The majority of the members present showed a kindly 

 interest in mycology by carefully collecting- all the specimens 

 they met with. 



On the Heather on AUerthorpe Common were numbers of 

 a large spider, respecting which the Rev. O. Pickard-Cambridge 

 writes : — Its name is Epeira quadrata Clk., a young and very 

 small specimen. When full grown it is one of our largest, 

 handsomest spiders. It is local but generally abundant where 

 found. 



For the bryologists Mr. J. J. Marshall writes : — Owing to 

 a series of adverse circumstances the meeting was not a success 

 from a bryological point of view. The dry season, the arid 

 character of the country traversed, and the disastrous fire on 

 AUerthorpe Common combined to reduce the specimens gathered 

 to very small proportions. Nineteen mosses and five hepatics 

 were observed. Four mosses are worth recording- : — Dicraimm 

 spuriiun, from the common, an old station ; Hypnum chrysophyl- 

 lum, Cylindrothecium concinnum, and Barbuta Horiischuchiana 

 were found on a bare patch of ground on the chalk near Mill- 

 ington.
