SPECIMENS EXHIBITED. 



Mr Peter Cameron, jun., exhibited an interesting collection of 

 insects, chiefly from the neighbourhood of Glasgow, and including 

 the following : — Sawflies — Pachyprotasis variegata, Lophyrus virens, 

 L. pallipes, Taxonus glottianus, Cam., a new species found in 

 Kenmuir woods ; and Tenthredo obsoleta, a species not hitherto 

 recorded as British. Bees — Bomhus fragrans, together with its 

 nest, found in Possil marsh ; and Nomada xanthostica, a very rare 

 species, which had been taken on the Tollcross sand-hills. 

 Cynipidae — Cynips Ugnicolci, C. radicis, Trigonaspis megaptera, and 

 SpatJiogasfer haccarum, along with their galls. Beetles — Donacia 

 crassipes, found on the water-lilies at Bardowie Loch ; Dyschirius 

 impundipennis, found on the sands at Troon ; and Bembidium 

 paludosum, from Possil. Mr Cameron likewise exhibited a curious 

 neuropterous insect, Bajjhidia maculicolUs, and a grasshopper, Tetrix 

 lipiimctata, both taken in the West of Scotland. 



Mr John Kirsop exhibited a small collection of birds from 

 Berbice, and Mr James Watson laid on the table a singularly- 

 formed bird's nest from Jamaica. 



Mr Robert Gray, F.R.S.E., exhibited a very perfect specimen of 

 the Ivory Gull (Larus ehurneus), which was shot at Campbelton on 

 the 21st January last. The bird was remarkable for the purity of 

 its plumage, being wholly of a spotless white. Mr Gray remarked 

 that it agreed precisely with the published description of the 

 variety known among ornithologists as the Short-legged Ivory 

 Gull {Pagopliila hr achy tarsus, Holboll), a variety which the late 

 Prince Bonaparte had shown to be identical with the Larus neveus 

 of Brehm. Compared with the ordinary form, it is whiter and 

 more handsome, being larger and having the bill shorter, with the 

 tip orange-coloured. This variety had previously occurred once 

 in Scotland, a specimen, now in the collection of Sir William 

 Jardine, having been obtained in the county of Caithness some 

 years ago.
