SCIENTIFIC SOCIETIES. 35 



Tortoises of Aldabra. Along with these Tortoises were found numerous 

 bones of the extinct Lizard, Didosaurus mauritianus, of which an account 

 is also given. 



Mr. F. E. Beddard gave descriptions of some new species of Earth- 

 worms from various localities, belonging to the genera Octochcetus, Acantho- 

 drilus, Benhamia, Microdrilus, Perionyx, Moniligaster, Notykus, Tricochceta, 

 and llyogenia. Of these nine genera Octochatus, Microdrilus, and Ilyogenia 

 were characterised as new to science. 



Mr. R. H. Burne read a note on the presence in the Common Hag, 

 Myxine glutinosa, of a branchial basket, which had not been previously 

 recognised in this fish, though already described in the larger Hag, M. 

 bdellostoma. — P. L. Sclater, Secretary. 



Entomological Society of London. 



December 7, 1892. — Frederick DuCane Godman, Esq., F.R.S., 

 President, in the chair. 



The President announced the death, on the 2nd December, of Mr. 

 Henry T. Stainton, F.R.S., an ex-President of the Society. A vote of 

 condolence with Mrs. Stainton was passed by the meeting. 



Mr. Frank Bouskell, of 11, Lansdowne Road, Stoneygate, Leicester; 

 Mr. George C. Dennis, of Tower Street, York ; Mr. Charles B. Headley, 

 of Stoneygate Road, Leicester ; Mr. William Mansbridge, of Luther Place, 

 Horsforth, near Leeds; and the Rev. George W. Taylor, of St. Barnabas, 

 Victoria, British Columbia, were elected Fellows of the Society. 



Mr. Jenner Weir exhibited a species of Acrsea from Sierra Leone, which 

 Mr. Roland Trimen, who had examined the specimen, considered to be a 

 remarkable variety of Telchinia encedon, Linn. It was a very close mimic 

 of Limnas alcippus, the usual Western African form of Limnas chrysippns. 

 The upper wings of the specimen were rufous and the lower white, as in 

 the model, and the resemblance in other respects was heightened by the 

 almost total suppression of the black spots in the disc of the upper wings, 

 characteristic of the usual markings of T. encedon. 



Mr. F. J. Hanbury exhibited a remarkable variety of Lyccena adonis, 

 caught in Kent this year, with only one large spot on the under side of 

 each upper wing, and the spots on the lower wings entirely replaced by 

 suffused white patches. He also exhibited two specimens of Noctua 

 xanthographa of a remarkably pale brownish grey colour, approaching a 

 dirty white, obtained in Essex in 1$91 ; and a variety of Acronycta rumicis, 

 also taken in Essex, with a beautiful dark hind margin to the fore wings. 



Mr. H. J. Elwes exhibited a living specimen of a species of Conocephalus, 

 a genus of Locustidce, several species of which, Mr. C. O. Waterhouse and 

 Mr. McLachlan stated, had been found alive in hothouses in this country.
