284 THE EOCENE FLORA AND FAUNA. In summarising the chief points in this report I wish to emphasise the following :— 1. That wherever a district near London has been examined, it has been found to be infected, but in no case have the trees suffered so much as at Lord's Bushes. 2. That the disease has shown itself to be much more destructive during this autumn than at any time last year. 3. That Melanconis stilbostoma does occur on living branches and causes their death, but like Valsa oxystoma, it, as a rule, reaches its perfection on dead branches only. 4. That the course of the disease is very rapid. I wish to thank Mr. W. Cole, the Hon. Sec. of the Club, for the help he afforded me last autumn, and also Mr. McKenzie, the Forest Superintendent, who so readily gave permission to remove a large dead tree, when he heard of the investigation it was proposed to make. My thanks are also due to Mr. G. E. Shaw and to Mr. J. H. Pledge for the photographs that illustrate this report. THE EOCENE FLORA AND FAUNA OF WALTON-NAZE, ESSEX. By J. P. JOHNSON. [Read November 24th, 1900.] In 1887 the Geological Survey published Mr. W. Whitaker's memoir on The Geology of the Eastern End of Essex. The only Eocene fossils listed in it are some Chelonians and a Mammal from the London Clay of Harwich. Not a single species is noted from Walton-Naze, and I do not know of any subsequent record. Many years have passed since I last visited this classical locality, and some of the fossils mentioned below are no longer in my collection, but I remember the specimens and the finding of them so well that I have no hesitation in listing them. They were found on the foreshore between Walton-Naze and Frinton, among the patches of iron-pyrites left behind by the retreating tide, and were evidently washed out of the London Clay cliffs. Those of the specimens that I have been able to find I have handed over to the Essex Field Club's Museum at Stratford, They are indicated by an asterisk.
