical ; height equal to 

 three-fourths of the length ; extremities rounded, subtruncate, 

 the anterior rather the narrower of the two ; dorsal margin 

 feebly arcuate, ventral rectilinear in the middle, rounded off 

 toward each extremity : seen from above (PI. L. fig. 2) the 

 outline is ovate, broadly rounded behind, tapering evenly from the 

 middle to the acuminate anterior extremity ; greatest width equal 

 to more than two-thirds of the length and situated behind the 

 middle ; the greater part of the ventral surface occupied by two 

 broad, sinuous flanges on the contact mai'gins of the two valves, 

 and by broad crescentic flattened plates stretching from these 

 flanges nearly as far as the lateral margins of the shell ; the 

 flanges are smooth and longitudinally sulcate, but each lateral 

 plate is beautifully ornamented with four roAvs of concentric 

 parallel rows of rounded tubercles (fig. 3) ; the general surface
