the Geological Society, where they were inspected by him at my 
request, and noticed one (the one) which he considered to be very 
like L. tetraqohiW. 
During the last few years I have collected or received this 
plant from a variety of localities in New South Wales and 
Queensland, and from the latter Colony it was also brought in 
abundance by Mr. Daintree. Mr. Camithers, who has given its 
description fully in the paper before alluded to (Q.J.G.S., Aug., 
1872), has assigned tv it the name of a species described by 
Unger, viz., Lejndodendron nothum. 
The extent of territory from which my specimens have been 
collected embraces a direct distance of more than 1,100 miles 
(English) between 10° s. and 35° s. (of course at intervals only), 
from which we may infer the importance of its discovery in any 
new locality, as establishing the existence of a portion of the 
Devonian series to which it has been finally assigned. 
It was satisfactory to be able to recognize this plant in January, 
1875, in a creek near Rydal, on a spur of the Mount Lambic 
Range, where the Devonian Brachiopoda occur, and to be able to 
direct Mr. Wilkinson to the locality where he found his five 
additional specimens, which certainly established the position in 
situ of the species near that locality. 
But it was not until subsequent visits in 1870 and 1S77 that 1 
was enabled to detect the plant actually in situ , and which 
enabled me to ascertain the proper position of its habitat, which 
is considerably below the level of the Brachiopod sandstone 
of Mount Lambic, and on a spur of that range overlooking 
Solitary Creek. As a guide to future explorers, I left a “broad 
arrow” mark on the fence nearest the spot. 
Professor M‘Coy adheres to his first opinion that the plant is 
not L. no/hum (See “ Coal Report," and Decade 1 , “ Rrodomus of 
the Geology of Victoria ,”—pi. ix), and calls it L. Australe. 
Writing in 1SG1, the learned Professor proves that there is no 
mistake about the identity of the plant in question ; for he says, 
a specimen of it, still 1 believe in the Melbourne Museum, is of 
the same species as the only Ralccozoic Coal-plant ever collected 
in [New South Wales, and which was sent to him about twelve 
years ago for “determination during the controversy ns to the age 
of the plant-beds of the Newcastle N.S.AV. beds.” This mistake 
as to date is of no importance, as it is rectified by my previous 
quotation from Mr. M‘Coy’s letter, and I only refer to it to 
show, which is due to himself, that we are treating of the same 
plant. 
But there may be found many, and there are already known in 
New South Wales several distinct species of Lcpidodcndron and 
its allies, in the Lower Coal-beds along the Kama Basin and else-
