On further search two other specimens exhibiting the same 
structure had been found, and it appeared therefore that Dormice, 
like Lizards, were able partly to regenerate their tails, when 
these important balancing-organs got accidentally broken. 
Dr. W. G. Ripewoop, F.Z.8., exhibited microscopic sections of 
the skeletal tube found in the restored tail of one of the Dormice 
(Graphiurus) exhibited by Mr. Thomas. He showed that the 
wall was made up of close-set lamellee, producing in a transverse 
section a fine concentric striation. Lacune 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. Hicxson, 
F.R.S., and illustrated by lantern-slides, Prof. J. HE. DurrpDmEN, 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, Watt, O.M.ZS., contained 
notes on a large collection of Snakes made by Mr, Alan Owston 
in Japan and the Loo Choo Islands. 
Mr. H. R. Hoce, F.Z.8., read a paper on a collection of South 
Australian Spiders of the family Lycoside 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 'THomAs, 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. Wocsnam, who accompanied Col, Bailward. 
31 species were 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 :—
