was a well-known species, common on chalky soils, and he had seen it in 

 Kent, Sussex, Surrey, Wiltshire, and on the limestone in Derbyshire, &c. 

 It evidently prefers, and most likely requires, challv or lime for its opera- 

 tions. He suggested that search should be made at Purfleet or Grays, 

 on the chalk, for the mollusc. 



The President said it was clear from Mr. Dalton's and Mr. Christy's 

 observations that Cyclostvma had once lived in Essex, possibly finding 

 suitable conditions in the chalky boulder-clay ; and he suggested the 

 possibihty that the disappearance of the species was due to the removal 

 of the chalky clay by superficial denudation and other causes. 



Mr. H. J. Barnes exliibited some shells of a species of Ostraa found in 

 large quantities in digging a new sewer at Leyton at a distance of about 

 twenty feet from the surface. 



Mr. H. Corder exliibited, and read some notes on, tln-ee Neohthic 

 Implements from the neighbourhood of Chehnsford [Trans, ii. 29.] He 

 also exhibited and explained some ancient Bronze Implements ("Socketed 

 Celts "), found two years ago in a field near Little Baddow, Essex [Trans. 

 ii. 31] , and some bones of Pleistocene Mammalia from the brick-earth, 

 Chelmsford. 



Mr. James English read a paper entitled " The First Night's ' Sugaring ' 

 in England : a reminiscence of Epping Forest in 1843 " [Trans, ii. 32.] 



Mr. Meldola said he was sure Lepidopterists would read with pleasure 

 Mr. English's chatty account of the earliest application of a process to 

 which they owe a revolution in the extent and beauty of theu' collections. 

 One interesting fact appeared to be clearly established by the use of the 

 method of " sugaring," and that was the possession of an organ of 

 smell by Lepidoptera and other insects. He suggested that it would be 

 an important experiment to remove the antenna of moths, and see if 

 they found then- way to " sugar" when thus mutilated. In the course of 

 conversation Mr. EngUsh expressed his beUef that moths would not come 

 freely to sugar when the trees were infected with honey-dew, and that the 

 circumstance explains one at least of the causes of the uncertainty of 

 sugaring as a mode of collecting. 



A unanimous vote of thanks was passed to the authors for their 

 papers. 



At the Conversazione Mr. J. S. Morten exhibited, under the microscoj)e, 

 some specimens of parasites belonging to the genera Avfja.^, Trichodectes, 

 and Hcematopinuii ; Mr. -J. D. Cooper two Flint Spear-heads and a Knife 

 from the Ancient Indian Burial Mounds near BeHze, Central America ; 

 and Mr. W. Cole a series of Noctuce for the purpose of illustrating 

 Mr. English's paper.
