of respiratory organs of a typical land form. Between the 
rocks further down were particularly noted the white armoured 
shell Thais, the blackerow, Nerita, and the common periwinkle, 
the showy Triton and many others. The rock-pools at a lower 
level yielded:—Galeolana, the gregarious annelid, which here 
“white-washes” the rocks. Portions of this were broken off, 
and the branchiae were examined. From the side of a rock- 
pool three very beautiful specimens of the tube-infesting poly- 
chaete, Spirographis australiensis, were examined. 
Sea-anemones, Paradis (sea-waratah) Oulactis (sea dahlia), 
and other species were seen, and a specimen of the ascidian 
(Boltenia australis) was found. Other specimens included the 
eight-rayed starfish, Astenna calear, the five-rayed form, A. 
exigua, the sprawling starfish, Coscinasterina sp., the dark-sea 
urchin with thick spine, oxocidaris sp. and the common sessile 
barnacles, Tetrachta and Chthamalus, and several species of 
erabs. 
The tide was unfavourable for the collection of seaweeds, 
but the following species were examined :— 
Amongst the green weeds Ulva lactuca (the sea lettuce) 
Huteromorph sp., and a very interesting form of Caulerpa, 
which appears to grow from a rhizome saatan attaches itself to 
rock or sand and acts as a holdfast. Of the brown weeds, 
Hormosira Banksii (the head seaweed) was found in abund- 
ance, also a kelp Ecklonia sp., and of the red weeds several 
species of Laurentia. 
On the hill a few flowering plants were collected, namely, 
Irachymene linearis, Dipodium punctatum, the snake orchid, a 
species of Goodenia, Westringia rosmariniformis, ithe coast 
rosemary, and Hypacris microphylla. 
Although there were only about fifteen members present, 
the excursion was an altogether interesting and successful one.

NOTES AND COMMENTS. 
At the April meeting, Mr. Cheel exhibited specimens of 
Burmannia disticha. It is chiefly found in the northern parts 
of the State, at Port Stephens, Byron Bay, Deepwater and 
Tweed River, extending into Queensland, Malay Archipelago 
and Bast India. .He also exhibited fruiting specimens of the 
so-called Blackfellow’s Bread (Polyporus mylittae). The spore- 
bearing pileus were well developed, of a whitish colour, with 
zones of egg-yellow colour.
