No. 19. Fossils from the Port Keats bore, thirty miles north of 
Fossil Head. After passing through what may be Mesozoic beds, 
fossils of Permo-Carboniferous or Carboniferous age were obtained, 
including two Foraminifera, several species of Polyzoa, a coral 
(Dybowshkiella), a Brachiopod (Chonetes), and leaves of Glossopteris ; 
the more important are described and figured. They comprise :— 
FORAMINIFERA. PoLyzoa. 
Nubecularia Stephensi, Howchin. Ramipora sp. 
Cornuspira tnvolvens, Reuss (?). Rhombopora Hindei, Eth., sp. nov. 
ACTINOZOA. Streblotrypa Browni, Eth., sp. nov. 
Dybowskiella Geei, Eth., sp. nov. 
Nos. 20, 21, and 22 deal with Cretaceous fossils from three 
localities, two of which are near Port Darwin. Plates are devoted 
to Ancyloceras, etc., though the genus is queried, and to Ammonites 
Rhotomagensis, which Mr. Etheridge says more resembles the British 
Chalk form than it does that from the Ootatoor group of Southern 
India. The species previously described from the Point Charles 
deposit (No. 20) and also obtained by Mr. H. Y. L. Brown and his 
party comprise :—Aucella incurva, Eth. fil.; Mucula seyugata, Eth. 
til.; Desmoceras carolensis, Eth. fil.; Histrichoceras antipodeus, Eth. 
fil.; Scaphites cruciformis, Eth. fil.; Crioceras (?) sp.; Hamites (?) sp. ; 
Ancyloceras (?); Belemnites sp. 
From No. 21, Shoal Bay, several of the same species of Cretaceous 
fossils were obtained, and in addition a specimen referred to the genus 
Baculites under the name of Baculites Williamsonz, Eth., sp. nov. 
At locality No. 22, Maclear Creek, Cape Gambier, Melville Island, 
the common form Jnoceramus Etheridgec was obtained, and an 
Ammonite (like our British form) named Jetacanthoplites Rhoto- 
magensis, Brongn. 
Plates iii and iv. Typical blocks of groups of <Avzeulopecten 
Hardmani have been prepared by process from excellent photographs 
by H. Barnes, jun. ‘The other ten plates are drawn by Frank R. 
Leggatt, and are very good so far as the specimens (many of which 
are very fragmentary) permit. 
We are greatly indebted to Mr. Robert Etheridge in this, as in his 
many earlier memoirs, in which he has so largely contributed to our 
knowledge of the paleontology of the older rocks on the Australian 
Continent.
