[Microscopical and Natural History Section.'] 



Ordinary Meeting, December 18th, 1893. 



Mr. R. E. Cunliffe, President of the Section, in the Chair. 



Mr. J. F. Allen and Mr. J. Watson were elected 

 Associates of the Section. 



The President moved : — " That the Section notes 

 with great regret the loss to science caused by the death of 

 John Tyndall, LL.D., M.D., D.C.L., Ph.D., F.R.S., F.C.S." 



Dr. Broadbent gave a microscopical demonstration of 

 Infusoria found in water obtained from manure heaps. 



Mr. J. C. Melvill, F.L.S., exhibited a specimen of 

 Bulimus (Porphyrobaphe) labeo (Broderip) from Peru, a 

 very scarce land mollusk, conspicuous for the swollen, 

 almost diseased appearance of the marvellously incrassate 

 and reflected outer lip, which has deep pittings and crenula- 

 tions all over its swollen and tumid surface, not dissimilar 

 to the appearance of cooled lava. 



Mr. Melvill also exhibited eleven of the thirteen or 

 fourteen known Rhopalocera of New Zealand, which 

 country is the poorest in the world for its size for not only 

 these insects, but also those of most other orders, although 

 the bulk of the Coleoptera and Hymenoptera which do 

 occur are peculiar, and show the extreme antiquity of this 

 land, formerly, according to Wallace, a large continent 

 embracing the Macquaries, Lord Howe Island, The Auckland 

 and Campbell Isles, and Norfolk Island. That it has been 

 dissociated from Australia from the earliest times, is evident 

 by the differences in the Flora as well as in the Fauna.
