lie was well versed in comparative anatomy, geology, and botany, 
although the two former claimed the preference in Ids attentions; 
but the writer of this sketch is largely indebted to him for nume¬ 
rous most interesting plants, collected by him during his various 
excursions at Port Phillip, as also for various botanical obser¬ 
vations on different districts of that colony . 
As one of the founders of the Tasmanian Society, and one of 
its most able and zealous members and supporters, his memory 
will be long and fondly cherished by all who pursue science in 
Australia. 
Read a paper “On the jaw of the Diprotodon Australis, and 
its dental formula.” By the late Dr. E. C. Hobson. It was 
accompanied by a beautiful drawing from the pencil of Mrs. 
Hobson. (Vide page 387 of the present number of the Tasma¬ 
nian Journal.) 
Read a letter from J. E. Calder, Esq., announcing that he had 
picked up on 28th February last, at Eagle Hawk Neck, (Pirates 
Bay side) twenty-nine specimens of Janthina fragilis , (common 
Oceanic Snail) with the animals in them. Mr. Calder’s letter was 
accompanied by specimens. 
C. S. Henty, Esq., exhibited numerous specimens of Bullaa 
aperta, Trigonia margaritacea, Clcidolharus, and other mollusks 
obtained by him at George Town. 
W. H. 13reton, Esq., exhibited a large suite of specimens of 
fossil wood, in the form of lignite, obtained in sinking a well about 
two miles north of Launceston, on the George Town road. Also 
the impression of a bivalve shell allied to Unio, and several seeds 
resembling those of an Acacia obtained from the same locality. 
Mr. R. C. Gunn mentioned that Joseph Milligan, Esq. had 
recently informed him that he had seen a turtle washed upon the 
eastern shore of Flinders’ Island, Bass’s Strait, and that he had 
also heard of turtles washed ashore on the eastern coast of Van 
Diemen’s Land. 
Mr. Gunn exhibited a beautiful specimen of a Trilohite received 
from Mrs. E. C. Hobson. It is only the posterior portion, and 
measures 1 8-10th inch in length, and 1 2-10 inch broad in the 
broadest part. It was found about 25 miles up the river Yarra, 
Port Phillip, embedded in an argillaceous rock, and is apparently 
of the genus Asaphus? 
Numerous specimens of a rolled matted fibrous substance 
washed upon the beach at the Great Forrestier River, north coast 
of Tasmania, were exhibited by Mr. Gunn. The masses varied 
in size from one inch to five or six inches in length, by about half 
an inch to an inch in diameter, tapering off at both ends. Mr. 
Gunn expressed an opinion that they were formed from the fibres 
of decayed or decomposing leaves of Zostera marina matted and 
rolled together by the action of the sea. Several beds of sea¬ 
weed embedded below the level of high water occur in that locality.
