Akt. XVI. — A New Aininonlte from the Cretaceous 

 Rocks of Queensland. 



By Professor J. W. GREGORY and F. VOSS SMITH. 



[Eead 9th October, 1902.] 



(With Phxte XXII.). 



The Animonite described in this paper was found by one of us 

 in the Bourke Museum at Beechworth, where it was labelled 

 simply from the " Mitchell River." It was as.sociated with 

 specimens from Gippsland, and under the impression that the 

 Victorian JSIitchell River was intended, the specimen was 

 borrowed by kind permission of the Trustees of the Beechworth 

 Museum. 



The sutures were carefully developed by Mr. H. J. Grayson, 

 and its approximate geological position was thus determinable. 

 Its affinities were clearly cretaceous, but no rocks of cretaceous 

 age were known from Victoria. 



It was subsequently suggested by Mr. T. S. Hall that the speci- 

 men probably came from the Mitchell River of Queensland. It 

 agrees fairly well in its matrix with specimens which we have 

 seen from that area ; and there can be little doubt that its 

 locality has been correctly, though indefinitely, recorded. The 

 specimen is of interest owing to the exceptional perfection with 

 which the complicated sutures are shown. As some time had 

 already been spent upon the specimen and we devoted further 

 study to it after our return from Lake Eyre, when our attention 

 had been directed to the Cretaceous fauna of that area, we now 

 describe it. 



We are much indebted to the Trustees of the Bourke Museum 

 for their long loan of the specimen, and to Mr. Grayson for the 

 skill with which he cleaned the suture lines.
