CARBONIFEROUS.

from those of our own Yorkshire limestone. And this list 
was lately extended and improved by the labours of Mr. Tlios. 
Davidson, who re-described, in the Journal of the Gcol. So¬ 
ciety for 18G1, all the species brought home by Fleming, to¬ 
gether with another collection made in the same range more 
recently by Mr. Purdon. 
In this useful paper Mr. Davidson enumerates no less than 
28 species of Brachiopodous shells alone, and 13 of these are 
indentical with British fossils. 
With these, however, are of course many forms not known 
in our own area. Prof. King described from Dr. Gerard's col¬ 
lection a fine species of Strop/ialosia, S. Gerardi* a genus more 
commonly known in Permian rocks. And in the carboniferous 
limestone of the salt range, more than one species of Ceratites 
is found. These exceptions may be explained by-and-by, when 
a more minute examination of the rocks shall be completed. 
The collection of carboniferous species made by Colonel Stra- 
chey is not a large one; and it is to be observed, that the fossils 
are found in loose blocks, in the Chorhoti Pass, in a locality 
filled with silurian slate. Colonel Stracliey, however, states 
there are great faults in this series of rocks, some of which 
may probably have brought down carboniferous strata from a 
higher level. There is no such ambiguity in the Spiti section. 
The following species were collected from a blackish arena¬ 
ceous limestone. As they have, with two exceptions, been be¬ 
fore fully described, I do not think it necessary to waste type 
and paper by giving fresh descriptions. Some are too imper¬ 
fect even to name.
