Mr. Newman exhibited a melanic Opovabia dilutata taken 

 wild at Bexley Woods, October 23rd, 1907. This is a 

 melanic form new to Kent, and possibly the darkest melanic 

 form of this species yet taken in England. (?) 



Mr. Grosvenor exhibited a long series of Lycczna (Polyom- 

 matus) icams from the N. Downs, and a few from Aberdeen, 

 including a large percentage of blue females. One male had 

 a white edging in the border, in place of the black margin, 

 several with a tendency to ab. persica, and ab. icarinus, and 

 specimens with crescents on both fore- and hind-wings. 

 Among the females one from Aberdeen had large white 

 wedges on all the wings, two from the N. Downs had 

 confluent spots on the under-surface, and a few had the 

 spots enlarged in area. 



Mr. W. J. Lucas exhibited some species of land and 

 fresh-water shells of the New Forest, and read the 

 following note : " Generally speaking the New Forest is 

 not considered a good locality for these animals. I was 

 therefore somewhat surprised to find that by very casual 

 collecting I had obtained 29 species. No doubt this total 

 could be doubled at least. The species exhibited are : — 

 Hyalinia alliaria, H. nitidula, H. fulva, H. nitida ; Helix 

 rotundata, H. cantiana, H. fuse a, H. caperata ; Pupa cylindracea 

 (umbilicata) ; Vertigo pygmcea ; Balea perversa; Cochlicopa 

 lubrica ; Succinea putris, S. elegaus ; Planorbis albus, P. 

 spirorbis, P. complanatus ; Limnaa pcregra, L. stagnalis, L. 

 pal ust ris, L. glabra ; Bytliinia teutaculata ; Valvata piscinalis ; 

 Anodonta cygnea, var. anatina ; Sphccrcum corneum ; Pisidium 

 amnicum, P. fontinale, P. pusillum, P. nitidum. These have 

 all been secured actually in the Forest ; the fields and 

 hedgerows around have not been examined.''

 belonging to the Myxogasters, found near the Black Pond, 

 Esher Common, November 17th. 



Also the following varieties of dragonflies, all from the
