114 Excursion to A Iphington. Ivok'xxix. 



common forms of Cladocera were taken, including Bosmina and 

 Ceriodaphnia, but Daphnia carinata, usually so plentiful, was 

 conspicuous by its absence, not a single specimen being seen. 

 A search was made for a rare form of Cladocera, possessing an 

 arrow-shaped head, single specimens having been taken in these 

 ponds at wide intervals during thirty years' collecting ; but so 

 far our search has been unrewarded. Of the Phyllopoda, 

 Lepiduris viridis and Enlimnadia dahli were taken. Ostracoda 

 were numerous, but mostly small species, Cypridopsis minna 

 being the most common. Among the Rotifera large numbers 

 of a very large species of an Asplanchna (both male and female 

 forms) were taken, also three forms of Anursea, a few clusters 

 of Lacinularia, and the tube-builder, Melicerta. Volvox was 

 present in all the ponds. The commonest water plants were 

 Myriophyllum and an aquatic Ranunculus, the latter just 

 coming into flower, while from the swampy ground plants of 

 the Nardoo, Marsilea quadrifolia, were secured for home 

 cultivation. The varied tints of the young foliage of the gums 

 and acacias were greatly admired by the ladies of the jmrty, 

 while the melody of song from the throats of many beautiful 

 native birds, assisted by that great soloist the English Skylark, 

 was gratifying to all. Laden with material for home study, 

 the party returned homewards well pleased with their outing.
