A Gynandromorphic Specimen of the Earwig (Forficula 



auricularia). 



Prof. J. P. Hill, F.R.S., F.Z.S., remarked as follows:— 

 The specimen (a photograph of which was exhibited) attracted 

 attention by reason of the asymmetry of its forceps. The right 

 limb of the latter measured 3*25 mm. in length, and is unmistake- 

 ably of the male type, being stout and distinctly curved. The 

 left limb measured 2*75 mm., and is just as unmistakeably of the 

 female type, being slender and only slightly curved. 



Dissection of the specimen revealed the presence of a well- 

 developed testes, containing fully formed sperms, on the right 

 side. The left gonad was not observed and was probably either 

 absent or very rudimentary. It is certain that a well-developed 

 ovary was not present on this side. 



Dr. A. Smith Woodward, F.R.S., Vice-President, exhibited 

 enlarged models, made by Mr. Frank 0. Barlow, of the first 

 lower molar tooth of a large Chimpanzee, Melanesian Man, and 

 Piltdown Man {Eoanthropus dawsoni). He maintained that the 

 latter tooth was of the megadont human type. 



Mr. D. M. S. Watson, F.Z.S., exhibited and explained by 

 diagrams, models of the teeth of fossil horses. 



Professor H. Maxwell Lefroy, M.A., F.Z.S., described the 

 Silkworms and Silk industry of India, illustrating his account 

 with lantern-slides and specimens of the Silk Moths, Cocoons, 

 and Silk.
