ANNIVERSARY ADDRESS OF THE PRESIDENT. XCI 



he notices the fossihferous beds of Dmas Cove, containing Turh'ino- 

 lopsis celtica and Encrinites, and of Permizen Bay, in which Turbi- 

 7iolopsis celtica, and another coral, Crinoidea, Spirifera, and Ortho- 

 ceras ludense (common) are found. He further mentions the 

 greenstone and associated rocks of Trevose Head ; the fossihferous 

 beds of Bodruthan Steps, where among other remains those of a trilo- 

 bite are discovered; the quartzose rocks of St.Eval chffs; the discovery 

 cf a Spirifer near Trevarrian ; the variegated slates, cut by a great north 

 and south elvan, of Watergate Bay, these variegated beds resting upon 

 the greenish and brown slate, with limestones, of St. Columb Forth, 

 in which Mr. Pattison found Turbinolopsis and another coral, pro- 

 bably Favosites, Crinoidea, Spirifera {S. disjunct a and another), 

 Orthoceras ludense, a Goniatite and a Calymene. He states that, 

 nearing New Quay, a hard blue calcareous rock contained Favosites, 

 C)rthis or Terebratula, and numerous remains of Encrinites. In the 

 fine raised beach at New Quay Mr. Pattison detected the remains of 

 shells, determined by Mr. Couch as those of Modiola vulgaris, Cy- 

 therea chione, and of a Patella and Ostrea, all molluscs now living in 

 the adjoining sea. Crinoidea were found in the brown sandstones 

 and slates of East Pentire Point. 



In a notice of the trap veins and limestone rocks of Towan Head, 

 St. Columb Minor, Mr. Tweedy describes and gives a map of that 

 interesting point of land, where fossihferous argillaceous slate and 

 calcareous beds, one worked for limestone, are traversed by numerous 

 veins of trappean rocks. He notices nhie or ten of these veins as 

 occurring in one locality within a distance of fifty feet, the igneous 

 rock of some dykes being vesicular. 



]Mr. Peach has again added to his lists of Cornish fossils in a paper 

 " On the Fossihferous Strata of part of the South-east coast of Corn- 

 wall." He mentions additional specimens of Onchus, supposed to be 

 O. Murchisoni, from Lantivet Bay, as also a portion of an Astero- 

 lepis. He traces the fish-beds from near Pencarra Point, by Trega- 

 brown Hill, ^^ith strata termed Bellerophon-beds, across Fowey Har- 

 bour. Quartzose strata and claret-coloured slates accompany these 

 beds. Detailed accounts are given of the localities in which the fish 

 remains have been discovered. Hard rocks, intermingled with soft 

 red sandstones, some brown beds and thin layers of impure limestone, 

 run from Lantick Bay across to White Horse Ferry, and contain 

 corals, crinoidea, orthoceratites, large shells and trilobites, the latter 

 rare. In the slaty beds, seaward from Black Bottle, Lantick Bay, 

 large corals are detected, and in thin seams of impure limestones cri- 

 noidea, large Turbinolopsides and shells are abundant. A fine speci- 

 men of a trilobite is described and figured, from Punch's Cross. Mr. 

 Peach mentions the surface- markings, commonly termed ripple- 

 marks, of some localities, and thinks that the marks upon one bed- 

 surface, from Highgate quarry, St. Veep, may have been due to the 

 effects of rain, as has been supposed the case \^ith certain surface- 

 markings in the new^ red sandstone of Lancashire. 



In a paper " On an insulated patch of Devonian strata in the parisli 

 of St. Stephen's by Launceston, Cornwall," Mr. Pattison describes
