The fragineut consists of the proximal third of a left fore-wing. 

 It is remarkable for its size, being 64 mm. long and 40 mm. broad, 

 the complete wing having an estimated length of 190 mm., or 

 7*5 inches ; the whole insect (with wings exten-ded) must have had 

 a span of over 400 mm., or 16 inches. 



The anterior wing-margin is strongly tuberculated proximally, and 

 more distally bears a closely- set series of pointed spines dii-ected 

 outwards towards the wing-apex. The hinder wing-margin is also 

 spinous, the spines being a little way inwards from the edge, and 

 possibly serving to interlock the fore and hind wings during flight. 

 The radial and median veins are missing, but the characters of the 

 costa and subcosta on the anterior portion of the wing, and of the 

 cubital and anal veins on the hinder part, show clearly the close 

 relationship of the insect to the members of the family Meganeuridae, 

 a group including the enormous Meganeura monyi, Brongniart, from 

 the Stephanian of Commentry (Allier). The wing is referred to the 

 genus Meganeura as a new species. The precise horizon from which 

 the shale was derived cannot be determined, as the Tyning waste-heap 

 has received material from five different collieries. 



Annual Gknekal Meeting. 



2. February 20, 1914.— Dr. Aubrey Strahan, F.R.S., President, 

 in the Chair. 



The Reports of the Council and of the Library Committee were 

 read. It was stated that of the 65 Fellows elected in 1913 (2 more 

 than in 1912), 48 paid their admission fees before the end of that 

 year, making, with 16 previously elected Fellows, a total accession of 

 64 in the course of 1913. During the same period the losses by 

 death, resignation, and removal amounted to 43 (9 less than in 1912), 

 the actual increase in the number of Fellows being, therefore, 21 (as 

 compared with an increase of 5 in 1912). The total number of 

 Fellows on December 31, 1913, was 1,308. 



The Balance-sheet for that vear showed receipts to the amount 

 of £3,367 8s. Ud. (excluding the balance of £641 2«. Zd. brought 

 forward from 1912), and an expenditure of £3,137 12s. \d. 



The Reports having been received, the President presented the 

 Wollaston Medal to Dr. John Edward Marr, F.R.S. , addressing him 

 as follows : — 



Dr. Mark, — I am pleased that it has fallen to my lot to address, on such an 

 occasion as this, one with whom I have so long enjoyed an intimate friendship, 

 and by whose work I have profited so greatly. 



At the conclusion of a distinguished University career you commenced, in 

 1878, a series of investigations, through which your name will always be 

 associated with the Lower Palseozoic rocks. Concentrating your attention first 

 on the zoning of the strata between the Coniston Limestone and the Coniston 

 Grits in the Lake District, you continued the work of Hughes, Aveline, and 

 Salter, established a classification, and discussed the division between the 

 Silurian and those Cambrian subdivisions of Sedgwick which are now known 

 as Ordovician. In 1880 you carried your researches into North Wales, and 

 instituted a comparison of the sequence as there developed with that of the 

 Lake District. During the same year you laid before this Society the results
