tliis respect approaches more nearly to that oi' tlie 
country round Hydney than to that of Brisbane. ll is 
notable tlie number of species- fn ('oleoptera which are- 
identical from Hydney forms, and not found about Bris- 
bane. A^ain, in Lepidoptera are many species confined 
to the Island, as also is tlu^ cast* in Hyiuenoptera, Ncur- 
0])1era. Diptera, etc. Tliere at-e certainly numbers of 
insects wliich ai*e etpially at liome on tiu* Island as on 
the adjacent mainland. 
'rin' explanation of the similarity of forms to those- 
of Sydney may ])erhaps be found in the soil and vegeta- 
tion of tlie Island ])eing of somewhat like character to 
that around that city. 
A fact Avorthy of nott* about tliis excursion was 
the alnu)st entire freedom from the worry of mosquitoes. 
Neitiier ])y day nor by nigh! were we troubled by these 
dijdcrous plagues. Miglit it not be well for our city 
fathers I0 enquiia* into this remarkable scarcity of these 
insf'cts in a plnee wiiei’c we were surrounded by 
swamjis, usually considered as fine bi’eeding oTOunds. 
Perhaps they had all departed for Dunwieh, where tlie 
dengue was said to be preAuilent. 
Another matter that requiri's attention is that the 
placards as to sanctuary are openly set at defiance by 
young men as to shooting. One sturdy fellow I saw 
eomine ashore with a gun. and a lot of boys follpwing 
him. 1 warned them, and i>lain!y told tliem I should 
consider it a duty to reiiort the matter. Tliey simply 
defied mt*. This Avas close to our camp at (^ne "Mile,

GEOLOGICAL NOTES ON THE EASTER 
EXCURSION. 
(By Dr. E. O. Marks, President.) 
^loj'eton and Stradbroke Islands, consisting almost 
entirely of sand dunes, do not offer a Avide seojie for the 
study of ‘bsolid” geology. Indeed, it is only in four 
very limited areas (one on Moreton and three on Strad- 
bi*oke) lliat any rock is known I0 be expost'd. Never- 
theless. our last tliree Easter excursions have resulted in 
'■.op t, useful contributions to tiie geology of these' islands.

geological surpi'ise*. in linding that lieadland to co^isi.st
