aijent access to the central canal. The substance of this has been removed, 
and on subsequent pressure being applied the stem shell has caved in more or 
less in a vertical direction. 
CYSTOIDEA. 
Ohs. — Evidence is entirely lacking of the jiresence of this Class in the 
Carboniferous and Permo-Carboniferous rocks, either of New South IVales, 
Queensland, or Western Australia. 
BLASTOIDEA. 
Ohs. — Blastoids have not been met with either in New South Wales 
or Western Australia, but the Gympie Series of Queensland has yielded three 
genera, comprising three species. The descriptions of these have so far not 
been published, but will appear in the work on “ The Geology and Paleon- 
tology of Queensland and New Guinea,” by Mr. R. L. Jack and the Writer. 
Tlie genus Mesohlastus has been provisionally used as the receptacle 
for a rather aberrant species described as M. ? australis, Eth. til but it is 
pointed out that a new genus may be required for its reception. A frag- 
mentary specimen, but nevertheless quite distinct from either of the other 
Australian Blastoids, is described as Granaiocrinus ? Wachsmullii, Eth. fil.,^ 
and, lastly, a peculiar form fulfilling most of the characters of Tricoelocrinus, 
is figured as T. ? Carpenieri? 
Siih-Kingdom — ANNULOSA. 
Section — A n arthro poda . 
C/ass— ANNELIDA. 
Ohs. — I am not aware that the shelly tubes of the Tubicola, or the 
horny jaws of the Errantia have been, so far, met with in our Permo-Carbon- 
iferous, although the latter are knoAvn from the Upper Silurian of New 
South W ales,'* * having been collected, with a large number of other interesting 
organisms, at Bowning by Mr. John Mitchell, of Narellan Public School.
