while the shrubs surrounding them are mostly low-growing and 

 spreading, showing the presence of high winds and snow in 

 winter. The yearly rainfall is probably over 60 inches, and for 

 several months the plateau is a snow-covered waste. ^lost of 

 the notable plants belong to the CompasitcT, Epacrid?e, or 

 Myrtaceae."

EXCURSION TO HEIDELBERG. 



About six members took part in the excursion to Heidelberg 

 on Saturday, the 28th Febniary, which was set down for pond- 

 life. The first pond visited — that by the roadside, near the 

 bridge over the Yarra — was found to be nearly dried up, as 

 was anticipated, after the long-continued spell of dry weather. 

 Those who essayed to reach what water remained were nearly 

 engulfed in slimy mud. Leaving this pool, we proceeded to 

 two others and obtained more satisfactory results, so that our 

 bottles were finally filled with fairly good material. Some of 

 the larger denizens of the ponds, such as the brown hydra, 

 the bug commonly known as the water-boatman, Notoneda 

 glmtca, sundry crustaceans, &c., were examined on the spot, 

 and appeared to interest the party considerably. On the 

 whole, we think a pleasant and profitable afternoon was spent. 

 A microscopic inspection of our material yielded the following 

 results : — Protozoa were found to be numerous. Of these 

 some amoeboid forms, the shell-forming rhizopod Arcella 

 vulgaris, and a few heliozoa represented the Sarcodina. The 

 Mastigophora, or flagellates, noted included Astasia tricophora, 

 Ehr., and Anthophysa vegetans, Miiller. The latter are very 

 minute protozoa which iorm clusters, the clusters being 

 attached to water-weeds by stalks of comparatively con- 

 siderable length. The Infusoria or ciliated division were more 

 numerous, and included the following : — Epistylis flavicans, 

 Ehr., E. plicatilis, Ehr., two or three species of Vorticelli, 

 Trachelocerca olor, MiilL, Coleps hirtus, Ehr., a hypotrichous 

 form, probably Euplotes harpa, Stein., and also a large group
