next in numerical force is 'Niihondaria, roli/morpliina, Bulimiiia, and Lit/tola 
are represented by a few individuals. 
The anthers stated that nearly all the varieties of the Nodosarinm fonud at 
Chellaston are present in the Lias, in the elays of the Oolites, hi the Gault, 
Chalk-marl, Ciialk, some Tertiary deposits, and in some of the western Medi- 
terranean and other seas; and the species of the other genera have also per- 
sisted to the present day. One of the Triassic forms was described as a new 
variety under the name of vV. Tibia. After describing the distribution of 
Foraminifera in many of the Mesozoic strata, and jjointing out that Nodosariee, 
Tc.rtularifP, Rotulirr, and some other Foraminifera occur in the palaiozoic rocks, 
Messrs. Jones and Parker observed that altogether we have here some remark- 
able instances of the persistency of life-types among the lower animals. 
" Though the specific relationship of the palseozoic Foraminifera require further 
elucidation, we feel certain that the six genera represented in the Upper 
Keuper Clay of Chellaston by at least thirty varieties stand really in the place 
of ancestral representatives of certain existing Foraminifera, that they put on 
their several subspecific features in accordance with the conditions of their 
place of growth, just as their posterity now do, and that, although we have in 
this instance met with only the minute forms of a seven hundred fathoms mud- 
bottom, yet elsewhere the contemporaneous fuller development of these specific 
types may be found by careful search in other and more shallow water deposits 
of the Triassic period."

"On the Physical Relations of the Reptiliferous Sandstone near Elgin. " 
By the Rev. W'. S. Symonds, F.G.S. 
Referring to Sir R. Murchison's sections of the Elgin district, in the Quart. 
Journ. Geol. Soc., No. 59, pp. 42i and 428, which show a conformable sequence 
of strata from the Old Red Sandstone of Foths to the yellow sandstone and 
cornstone of Lossiemouth and Burgh Head, the author stated that the sili- 
ceous marly rocks, or so-called " corustones" of Glassgreen, Linksfield, Spynie, 
Inverugie, and Lossiemouth are in reality very dissiraUar to the cornstones of 
Foths and Cothall. He then pointed out the improbability of the so -called 
corustones of Glassgreen continuing to dip north-westwardly under the sand- 
stone of the Quarry-wood Ridge, especially as near Linksfield it is seen to dip 
away from that ridge. Evidence also of a break in the strata at the Bishop 
Mill quarries was brought forward to show tliat tlie sandstone beneath this 
" cornstone" (presumed to be the Reptiliferous sandstone) is probably brought 
by a fault against the lower or Holoptychian sandstone, which latter towards 
Spynie was shown to be surmounted by the Reptiliferous sandstone, and this 
last conformably by a marly siliceous rock or so-called " cornstone." 
Beyond Spynie Loch, northward, the author supposed that another fault had 
again brought uj) the sandstone with Stagomlepis and Ilyperodapedon at Lossie- 
mouth. Beyond this a cornstone-like rock is again seen to cover the 
sandstone.
