A few other beds much decomposed rest upon No. 6, and lime is 
stated to be apparently more plentiful in them. 
7. Above these the strata are more gritty, and fossils are rare, 
but the specimens obtained by the author include Atrypa aspera, = 
obscure traces of vegetable remains. 
8. Resting upon No. 7. is a shelly limestone, agreeing sisparlnult 
m dip and strike with the subjacent strata. The fossils are for the 
greater part the same as in the other beds, consisting of Producta 
depressa, Atrypa aspera, and a Spirifera which occurs also in No. 6. 
The rock near Dalhousie is a reddish slate, in which Mr. Henwood 
sought in vain for organic remains. ‘The dip of the laminz is 70° to 
the S.E. 
On the opposite side of the river in Lower Canada, the strata con- 
sist wholly of a brick-red sandstone. . 
Near Cambellton, both the Canadian and the New Brunswick 
banks of the Ristigouche are composed of sandstone and conglomerate 
with imperfect fragments of vegetable remains. The strata are cut 
through by numerous trap dykes, many of which have produced 
faults, but man equal number of instances no similar effects are 
visible. 
_At John Pratts, seven miles above Cambellton on the New Bruns- 
wick side of the Ristigouche, is a slaty limestone enclosing Crinoidea 
and a few other obscure organic bodies. The beds dip W., and strike 
20° E. of N. A thin-bedded limestone, in which the author could 
discover no fossils, extends to the Maramajaw, and thence to the Up- 
salguilch river. . In some places it is much traversed by trap dykes, 
and at the Little Falls of the Upsalguilch by dykes of felspar porphyry 
resembling the Cornish elvans. The strike of the strata is N. and 
S., and the dip W. 
3. “ Onthe locality and geological position of Cucullea decussata,” 
by Joshua Trimmer, Esq., GS: 
The object of this communication is to determine the geological 
formation to which the siliceous casts of the Cucullea decussata really 
belong, it having been stated that they occur at Faversham in Kent*,” 
m a bed of greenish siliceous sand, placed by Mr. Webster above the 
chalk+ ; in the upper greensand of Kent, but with a doubt}; in the 
lower greensand of Kent and Sussex, and in the greensand of Black- 
down §. 
The fossil was first described by Mr. Parkinson, who states, on the 
authority of the late Mr. Francis Crow, that it was found at Faver- 
sham associated with a silicified shell exactly agreeing with the Strom- 
bus pes Pelicani of the Devonshire whetstone pits; but he adds, that 
it is specifically different from the Cucullza of Devonshire, and he
