Mr. Thomas Scott, F.L.S., Corresponding Member, exhibited 

 specimens of Rhincalanus gigas, Brady, and Ectinosonia atkinti- 

 cum, B. and R., two copepods from the East of Scotland, upon 

 which he made some remarks.* 



Mr. Andrew Scott exhibited specimens of Cecrops latreillei. 

 Leach, and Lcemargus muricatus, Kroyer, two pai-asitic species 

 of Crustacea found on a short sunfish {Orthagoriscus moke) from 

 the Firth of Forth.t 



Mr. A. Soinerville, B.Sc, F.L.S., Vice-President, showed 

 specimens of Bklens cernua, L., gathered near Ballina, County 

 Mayo. 



Professor Thomas King showed specimens of Vaccinitim, 

 intermedhon, Ruthe, from Cannock Chase, Staffordshire, where 

 the plant was discovered by Professor T. G. Bonney, F.R.S., 

 in 1SS6. It is plentiful in certain spots where Vacciniuni 

 Myrtillus, L., and V. Vitis-Idcea, L., grow abundantly, and is 

 believed to be a hybrid between these two species. A paper on 

 the occurrence of V. intermedium in Britain was I'ead by Mr. 

 N. E. Brown, A.L.S., at a meeting of the Linnean Societj' on 

 5th May, 1887.

Mr. Robert Broom, M.B., CM., B.Sc, exhibited a series of 

 specimens illustrating the modifications of the quadrate bone 

 in the various groups of vertebrates. In the course of his 

 remarks he traced the various changes in the arrangement for 

 articulating the lower jaw, from the condition in the Shark, 

 through the higher Fishes, to the Amphibians. He pointed out 

 that from the Amphibians there had been two lines of descent, 

 viz. : (first) that of the Reptiles and Birds, in which the quadrate 

 bone had increased in size and strength ; and (second) that of 

 the Mammals, in which the quadrate had degenerated into a 

 cartilaginous plate — the interarticular fibro-cartilage. 



Mr. James J. F. X. King, F.E.S., showed some uncommon 

 varieties of Boarmia repandata, L., and Camptogramma 

 hilincata, L., taken by him last summer in the Loch Maree
