Extract

Several of the tubes of this singular genus are exposed in section on the weathered (water-worn ?) surface of a piece of limestone. The tubes are of an elongate conical form, rather rapidly tapering, and straight or slightly curved, the longest about 10 lines; each contains several smaller tubes one within the other, the last of these little hollow cones being the chamber of habitation. The shell is thick, and has consequently not been crushed, two or three of the inner tubes retaining their cylindrical form, as seen in the section Fig. 1b.

The following is Mr. E. T. Hardman's classification of the rocks in this District:—

See his reports on the Geology of the Kimberley District, “Western Australia (Perth, W. A., 1884 and 1885; with lists of fossils, rocks, and minerals, maps and plates).

page 102 note 2 Mr. Kidston rejects Knorria, and says that “the plants for which it was formed are merely imperfectly preserved examples of Lepidodenion, and perhaps also individuals of other genera.” See Cat. Palæozoic Plants in Depart, of Geol. and Palæont., British Museum (Nat. Hist.), by K. Kidston, F.G.S., 1886, pp. 167, 174.

Soc. 1883, vol. xxxix. p. 582, where references to previous reports on the geology of this region may be found. The evidence afforded by the fossils of the Gascoyne River district (and those of a similar horizon from the Irwin River in the southern part of West Australia, and the Fitzroy River in the northern) is quite confirmatory of Mr Hudleston's views as to the age of the Australian Carboniferous, viz. that it corresponds with the Lower, rather than the Upper Carboniferous of other countries.
