the peculiar absence of animal-remains in these deposits, often rich 

 with vegetable-remains, concluded the paper, which was illustrated 

 by several original plans, sections, and sketches. 



2. "* On two Volcanic Cones at the Base of Etna." By Signor 

 G. G. Gemmellaro. 



These two cones occur at Paterno and Motta (Sta. Anastasia) ; 

 and the existing remains of their craters and nuclei were described 

 in detail. The author concludes that these were two contempora- 

 neous doleritic volcanic cones, that w r ere formed in the Post-pliocene 

 period, previous to the deposition of the calcareous tuff of the vici- 

 nity of Paterno, — also that they were cones of eruption, and not of 

 elevation, for the neighbouring strata are not disturbed — and that 

 they were independent eruptions, and not parasitical cones of Etna. 



3. '* On some Fossil Brachiopoda of the Carboniferous Rocks 

 of the Punjab and Kashmir, collected by A. Fleming, M.D., &c, 

 and W. Purdon, Esq., F.G.S." By T. Davidson, Esq., F.R.S., 

 F.G.S. 



Dr. Fleming's geological researches on the Salt-range and else- 

 where in the Punjab, in 1842-52, are recorded in the Journal of 

 the Society for 1853, in the Journ. Bengal Asiat. Soc. 1853, and in 

 his Report on the Salt-range, 1854. The species of Carboniferous 

 Brachiopoda collected by Dr. Fleming and described and figured by 

 Mr. Davidson, are Terebratula (vel Waldheimia) Flemingii, Dav., T. 

 problematica, Dav., T. subvesicularis, Dav., Retzia radialis, var. 

 grandicosta, Dav., Athyris Royssii, L'Ev., A. (vel Merista) subtilita, 

 Hall, var. grandis, Dav., Spirifera striata, Martin, Spiriferina octo- 

 plicata, Sow., Orthis resupinaia, Martin, Streptoraynchus crenistria, 

 Phil., var. robustus, Hall, St. pectiniformis, Dav., Productus striatus, 

 Fisch., P. longispinus , Sow., P. contortus, Sow. 



Mr. Purdon's collection comprises, besides several of the fore- 

 going, Terebratula Himalaye?isis, Dav., Spirifera Moosakailensis, 

 Dav., Sp. lineata, Martin, var., Camarophoria Purdonii, Dav., Pro- 

 ductus Purdonii, Dav., P. Humboldtii, D'Orb., Aulosteges Dalhousii, 

 Dav., and Strophalosia Morrisiana (?), King, var.

The following communication was read : — 



" On the Bracklesham Beds of the Isle of Wight Basin." By the 

 Rev. O. Fisher, M.A., F.G.S. 



After noticing the researches of Prestwich and Dixon, the author 

 proceeded to state that most of the " Bracklesham Beds " are dis- 

 played at low water at Bracklesham Bay ; but other and higher beds 

 belonging to the same series are to be observed in the New Forest, 

 at Stubbington, and in the Isle of Wight. By means of the fossils, 

 for the most part, Mr. Fisher divides the series into four groups : — 

 A. The uppermost abounds in Gasteropoda, and has several fossil- 

 beds. One of these, in the eastern part of its range, is full of Num-
