Secretary, dated “Darling Downs, 1st October, 1853.” 
If this generic name had had priority of the one given by me to the same extinc 
genus, it must have been suppressed, since Sclmodm had been previously applied in 
1829 -to a genus of fishes, which still retains it, by Agassiz § ; to a genus of mammals 
by Mr. Wateehouse, in 1842 ; and, slightly modified as Schzodus, to ^ ° 
lusks by Mr. King. Of course the two latter applications, like that by Mr. MiT 
BUEY must fall into the subordinate rank of synonyms. ^ 
The additional fossil of the ThylaeoUo discovered by Mr. Stutchbuet is a very wel- 
come one. It was not, indeed, sufficient to guide the Colonial geologist to an idea of 
the order oi Mammalia to which it belonged; and Mr. Stutchbuey concludepns bnct 
notice of the fossil by the remark, “ Its affinities had better be left for future discussim.
