and yellowish-grey colours, and well stratified. They contain thin leaf: 
beds at several different levels, whi¢h are prominent from their grey- 
purple tint; but though containing very many dicotyledonous and 
flag-like leaves, from their soft and crumbling nature, they do not yield 
determinable specimens. 
225. This part of the section also includes at least three lignite beds. 
The highest of these is about 140 feet above the base of the section, and 
three feet or more in thickness. It would appear to be of fair quality, 
though much decomposed and quite crumbling at the out-crop, from the 
action of the weather. The next is about 120 feet above the same datum, 
and can be traced a very considerable distance along the face of the bank. 
It is five feet in thickness, but includes, where examined, several thin 
layers of carbonaceous shale ; and, though of good quality in places, does 
not appear to have the same uniformity in the various layers that is 
generally found in the coals of this region. The lowest lignite is some 
seventy-five feet above the base of the section, and is only a few inches in 
thickness. 
226. The complete section may be thus represented :—

227. In certain parts of the upper portion of this section, the 
remains of Mollusca occur in some abundance, but in a very bad state of 
preservation. By diligent search, however, some specimens of Melania 
Nebrascensis were obtained; and also of a peculiar angular Paludina of
