removing the antennae of moths, and seeing whether they found their way 

 to sugar when thus mutilated. The object of this experiment was to test 

 the function of the antenna3 as organs of smell. Since the last meeting 

 he had met with a paper recently published by G. Hauser (Zeit. fiir wiss. 

 Zool., vol. xxxiv., 1880, pp. 367—408), in which such experiments had 

 actually been conducted, and which went to support the views advocated. 

 In all the Orthoptera, Pseudo-Neuroptera, Diptera, Hymenoptera, and in 

 many Lepidoptera, Neuroptera, and Coleoptera, a strong nerve had been 

 discovered arising from the cerebral ganglion and passing into the 

 antenna3. A terminal sensory organ with which the nerve-fibres are 

 connected, and accessory organs formed by the pits or cones filled with 

 fluid are described. The author gives detailed descriptions and figures of 

 these organs in the orthopteron, Calopterus Italicus. The function was 

 investigated by cutting ofi' the antenna of insects which had previously 

 been tested by turpentine, carbolic acid, &c. Insects thus mutilated 

 exhibited no repugnance to these odours, nor did they rush to food. 



The Secretary read an extract from a letter received from Mr. K. M. 

 Christy respecting the occurrence of Cydoatonia elegans in Essex [Pro- 

 ceedings, II., xi] . Mr. Christy had found the shells in considerable 

 abundance in a deposit of alluvium at Chignal St. James, near Chelms- 

 ford. Last year, and again this spring, he found several dead shells a 

 few inches below the surface in a railway-cutting close to Saffron Walden, 

 but has not found any living specimens yet. The occasion on which he 

 made his nearest approach to finding it living was one day at the end of 

 last August, when he happened upon plenty of the animals in a wood 

 called the "Eivy Wood," just on the other side of Linton, and also in 

 abundance beside the road right into the town. Now as Linton is built 

 on the very boundary between Cambridgeshire and Essex, he might fairly 

 say that he had found living Cyclostoma elegans only a few hundred yards 

 outside our own county, and before the summer closed Mr. Christy was 

 hopeful of being enabled to report the occurrence of the animal in Essex. 

 Another shell he very much desired to find in Essex was Helix puinatia. 



Mr. Meldola exhibited the larva of a species of Them (either T.Jirmata 

 or T. oheliscata) the body of which was neatly and tightly packed with 

 cocoons of some species of ichneumon-fly. The flies had hatched out, 

 and he hoped at a future meeting to give the name of the species. 



Mr. Harting presented to the Club a copy of his paper in the ' Popular 

 Science Review,' on the occurrence of the Roe Deer in England, and, in 

 doing so, he hoped the members would do all in their power to investigate 

 the characters and history of the Deer now existing in Epping Forest. 

 He pointed out that there were great differences between the horns of the 

 Epping specimens and the normal horns of the ordinary Fallow Deer ; 

 and it would be of interest to endeavour to explain this modification, and 

 to ascertain whether these animals were the descendants of Deer imported 

 into the Forest, or whether they formed the remnant of the ancient breed 

 of Deer surviving from remote times.
