514 OSTRACODA OF CARBONITEROTJS POEMATIONS OY BRITISH ISLES. 



Note.— A few weeks ago Mr. J. Ward, F.G.S., of Longton, 

 favoured us with a specimen of impure limestone from the Mill- 

 stone Grit of Danebridge, Macclesfield, containing Ostracoda. Unfor- 

 tunately the matrix is so refractory and the valves are so imperfectly 

 preserved that we cannot in any case determine either the genus or 

 species. Mr. J. Bennie informs us also that he has incidentally 

 noticed Ostracods, in beds holding a Millstone-Grit position, in 

 Scotland. So it is evident that fossils of this order exist in rocks of 

 this Middle Carboniferous age, and that only additional search is 

 required to bring them to Hght. — October 18, 1886.

Dr. Woodward congratulated the Authors on their care and 

 patience in working up the subject. Much of this work was done 

 under considerable discouragement, since the siliceous examples in 

 which the structure of the appendages is preserved are not available 

 in this country, and without these authors are dependent solely on 

 the examination of the characters presented by the carapaces. 

 Mr. Brady, who had examined the specimens upon which Prof. 

 Bupert Jones's observations were founded, was satisfied that the 

 classification adopted by the author for the fossil Ostracoda was the 

 best that the materials afforded.
