Dr. W. G. R id ew o o d , F.Z.S., exhibited microscopic sections of the skeletal tube found in the restored tail of one of the oimice (Graphiurus) exhibited by Mr. Thomas. He showed t ia le wall was made up of close-set lamellae, producing in a transverse section a fine concentric striation. Lacunae with numerous branching canaliculi were disposed regularly in relation with the concentric striations, and the general effect was that presented by a transverse section of the humerus or femur of a Frog. Internally to the bony layers and contiguous with the central jelly was a moderately thick layer, which was clear, homogeneous, and highly refractive. Dr. Ridewood also exhibited, by way of contrast, slides of the skeleton of the restored tail of an Iguana Lizard, the skeletal tube in this case being composed of calcified fibro-cartilage and not of bone. In a paper communicated to the Society by Prof. H ickson, F.R.S., and illustrated by lantern-slides, Prof. J. E. D u erd en , of the Rhodes University College, Grahamstown, Cape Colony, gave an account of his observations and experiments on the habits and reactions of Crabs bearing Sea-Anemones in their claws. A communication from Capt. F. W a l l , C.M.Z.S., contained notes on a large collection of Snakes made by Mr. Alan Owston in Japan and the Loo Choo Islands. Mr. H. R. Hocg, F.Z.S., read a paper on a collection of South Australian Spiders of the family Lycosidce contained in the Museum at Adelaide. He stated that this was one of the most widely distributed families of Arachnida, but that, except in size, the many forms varied but very little in general characteristics from the type species found in Italy and Spain. Thirteen species were remarked upon, ten of which were described as new. Mr. Oldfield T homas, F.R.S., read a paper on a collection of Mammals which had been obtained by Col. A. C. Bailward during a shooting-trip through Persia and Armenia during the past summer, and which had now been presented to the National Museum. The specimens had been trapped and prepared by Mr. R. B. Woosnam, who accompanied Col. Bailward. 31 species weie enumerated, and special attention was drawn to the discovery of Calomyscus, a primitive Murine the only ally of which, amongst recent forms, was the N. American Peromyscus. The following novelties were described :__ |
