January 27th, 1874. 

 Professor John Young, M.D., F.G.S., President, in the chair. 



SPECIMENS EXHIBITED. 



Mr John Young, F.G-.S., exhibited a number of drawers con- 

 taining a vakiable series of minerals, chiefly from the Kilpatrick 

 hills and Leadhills, and forming part of the large collection lately 

 presented to the Hunterian Museum by Miss Brown of Lanfine, 

 Ayrshire. Mr Young made some remarks on the specimens, and 

 the districts of country from which they were obtained, and 

 referred to the present scarcity of many of these minerals in the 

 tracts from which they were collected, owing to the veins having 

 been worked out. The magnificent specimens of red Stilbite and 

 Heuhlandite from the Kilpatrick hills were much admired, as 

 were also the very fine series of vanadiates of lead and other ores 

 from Leadhills, among which were examples of that beautiful 

 mineral named Caledonite, a cupreous sulphato carbonate of lead.' 



Mr Robert Gray, F.R.S.E., exhibited a series of birds from 

 Australia and New Zealand, including Ayteryx owenii, of which 

 three specimens were on the table, Strigops hahroptilus, and Tricho- 

 glossus versicolor, the latter being a rare species, from the northern 

 territory. Mr Gray expressed himself indebted for these speci- 

 mens to Dr Godfrey Howitt of Melbourne, and Mr Robert 

 Anderson of Cape Schanck. 



Mr Peter Cameron, jun., exhibited specimens of Cynipidae and 

 Tenthredinidae, including the following species: Andricus nodidi, 

 bred from swollen oak twigs found at Kenmuir; A. amenti, bred 

 from small brown galls on male catkins of the oak; A. ramuli, the 

 maker of the cotton-gall of the oak ; Croesus varus, from Rannocli ; 

 Eriocampa adumbrata, bred from slimy larvae found feeding on 

 the hawthorn ; and Taxonus coxalis, from Rannoch, recorded 

 lately for the first time as British. 



Dr Young called the attention of the Society to the young 

 King-Crab {Limuhis polyphemus), which was still living and 

 seemin<^dy healthy. He also described two new star-pored polyzoa 

 from the Carboniferous limestone shales. Mr John Young had 

 observed the peculiarities which distinguish these specimens in the 

 course of last summer, and he and Dr Young were preparing for
