Mr. E. T. Newton, E.E.S., exhibited some specimens o£ his Mus 

 ahbotti and made the following 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 reseuibling those of Mus sijlvaticus, but 

 wanting the characteristic front tubercle of the anterior lower 

 cheek-tooth. This fossil form was named 31. ahbotti, after Mr. Lewis 

 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 ahbotti for a mouse from 

 Trebizond (Proc. Zool. Soc. 1880, p. 61). I regret my oversight, 

 and avail m3^self of the opportunity, so courteously afforded me, of 

 rectifying the error. It is proposed to name the fossil mouse 

 Mus leivisi, so that it may still be associated with its energetic 

 discoverer." 



A communication was read from Dr. Gr. Stewardson Brady, 

 C.M.Z.S., containing an account of the Copepoda collected, 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 shown that several species were identical with 

 vi-ell-kuown European forms, and others closely allied, but that many 

 were entirely distinct and presented very interesting peculiarities.
