R. A. KEBLE,
Palaeontologist to the National Museum, Melbourne, and to
the Geological Survey of Victoria.
In 1902 the late Dr. T. S. Hall commented on the
graptolite records of Tasmania.
After weighing the
evidence regarding their reliability, he expressed a conviction
that Diplograptus sp. had been found at a locality given
by the finder, Mr. Thureau, as approximately 10 miles from Strahan, on the old Mt. Lyell Road close to an old road
maker's camp and stable near a spring of water.
Mr. P. B. Nye, Government Geologist of the Tasmanian
Geological Survey, has kindly submitted for re-examination
two of the slabs examined by Dr. Hall, sent to him by Mr.
Waller and now in the possession of the Survey, and Mr.
Clive Lord, Director of the Tasmanian Museum, Hobart, has
been good enough to add a third, i.e., that formerly in Mr.
Stephens's collection.
In regard to the Lisle graptolites, so called, Dr. Hall could
not do otherwise than regard the record as worthless, but as
he pointed out in a previous contribution Mr. Thureau
was familiar with graptolites and a skilled collector. He
discovered that elegant form Gonograptus thureaui, which
McCoy made a generic type, and added considerably to our
knowledge of the Lower Ordovician fauna
