{^Microscopical and Natural History Section^ 

 ■ Annual Meeting, April loth, 1893. 



The President of the Section, Mr. R. E. CUNLIFFE, 

 in the Chair. 



Mr. Rogers exhibited about 30 species of AcliatinellcE 

 recently collected in Oahu — one of the Hawaiian Islands. 

 The species for the most part were representatives of the 

 group or sub-division, AcJiatinellastriun. He called attention 

 to the similarity of these so-called species to one another, 

 differing principally in colouration and band formulae. 



Mr. Rogers further remarked that the Achatinella; were 

 confined in their geographical distribution to the Hawaiian 

 Islands ; each island has some species peculiar to itself, and 

 each particular ravine has its own particular species ; but 

 intermediate forms are found in intermediate spaces. 

 Another peculiarity of a large number of the species is that 

 the spires of the shells are as often found sinistral as dextral. 



Mr. G. H. Broadbent, M.R.C.S., exhibited drainage 

 water from a manure-heap at Ashton, containing infusoria, 

 under the microscope, and gave the results of his observa- 

 tions extending over the last twelve months.
