plants having been found in the true Upper Sandstones and Shales 

 overlying the grey limestone. The author gave lists of fossil Plants 

 occurring in the two sets of strata, as well as of those occurring at 

 the separate localities ; and he concluded by describing some new 

 and some imperfectly known species of Ferns.

 sand." By H. Seeley, Esq., F.G.S. 



7. " On a new Crustacean from the Glasgow Coal-field.*' By 

 J. W. Salter, Esq., F.G.S. 



In a previous paper the author collected together what was 

 known of the Macrurous Crustaceans of the British Coal-fields. Since 

 then Mr, James Russell has discovered a new species, remarkable 

 on account of the antennules being larger than the antennae, and 

 which Mr. Salter now described in detail. 



8. " On the Occurrence of a Bituminous Substance near Mount- 

 gerald, Scotland." By Dr. G. Anderson. In a letter to Sir R. I. 

 Murchison, K.C.B., F.R.S., F.G.S., &c. 



The section exposed by some deep cuttings for the Ross-shire 

 Railway, two miles north of Dingwall, exhibits a grey micaceous 

 and almost horizontal conglomerate, traversed by fissures containing 

 a black bituminous substance, which the author stated might have 

 infiltrated down from a bed of bituminous schist which apparently 

 overlies the conglomerate. 



9. " On the Occurrence of Albertite at Mountgerald, Scotland." 

 By A. C. Mackenzie, Esq. 



In making a drain on a farm near Mountgerald, a fissure was dis- 

 covered which contained a bituminous substance very similar to the 

 Albertite of New Brunswick ; a deposit of a similar nature was also 

 discovered in making a cutting through " The Craig," near Mount- 

 gerald. The author described the stratigraphical and lithological 

 characters of the rocks met with in making this cutting, and stated 

 that thirty-six veins containing this mineral were passed through. 



10. " On the Occurrence of Rocks of Upper Cretaceous Age in 

 Eastern Bengal." By Dr. T. Oldham, F.R.S., F.G.S. 



During the years 1851—52 the author examined the rocks of the 

 Khasi Hills, in Eastern Bengal, and made a collection of the fossils 

 occurring there. These fossils were mostly from a Nummulitic 

 Limestone, and were evidently of Eocene date ; but some were 

 obtained from a sandstone underlying this limestone, and appeared 

 to be of Cretaceous rather than Tertiary age.
