lose much of its force if this Ci/rena were proved to belong also to the newer 
geological horizon. The question is now the more important, as this shell has 
been found by Mr. Prestwich in the beds that contain flint implements at 
Abbeville. 
The author proceeded to show that some gravels and sands near Hull in 
Yorkshire, formerly described by Professor Phillips, contain abundance of the 
Ci/reua JUminalh, associated with twenty-two species of marine shells, two of 
which have Arctic characters, the others being common littoral forms. These 
gravels and sands were proved, by well sections and other ex])Osures, especially 
by borings and trenches made by the autlior and Mr. T. J. Smith, F.G.S., of 
Hull, to overlie the Boulder-clav.

1. "Description of two Bone-caves in the ^Mountain of Ker, at Massat, 
in the Department of the Arriege." By M. Alfred Foutoau. Communicated 
by M. E. Lartet, For. Mem. G. S. 
"^The valley of Massat, on the northern side of the Pyrenees, is of triangular 
shape, its northern angle being narrowed by the projecting limestone mountain 
of Ker. Among the fissures and grottos that traverse this mountain in every 
direction are two caves in particular ; one is situated near the top, at about 
100 metres above the valley; the other is near the base, at about 20 metres 
above the river. They both open towards the north. In the upper cave M. 
Fontan found a sandy loam with pebbles (the pebbles being of rocks different 
from that of the mountain), extending inwards for 100 metres, and containing 
a large quantity of bones of Carnivora, liuminantia, and Rodentia; those of the 
great Cave-bear, a large Hycena, and a large Felis being the most numerous. 
On the surface some fragments of pottery, an iron poiguard, and two Roman 
coins were found, with a quantity of cinders and charcoal ; and at a depth of 
more than three feet in the ossiferous loam another bed of cinders and charcoal 
was met with, and in this M. Fontan found a bone arrow-head and two human 
teeth ; the latter were at a distance of five or six metres one from the other. 
In the lower cavern a blackish earth, with large granitic and other pebbles, 
was found to contain bones of the Red-deer, Antelope, Aurochs, and Lynx ; 
also worked flints and numerous utensils of bone (of deer chiefly), such as 
bodkins and arrows ; the latter have grooves on their barbs, probably for 
poison. Some of the bones bear marks made of incisions by sharp instruments 
in flaying or cutting up the carcases. In each cavern a chasm crosses the gal- 
lery and terminates the deposits ; in the upper cave at 100 metres, in the lower 
one at about seven metres from the entrance. 
The author argues that, from the facts which he has noticed, these caverns 
must have been subjected simultaneously to the effects of a great transient 
diluvial cataclysm coming from the N.N.W. or West, in the opposite direction 
to the present course of the waters of that region; that man and all the other 
animals the remains of which are buried in these caves existed in the valley 
before this inundation ; and that the greater part of the animals inhabited the 
caves, but that man was not contemporary with all of them. 
2. "Notes on some further Discoveries of Flint Implements in the Drift; 
with a few suggestions for search elsewhere." By J. Prestwich, Esq., F.ll.S., 
Treas.G.S. 
Since the author's communication to the Royal Society last year on the 
discovery of Flint Implements in Pleistocene*^ beds at Abbeville, Amiens, 
and Hoxne, similar implements have been found in some new localities in this 
country. 
In Suffolk, between Icklingham and Mildenhall, Mr. Warren has met with 
some specimens in the gravel of Rampart Hill in the valley of the Lark. 
«This gravel is of later date than the Boulder-clay of the neighbourhood. In
