The animal had a head shield and a tail 
segment of tough material and a segmented body 
of loosely jointed armour. Usually these parts 
have fallen to pieces before preservation. The 
principal points in classification are the shape 
of the front portion of the head, the size of 
the genial angles, the number of segments of the 
thorax, the shape of the tail segment and any 
tail processes and their shape* Until a com¬ 
plete animal is found the various portions can¬ 
not be connected satisfactorily. The animal 
had small crawling legs and antennae but these 
are very seldom preserved. It takes some prac¬ 
tice to detect small fragments of trilobite tests 
in the very altered rock in which they are found 
but an unnatural smoothness in an otherwise rough 
sandstone is the first indication. Sometimes the 
markings of the tail segment look like the veins 
of a fossil leaf. 
CORRESPONDENCE . 
Mr. E.W.Cruickshank writes:- 
:: I saw last November a crow volplaning 
for several hundred yards. This surely 
is unusual as they always seem to work 
their passage. tJ 
DEVONPORT BRANCH. 
This Branch continues to make good progress. Last 
October Mr. Scott of the Launceston Museum, who 
was spending a holiday at Mersey Bluff, gave a 
most interesting talk, illustrated with a micros¬ 
cope, at West Bay. 
JUNIOR SECTION . 
The first meeting of the Juniors was held in the 
Tasmanian Museum on March 18th. The room was 
packed with Juniors and visitors who seemed to 
enjoy the three films of animal life in India, 
Africa, and Australia. Several new members 
joined. 
WILD FLOWER COMPETITION. 
Juniors are reminded that June 30th is the last 
day for sending in their collection of wild
