172 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Jan. 8, 



The interesting Cycads derived from these beds, some of which 

 have been described by Mr. Garruthers (vide Trans. Linn. Soc xxvi. 

 1870, p. 675, pis. 54 & 63) are, like the other vegetables found in 

 the rock, evidently drift timber, which after long floating in the open 

 sea, and being subjected to the borings of numerous marine creatures, 

 became at last buried and fossilized. 



Above the Clynlish quarries, where the beds dip N.E. at an angle 

 of from 8° to 9°, various beds of stone, without shells, but with 

 much wood and carbonaceous matter, occur. A pit in these estuarine 

 sandstones, which are evidently the same with those exposed in the 

 gorge of the Brora, is open in Braamberry-Hill Wood ; and formerly 

 some of the harder and coarser beds were quarried for millstones. 

 In one of the small openings in the beds of sandstone capping 

 Braamberry Hill (of which a number were opened in order to test 

 the suitability of the ground for a cemetery), stone with casts of 

 shells was exposed, belonging probably to one of the marine bands 

 of the series. 



The lower part of the same great series of marine and estuarine 

 sandstones is exposed, though not very favourably for examination, 

 in the reefs at Brora Point. 



Near Uppat the same series of sandstones is developed. Some 

 of the pits and roadside sections expose only unfossiliferous sand- 

 stones with seams of carbonaceous matter ; but in a small pit in the 

 woods near Uppat House, I collected

 Wood. 



In the deer-forest above Dunrobin Castle, and at an elevation of 

 upwards of 500 feet above the sea-level, several small openings in 

 the wood expose the same series of sandstones. In a pit situated 

 due north of the Castle, to which I was first directed by my friend 

 Mr. Joass, the following species were obtained : — 



Ammonites cordatus, Sow. 

 Belemnites sulcatus, Mill. 

 Troclius, sp. 

 Pecten vagans, Sow. 



, sp. 



Pinna laneeolata, Sow. 

 Avicula braamburiensis, Sow. 

 , sp. 



Modiola bipartita, Sow. 



Gervillia. 



Lucina (crassa, Sow., pars). (Very 



abundant.) 

 Astarte. 



Gonioinya v-scripta, Sow., sp. 

 Gresslya, sp. 



Another small pit, a little to the north of the last, exposes other 

 white sandstones with a few casts of fossils, including 



Chemnitzia, sp. 

 Pecten fibrosus, Sow. 

 vagans, Sow. 



Perna, sp. 

 Lucina, sp. 



and other bivalves in casts, the species being indeterminable. 



Below these sandstone strata, which are also exposed in some
