2. " Oil some Arrow-heads and otlicr Instruments found with Horns of 
Cervus megaceros, in a Cavern in Lauguedoc." By M. E. Lartct, Por. M.G.S. 
(In a letter to the President.) 
In a cavern of the limestone at Massat, near Tarascon in Languedoc (Depart- 
ment of Ariege), examined by M. A. Fontan, tlie floor was found to eonsist of 
a blackish earth, ^nth large rounded pebbles, among which were mixed, in great 
disorder, bones and Horns of a Chamois, Cervus liseudovirginicnnis, C. megaceros, 
and Bos, together with implements of stone and bone, to which MM. Isidore 
Geoifroy Saint-HUake and E. Lartct have referred to iii the ' Comptes Rendus' 
of May "10, 1858. 
M. E. Lartct in his letter, has furnished drawings and descriptions of some 
tarbcd arrow-heads of bone, some having indented grooves, jjrobably for the 
appliance of poison ; also needles, and a flute-bevelled tool of bone, a splinter 
or knife of hard flint, and the horn of an Antelope hacked at the base, probably 
when the animal was flayed. 
3. " On the occurrence of Crag Shells beneath the Boulder-elay in Aberdeen- 
shire." By T. E. Jamieson, Esq. Communicated by Sii- B. I. Mui-chisouj 
V.P.G.S. 
In a former paper (Q. J. G. S. vol. xiv., pp. 522-525) the author referred to 
the existence of gravelly beds containing marine shells underlying the boulder- 
clay between Coudeu and Slaius, on the coast of Aberdeenshire, over an area 
of about six miles by three and a half ; these sheUy sands and gravels he has 
since more carefvdly examined, and he refers them to the age of either the Red 
or the MammaUferous Crag of England. Ci/prina rustica, C. Islandica, 
Astarte, spp., Venus, spp., Artemis lincta, Cardium spp., Pecten opercularis, var. 
Audouini, P. maximus? , P. princepsF, Pectunculiis glijcimeris, Tellina 
solidula. My a truncata ? , Fusus antiqwus and its variety contrarius, Mangelia, 
Purpura lapillus, var. crispata, occur in worn fragments. Cyprina Islandica 
is the most abundant. 
Chalk-flints are common among the materials of tlie beds in question ; also 
fi-agments of fossiliferous limestone and of red aud grey sandstones, of undeter- 
mined age. 
4. " On some small fossil Vertebrce near Frome, Somersetshire." By Prof. 
Owen, F.R.S., E.G.S. 
In this communication Prof. Owen described three minute Vertebra; dis- 
covered by Charles Moore, Esq., E.G.S., in an agglomerate occupying a fissure 
of tlie Carboniferous Limestone, near Erome in Somersetshire, in company with 
teeth of a small Mammal allied to the Microlcstes of Plieninger. The vertebras 
are stated to correspond in size with the ictAhol Microlestes; but tohavcEeptflian 
characters, especially in their biconcave structure, — a character common iu 
Mesozoic Saurians, but rare in the existing genera. There appears to be but 
very shght grounds for supposing that such a character may have ever belonged 
to any Mammals, although some of the existing Monotremata have peculiar 
vertebral modifications somewhat resembling, in these respects, the structural 
features of Reptiles. In their large and aneliylosed neural arch, however, these 
little vertebra; present a mammalian character. 
Remains also of small Saurians and Eishes oeciir in considerable numbers 
■with the vertebra; iu question, as well as the more rare mammalian teeth.
