side of the valley in a series of curves, with steep rocky banks 

 on the convex, and low-lying lush meadows on the concave 

 sides of the bends. 



On arriving at Balby the Permian formation was left and the 

 Trias was reached, a quarry on the roadside showing a section 

 ■of Bunter Sandstone with current-bedded post-glacial gravels 

 above. 



The party led by Mr. M. H. Stiles were joined by some of 

 the mycologists, namely, Messrs. T. Birks, W. N. Cheeseman, 

 and Thos. Gibbs, who had been taking part in the fungus foray 

 at Cadeby. As will be seen by the report sent in, several speci- 

 mens were found that had not rewarded the fungus-men during 

 their week's work until this bit of new country was explored. 



On arrival at Doncaster the members assembled for tea 

 at the Glyn Hotel, after which the Sectional and General 

 Meetings were held under the chairmanship of the Rev. W. 

 Fowler, of Liversedge, President of the Union. The various 

 sections handed in their reports of the day's finds, and votes 

 of thanks were given to the local guides and to the landowners 

 and quarry proprietors for permission to visit their estates. 



The . following is a record of the objects observed in the 

 locality during the excursion, and in the case of the Bryological 

 report a general moss list for the district is added. 



Of course the time of the year at which the excursion was 

 held, made the records in some sections very meagre, but still 

 the appended lists from the different recorders will show that 

 the day was far from unprofitable. 



Mr. John W. Taylor, F.L.S., President of the Conchological 

 Section, reported that he and Mr. W. Denison Roebuck, F.L.S., 

 had spent their day in the investigation of the ponds at Cusworth 

 in search of a peculiar form of Limncea auricularia which had 

 been sent from that locality some years ago. 



In this object they were not successful, for although a few 

 examples of the species were found they were young and of the 

 ordinary form. One or two Linuicea truncatula occurred, a few 

 Planorbis nautileus, numerous PI. albus, and a few very young 

 PL carinatus, along with a characteristic example of var. dtscu 

 Jbrmis. Bythinia tentaculata was common, and several examples 

 of Valvata cristata occurred. The Bivalves found included a few 

 examples each of young Splicer ium corneum, Pisidium pusillum, P. 

 obtusale, and P. fontinale. One or two Caddis-cases found were 

 built mainly of Planorbis albus, Pisidium pusillum, and young 

 Bythinia tentaculata. A single example of Succinea elegans was
