104 A. R. Foord — Western Australian Fossils, 



Length H inches; height \ (H ?) inches ; distance of larger costas 

 at lower margin of valve, about -f- line. Apical angle, ears excluded, 

 slightly exceeding a right angle." 



This description agrees so well with the specimen in Mr. Hardrnan's 

 Collection that there is no doubt about its belonging to Dana's species. 

 It must be remarked, however, that in his previous description of 

 A. tenuicollis, Dana states that the costa? are about twenty-four. In 

 the specimen before me they number about twenty-six. The shell 

 is the convex valve, as was also Dana's. The latter was obtained at 

 Harper's Hill, New South Wales, in a sandstone. 



Locality. — Liverynga, Kimberley District, in a yellowish ferru- 

 ginous sandstone. 



GASTEROPODA. 

 Euomphalus ? ? PI. IV. Fig. 9. 



This specimen is far too much damaged by weathering to afford 

 any certain indication of its affinities. 



Locality. — " Opposite Mt. Krauss," King Leopold Kanges, 

 Kimberley District. 



Pleurotomaria ? ? PI. IV. Figs. 10, 10a. 

 This fossil is in the same condition as the above ; such of its 

 characters as are preserved are well represented in the figure. It 

 may belong to one of the subsections of Pleurotomaria. 



Locality. — " Opposite Mt. Krauss," King Leopold Eanges,

This species is represented by two small and imperfect examples 

 in a yellowish ferruginous sandstone. They are both casts, and show 

 no trace of septation.

This group is represented by numerous weathered fragments of 

 Crinoid stems, some loose, some imbedded in a limestone matrix. 

 They have been examined by Mr. F. A. Bather, F.G.S., of the
