328 Reports and Proceedings— 
Monsieur Harlé’s paper on the cavern and other Pleistocene 
deposits in south-west France, comprises several short notes read at 
different dates. The Megaceros (Cervus giganteus) is recorded from 
many localities, but merely on the evidence of jaws, no antlers 
having been observed. The Beaver only occurs rarely, and very 
few remains are earlier than the ‘ Magdalenian” period. The 
common Cave Hyzena is met with abundantly; but M. Harlé has 
been unable to recognize the Striped Hyzena. Remains of the Saiga 
Antelope are known from twelve localities. The rodents comprise 
lemmings, marmots, and Alactaga jaculus, Pall. — typical steppe- 
animals. On the whole, the region north of the Garonne appears 
to have been a great steppe in the “ Solutrian”’ and “ Magdalenian ” 
periods, becoming more humid before the last-named stage of human 
civilization had passed away. A. S. W.

HESE are preliminary notes on some Mammalian bones from 
Ulloma in Bolivia. An equine mandibular ramus is referred 
to Hippidion nanum, Burm., and another is believed to represent 
a new species of the same genus. The remains of Mastodon, 
Megatherium, and Scelidotherium (?) are briefly discussed, with 
three plates of outline figures.

J.—May 10th, 1893:—W. H. Hudleston, Esq., M.A., F.R.S., 
President, in the Chair. The following communications were read : 
2. “The Llandovery and Associated Rocks of the Neighbourhood 
of Corwen.” By Philip Lake, Esq., M.A., F.G.8., and Theo. T. 
Groom, Esq., B.Sc., F.G.S. 
The area described forms part of the northern slope of the 
Berwyn Hills, and stretches along the southern bank of the Dee 
from Corwen to Pen-y-glog. The beds of the Berwyns are here 
thrown into a series of folds which run nearly H.-W.; and the 
northerly limbs of these folds are long and low, while the southerly 
limbs are short and steep. The folds are cut through by a number 
of faults which run nearly E.—W., generally along the crests of the 
anticlinals, and these invariably throw down towards the north. 
The southern bank of the Dee Valley is here formed by these faults. 
A second series of faults running about 20° W. of N. to 20° H. of 
S. is of later date. One of these, near Corwen, presents some 
peculiar features, since its downthrow in some places is on the east 
and in others on the west. 
The lowest beds present are bluish slates with numerous Bala 
fossils. These are succeeded immediately by the Corwen Grit of
