Show 1899.J ON THE OSTEOLOGY OF THE TUBINARES. 381 March 21, 1899. W . T. BLANFORD, Esq., LL.D., F.E.S., Vice-President, in the Chair. Mr. E. T. NeAvton, F.K.S., exhibited some specimens of his Mus abbotti and made the folloAving remarks:-"Among the fossil remains of small rodents found in the ossiferous fissure at Ightham, Kent, and described in 1894 (Quart, Journ. Geol. Soc. vol. 50. p. 188), were a few rami of mice resembling those of Mus sylvaticus, but wanting the characteristic front tubercle of the anterior lower cheek-tooth. This fossil form was named M. abbotti, after Mr. LeAvis Abbott, whose zeal in working out the fissure had brought to light these and many other interesting fossil remains. Mr. Barrett- Hamilton has called my attention to the fact that Mr. Waterhouse had previously used the name of Mus ctbbotti for a mouse from Trebizond (Proc. Zool. Soc 1880, p. 61). I regret my oversight, and avail myself of the opportunity, so courteously afforded me, of rectifying the error. It is proposed to name the fossil mouse Mus lewisi, so that it may still be associated with its energetic discoverer." A communication was read from Dr. G. Stewardson Brady, C.M.Z.S., containing an account of the Copepoda collested, chiefly by means of the surface-net, by Mr. G. M. Thomson, of Dunedin, and by Mr. H. Suter, on behalf of the Zoological Museum of Copenhagen. It was shoAvn that several species were identical with well-known European forms, and others closely allied, but that many Avere entirely distinct and presented very interesting peculiarities.
