8 PEOCEEDINGS OF THE 



of L. pallescens appears to be Eastern Central Europe. Messrs. 

 Groves also exhibited specimens of the allied species. 



Dr. Otto Stapf, F.E.S., Sec.L.S., exhibited, for comparison, 

 specimens of L. pallescens from Central Europe. 



Dr. Stapf, Mr. G. C. Druce, and Mr. E. N. Williams engaged in 

 a discussion, and Mr. James Groves replied. 



Mr. G. Claridge Druce, M.A., E.L.S., exhibited as a probable 

 new British plant, Montia lamjjrosjjerona, Chamisso ; the characters 

 by which it is distinguished from M. fontana being, it was stated, 

 the larger, chestnut-brown shining seeds, reticulate rather than 

 tubercular. In M. fontana they are small, dull-black, and strongly 

 tubercular. The plant has a distinctly northern range, and from 

 its being the only form found in the Faeroes, and from its occur- 

 rence in Scandinavia, Russia, and North Germany, it might be 

 expected to grow in Scotland. Mr. Druce has specimens which 

 he found in Ross-shire in 1881 in Glen Spean, and on Loch na 

 Gar, the latter at an altitude of 3400 feet. 



Mr. Clement Eeid believed he had met with the seeds of both 

 species in his researches in British leaf-beds, 



Mr. E. M. Burton, E.L.S., sent for exhibition an oyster-shell 

 with a remarkably large calcareous concretion formed at the point 

 of attachment of the adductor muscle. Prof. Herdman, to whom 

 the shell had been shown, considered the phenomenon due to some 

 parasitic infection which had caused irritation, and consequent 

 growth. There was no trace of any animal having bored in from 

 the outside at the place.
