V. — Etheridge, R., "A Supplement to Parliamentary Papers," No. 158, 

 1891, and No. 23, 1892, pp. 1-7, pi. i., 1893, adds Asaphus illareusis, OrtJwceras 

 gossei, O. tatei, Eiidoceras ^varhiirtoni and Ophileta gilesi. 



VI. — Etheridge, R., in " Annual Report of the Government Geologist," 

 Pari. Paper, No. 25, 1894, pp, 23-26, pi. iii., figures and describes a third species 

 of Asaphus, A. {Megalaspis) howchitii, and indicates by figures the occurrence of 

 three species of univalves belonging to uncertain genera, and one of Cteiwdoiifa, 

 besides some supplementary information regarding some previously-described 

 species. 



2. Fossil Localities. 



As already stated, atife p. 56, the fossils occur at one definite horizon in 

 the main mass of the Laparatine series, embracing shelly limestones and the 

 innnediately underlying sandstones and quartzites. The fossiliferous limestones 

 were observed in Ilpilla Gorge, Middle Valley (from near tlie junction of tlio 

 Walker and Palmer Rivers to Shakes Plain), between Petermann Creek and 

 Tempe Downs, Petermann Creek, north-east side of Gill's Range, by camp on 

 Laurie's Creek, and about four miles north (north of Tempe Vale). These locali- 

 ties are on two lines of outcrop of the same beds. Still further north, the same 

 series occupies the lowest level of Horn Valley from Mereenie Bluff to Finke 

 Gorge. The quartzites and sandstone subordinate to the fossiliferous limestones 

 yielded fossils at Middle Valley, Tempe Downs, between Petermann Creek and 

 Tempe Downs, north of Tempe Vale, and Horn Valley at Finke Gorge. Quartz- 

 iferous sandstone and limestones of Chandler's Range are fossiliferous, as also the 

 cjuartzitos of the Mount Watt outlier. The species of the limestones and of the 

 quartzites are distinct, with the exception of Orthis dichotomalis and Asaphus 

 thortitoni.
