question whether or not the intervening beds have ever existed in 

 this locality, and came to the conclusion that they probably existed, 

 and have been swept away by denudation. He remarked further 

 upon the resemblance in lithological characters of the beds described 

 to the corresponding deposits elsewhere in Britain. The trap- 

 rocks intruded between the Jurassic deposits he regarded as of post- 

 oolitic date. The paper was accompanied by lists of fossils and 

 descriptions of some new species prepared by Mr. Ealph Tate. 



2. " Observations on the more remarkable Boulders of the North- 

 west of England and the Welsh Borders." By D. Mackintosh, 

 Esq., F.G.S. 



In this paper the author described the situation and indicated the 

 probable origin of many of the more striking known boulders in 

 Westmoreland, Cumberland, Lancashire, Cheshire, and on the bor- 

 ders of Wales. The northern boulders seem to have originated 

 chiefly from Wastdale Crag, Criffel, Ennerdale, and Eskdale ; those 

 of Cheshire chiefly from the Lake district and south of Scotland ; 

 and many of those on the Welsh borders from the mountains of 

 Wales. Many of the boulders noticed by the author exhibit glacial 

 striae. The author also especially referred to the occurrence of 

 boulders at high levels.

1. " Note on some Brachiopoda collected by Mr. Judd from the 

 Jurassic Deposits of the East Coast of Scotland." By Thomas David- 

 son, Esq., E.R.S., E.G.S. 



In this note the author stated that four species of Brachiopoda 

 collected by Mr. Judd were especially worthy of notice, two of them 

 being quite new, and two new to Britain. Three of them were ob- 

 tained from the equivalent of the Kimmeridge Clay, which was 

 the more remarkable as the Brachiopoda of that formation are 

 comparatively few. The new species described were Ehynchonella 

 Sutherlandi and Terebratula Joassi, derived, with Terebratula hume- 

 ralis, Bom., from the Upper Oolite of Garty in Sutherland; the 

 fourth species is Terebratula bisujfarcinata, Schlot., from the Lower 

 Calcareous Grit of Braamberry Hill. This note is intended to form 

 an appendix to Mr. Judd's paper on the Secondary rocks of the east 

 coast of Scotland, and is accompanied by a plate. 



2. " On Solfataras and deposits of Sulphur at Kalamaki, near 

 the Isthmus of Corinth," By Prof. D. T. Ansted, M.A., E.B.S., 

 E.G.S. 



After noting the traces of volcanic action east of the Pindus chain, 

 the author described the Solfataras and sulphur-deposits of the neigh- 

 bourhood of Kalamaki as furnishing indications thac there is even 

 now a real though subdued volcanic energy in this part of Europe. 

 At this place, about three miles east of the Isthmus of Corinth, 

 there is a series of cream-coloured and grey gypseous marls, broken
