Mytilus ? (Brackish water. ) 



From J. G. Heatley. Esq., I have the pleasure to acknowledge the presentation of 



a large and interesting collection of Shells, chiefly marine, procured from both the 



Asiatic and Australian shores of the Indian Ocean. The number of species comprised 



in this collection is far too great for me to attempt a catalogue of them on the present 



occasion. 



Insecta. 



A valuable box of Insects, collected in Afghanistan, and especially interesting from 

 the attention which has been alike bestowed on all the orders, has been presented to 

 the Society by Dr. Thomson. The general character of these, I may briefly remark, 

 and as may be supposed, is European, with an admixture of tropical forms, analogous 

 to those found on the Himalaya. A variety of British species occur, and among the 

 very few Lepidoptera sent, are included the extensively distributed Cynthia cardui, 

 little Polyommatus Alexis verus, which the Society also possess from Kumaon, 

 Hipparchia Megcera, of which also we have a Kumaon example, other species of 

 this group— one common in the vicinity of Calcutta, and a handsome white-bordered 

 species allied to H. Semele, — a Thecla, which appears to be the European Bcetica 

 figured by Boisduval, Thestia Pirene, Sphinx convolvulus, the domestic Bombyx mori, 

 and five or six other species undetermined. The number of Hymenoptera, Coleoptera, 

 Orthoptera, and even Diptera, as well as Hemiptera, is considerable ; but I cannot at 

 present do more than notice them thus generally and briefly. 



Again congratulating the Society upon the extraotdinary number of donations with 

 which it has been lately favored, indicative of the rapidly increasing interest taken in 

 its Museum, and which, it may readily be conceived, has found me pretty ample 

 employment in determining so many species as have been enumerated, not to mention 

 various others, it now only remains to subscribe myself, 



Sir, 



Your most obedient Servant, 



Edward Blyth.
