The R502 series of maps has been replaced by the National Topographic Map Series (NTMS). The R502 series consists of 542 map sheets and covers Australia at a scale of 1:250,000. It was compiled from aerial photography, but only about one quarter of the series was contoured. The standard sheet size is 1 degree of latitude by 1.5 degrees of longitude. Transverse Mercator map projection and Clark 1858 datum were used. Coverage of the country was completed in 1968.

The Bulletin describes and figures Bryozoa collected from three Permian formations in the West Kimberley district of Western Australia: the Nura Nura member of the Poole Sandstone, the Noonkanbah Formation, and the lower part of the Liveringa Group. Seventy-nine species are recorded. Forty-two of them are new species; and three new genera (Evactinostella, Etherella, and Liguloclerna) and a new family have been erected in the Cyclostomata. The facies relationships of the species show that habitat is an important factor in correlation. Ramose zoaria appear to be more adaptable than other forms, and some species are almost ubiquitous. The Nura Nura fauna may be correlated with the Callytharra Limestone of the Carnarvon Basin and possibly with the Lower Productus Limestone of the Salt Range of India. Many of the Nura Nura species are long-ranging. The Noonkanbah species are, on the whole, more restricted: they can be correlated, within Australia, with the Wandagee Formation and Baker Formation of the Carnarvon Basin. Outside Australia, the fauna shows resemblances to those of the Bitaoeni and Basleo Beds of Timor and an Artinskian fauna from Vancouver Island; some Fenestel1idae resemble Lower Permian species described from the Urals.
