phoq)]iorea, regarding which Mr Gray remarked that they were of 

 extreme size when compared with specimens taken off tlie Dunbar 

 coast, and were besides much lighter in colour. Examples of 

 this zoophyte from the east of Scotland were, as a rule, much 

 smaller, and of a deeper red, than those of the west coast, and it 

 might be of importance to ascertain if they were not two species. 

 He had examined in one day as many as seven or eight hundred 

 of the smaller kind, brought on shore by tlie Dunbar fishermen. 



Mr John Young exhibited a specimen of Calamites nodoms from 

 the Spiinghill pits, Baillieston, showing the nodes to which the 

 lateral fronds were attached; also a fine lateral frond of the same 

 plant from Craigneuk pit, near Motherwell, j^resented to the 

 Hunterian Museum by Mr David Wingate. Mr Young remarked 

 that this wtis the first frond of this plant which he had yet seen 

 from the Scottish coalfield. He pointed out its relation to the 

 ■stem, and wherein it differed from other sjiecies of the genus 

 Calamites. 



Mr Young also exhibited a mounted series of small fossil 

 organisms, which he had obtained from a travelled boulder of 

 limestone embedded in the boulder clay at Gilmorehill. This 

 limestone, he stated, agreed in mineral composition, and in the 

 character of its fossils, with the bed of limestone which underlies 

 the coal of the Campsie district, locally known as the "white 

 limestone." The outer surface of the boulder had become partially 

 rotted from lying so long in the till, and so abundant were the 

 organisms in the stone, that from a small quantity of the rotted 

 material, scraped from the face of the boulder, he had obtained 

 several thousand specimens of Entomostraca, and a small spii'al 

 annelide, all in a good state of preservation. The Entomos- 

 traca were all of species that had recently been determined by 

 Professor Rupert Jones and Mr J. W. Kirby as new to science, 

 and were named as follows: — Cythere fahnlina, a large variety, C. 

 pungens, C. secans, and C. siibula. The annelide, Spirorhis carhon- 

 arius, is a well known species, but seldom found in such good 

 preservation as in the present instance. Mr Young stated that 

 the foregoing organisms, along with one or two other species of 

 Ci/fhere, chai'acterise, in a measure, all the so-called fresh water or 

 estuarine strata of the Lanarkshire coalfield, several of the species 

 being found to range from the Ijottom to the top of the system; 

 and although the beds in wliich they occur often alternate with
