574 Miscellaneous. 
11. The same bone of 2 species of Perameles, without teeth, but 
showing nearly all the sutures. 
A conglomerate mass of bones and red gravel, after being broken 
with a hammer, was found to contain the first two molars of the 
lower jaw of a dog ; it is possible that this dog was similar to the 
Dingo of the present day. The left canine of the lower jaw of a 
dog was also obtained, besides six or seven fractured lower jaws of 
rodents, and portions of molar teeth of Diprotodon ; but the most 
curious and interesting tooth I ever beheld came out of the same 
mass. In shape it resembles the first of the premolar series of the 
lower jaw in man; the root, however, is much longer, the crown 
smaller, protruding, and considerably worn. The root is not smooth, 
as in man, but somewhat ridged, with a few tubercles on the upper 
part. I have no conjecture to offer as to which genus this 
tooth is referable; but as I have given Professor Owen a full 
description of it, with drawings and photographs, I hope to be able 
to lay the reply of the great anatomist before your readers at some 
future period. These are all the mammals (besides Hypsiprymni and 
Halmaturi) obtained from the Wellington caves ; there are bones 
of birds as well, but the pieces are too fragmentary to permit me to 
offer an opinion upon them at present. I should also wish to give 
a short account of the fossil remains from the Darling Downs, 
which are deposited in this museum, but will do so at another time ; 
and only state now that in the famous genus Thylacoleo, as pre- 
dicted by Professor Owen, the lower canine terminated the dental 
series, showing a great resemblance between the great Australian 
carnivore (?) and the diminutive marsupial discovered by Mr. 
Beccles, in the Purbeck formation of England. 
I mention this fact because it appears to me that many of your 
readers may not be aware that at some remote period marsupial 
forms inhabited Europe, placentals were in existence, and that there 
is no occasion to account for the presence of placentals in Australia 
in any other way than that they already existed in the times of — 
the gigantic Diprotodons and Nototheriwms. 
CoaL IN BRAZIL AND THE FALKLAND IsLAnps.—Professor 
Agassiz, with his staff, has been engaged in a careful survey of the 
district watered by the Amazon, and his opinion has also been ob- 
tained concerning the Coal-fields of Candiota. For some time past 
attention has been directed to the famous Coal-beds of Candiota, 
in the province of Rio Grande do Sol. The expectations of many 
are turned in that direction, as the most valued instance of the 
hidden wealth of Brazil. Mr. Plant has so far awakened or revived 
an interest in these things, that from time to time the topic has 
become a public one, and has been looked at as a field for commer- 
cial activity, and has been debated each time with growing interest 
in the Legislature. Mr. Plant, submitted to the examination of the 
Professor such fossils and geological illustrations of the province of 
Rio Grande do Sul as he supposed would be of interest, and would 
help to complete the collections which are being made for the United
