A. H. Foord— Western Australian Fossils. 101 



known and widely distributed species of Blnjnclionella, viz. B. pugnus 

 (two varieties), and B. cuboides, both of which commence in the 

 Devonian, and pass up into the Carboniferous. These species occur 

 also at Rough Range, the significance of which fact will be recognized 

 farther on. The other fossils included in the Devonian consist of 

 species of Spirifera, Orthoceras, and Goniatites, all from Mount 

 Pierre, and although they cannot be specifically determined, their 

 occurrence in the same locality as the Rhynchonellas, and in a similar 

 matrix, warrants the conclusion that they belong to the same horizon. 



Mr. Hardnian notices the occurrence of Devonian fossils on the 

 Margaret River, a tributary of the Fitzroy, in his second " Report on 

 the Geology of the Kimberley District," 1885, p. 17, but he does 

 not say to what species they belong. The following is the passage 

 in his report to which I refer : — "The greater part of the limestone 

 in this region is very fossiliferous. In several places in Rough 

 Range, at Mt. Pierre, at Mt. Krauss, to the south of Hull Range, 

 and in the rocks opposite to that hill on the south side of the 

 Margaret, quantities of fossils of Carboniferous age were obtained, 

 including Sponges (Stromatopora) ; Corals of several varieties ; 

 Annelids, Spirorbis, and Serpula? ; Polyzoa, Brachiopods ; Lamelli- 

 branchs ; Gasteropods, and Cephalopods. A few of these fossils are 

 characteristic of the Devonian rocks, while others with which they 

 are associated are as distinctly Carboniferous. This would denote, 

 therefore, that these limestones belong to the Lower Carboniferous 

 period, as it is not uncommon to find beds in the Lower Carboniferous, 

 where fossils peculiar to both these formations intermingle to some 

 slight extent ; as, for instance, in the Lower Carboniferous rocks of 

 Ireland, where in the county Cork true Devonian fossils are found 

 along with the more characteristic Carboniferous fossils." 



It would have been more sat.isfactoi-y had Mr. Hardman given the 

 names of the Devonian species which he alleges to have been found 

 intermingled with Lower Carboniferous ones in the Kimberley 

 District. This he has not done. But besides the evidence of the 

 existence of Devonian rocks in this region supplied by such a 

 characteristic species as Atnjpa reticularis, there is that afforded by 

 the Stromatoporoids from Rough Range, to be described in a forth- 

 coming paper by Dr. H. Alleyne Nicholson, who finds that they are 

 of Middle Devonian age.

Two variations of this species occur in the Collection. One 

 (Fig. 2) resembles the tumid forms figured by Davidson in his 

 British Carboniferous Brachiopoda (pi. xxii.), the other (Fig. 2a), 

 the flatter and broader forms (var. anisodovta), figured on plate xii. 

 fig. 12 of that author's British Devonian Brachiopoda. 



Locality. — Mt. Pierre, near the Fitzroy River, Kimberley District.
