Micraster cor-anguiniwn-zone, and, as I have stated elsewhere, is 

 identical with the Northfleet, Gravesend, Dartford, Farningham 

 Road, and Foot's Cray Chalk, so that we now know that the topmost 

 beds of this zone mark the whole of this area, the Uintacrinus and 

 Marsupite zones having been denuded. 



While dealing with this subject it may not be inappropriate to give 

 some information respecting the fossils in the British Museum and 

 elsewhere labelled "Bromley" as regards locality. For many years 

 I tried to solve this mystery, not being aware of any outcrop of Chalk 

 in that district. My friend Mr. Watson, of the Catford Natural 

 History Society, has kindly sent me the following: — History of 

 Chisfehurst, by E. A. Webb, p. 838: "From these now disused 

 chalk-pits along the base of Camden Hill large numbers of fossils 

 have been obtained from time to time. The locality, however, 

 has generally been quoted as Bromley. There is a magnificent 

 series of Echinoderms from this parish in the Natural History 

 Museum, South Kensington, several of the examples being 'types '." 



The pits are situated at the back of Willett's Mews ; there is 

 a drawing of them by Mr. Whitaker in his Geology of London, vol. i. 

 The ecclesiastical boundary of Bromley may extend to this pit, hence 

 the confusion which has arisen. The Mews is situated immediately 

 at the bottom of the hill on turning to the left after leaving the 

 ' down side' of Chislehurst Station.

MISCELLANEOUS. 



Geological Survey of India. — Sir Henry Holland, K.C.I.E., F.A.S., 

 came home on furlough from India in the autumn of 1909, leaving his 

 colleague, Mr. T. H. D. La Touche, F.G.S., for the time in charge as 

 acting Director. Both gentlemen having now retired from the Indian 

 Service, Mr. Henry Hubert Hayden, B.A., B.E., F.G.S., has been 

 appointed to succeed to the post of Director of the Geological Survey of 

 India. Mr. Hayden joined the Department on January 3, 1895, and 

 has seen service in most parts of India and Burma. He is, however, 

 best known for his survey of Spiti in the Central Himalayas of the 

 Punjab, and for his work on Eastern Tibet. Since the publication of 

 these two important memoirs he has spent some time in Afghanistan, 

 the results of his work being now practically ready for publication. 



Two Assistants have been recently appointed to complete the Staff 

 of the Indian Survey ; namely, Mr. H. S. Bion, B.Sc, who has been an 

 Assistant to Professor E. J. Garwood at University College, London ; 

 and Mr. C. S. Fox, B.Sc, Lecturer on Mine Surveying in the 

 Birmingham University.
