March 1, 1881. 

 Professor Flower, LL.D., F.R.S., President, in the Chair. 



The Secretary exhibited a dead specimen of a large Spider of the 

 genus Mygale, which had been presented to the Society's collection 

 alive by Dr. A. Stradhng, C.M.Z.S., on March 17, 1880, being the 

 example referred to by Dr. Stradling in a letter published in ' Land 

 and Water ' in June 1880 (vol. xxix. p. 510), as also the shed integu- 

 ment of the same Spider. Mr. Butler, having kindly examined the 

 specimen, had referred it, with some doubt, to Mygale bisfriata, 

 Koch. It had been obtained by Dr. Stradling at Bahia. 



In the Gardens the Spider had been kept in a case kept heated 

 with hot water to a temperature of about 75 degrees Fahr., and fed 

 with cockroaches, upon which it appeared to have thriven well ^. 

 On the 27th August the Spider shed its skin, which process (as 

 witnessed by the Superintendent and Mr. Thomson in a smaller 

 example, probably of the same species) lasted about four hours '. 



The following papers were read : — 



^ See Mr. Thomson's letter, 'Land and Water,' vol. xxix. p. 551. 

 ^ See Mr. Bartlett's description of the process, in ' Land and Water,' Feb 5, 

 1881 (vol. xxxi. p. 102).
