Field Notes. 



Nuphar lutea var. b. intermedia (Ledeb.)— vide Lond. Cat., 

 9th ed. — This plant, discovered early last century by the late 

 Sir John Trevelyan, of Wallington Hall, Northumberland, still 

 g-rows in the only British station, Chartner's I.oug'h, on the 

 moors to the south of the Simonside Hills, in the county above- 

 mentioned. On the 8th August, accompanied by one of my 

 sons, I visited the spot after a long- walk over moors just 

 becoming- resplendent with the purple of heather, and found the 

 Water Lily more plentiful and luxuriant than on two previous 

 visits made at long- intervals during the past twenty years. 

 And 1 am pleased to think that there seems to be no dang-er of 

 immediate extinction of A\ intermedia. The long- drought has 

 not much diminished the w^ater area in the midst of the peat- 

 filled depression where it is situated, nor do Sphag-num and its 

 allies and the more vigorous growth of Carex ampidlacea, 

 together with a few tufts of Jinicus conglomeratus, appear to 

 encroach upon the lough at a very rapid rate. On the other 

 hand, the plants named seem to shelter the Water Lily, and 

 possibly this is w'hy it appears to have increased recently. 

 Owing- to the treacherous character of the peaty m.argin one 

 had considerable difficulty in procuring- specimens ; but a few^ 

 were obtained, all well fruited, and bearing- the persistent 

 petaloid calyces. —J. Fraser Robixsox, Hull, 19th Aug. 1905. 



Cotyledon Umbilicus (L.) (Navelwort) in Derbyshire. — 



As this curious plant is so rare in Derbyshire, it may be worth 

 while to record that when visiting- Froggatt Edge, Grindleford, 

 with the Rucksack Club, on climbing bent, in December 1903, 

 I saw^ a few young- plants growing at the base of the rocks, not 

 far from the Cave. — W.. H. Pearsox, Manchester, i8th Sep- 

 tember 1905. . 



GEOLGGY. 



Fish Remains in the Lower Chalk, North Lincolnshire. — 



In visiting the well-known quarry near the Humber at South 

 Ferriby recently I obtained the remains of a fish from the 

 quarry men. It had been taken from the marly bands in the 

 uppermost beds of the Lower Chalk underlying the Bclciiiiiitclla 

 plena zone. The specimen is not complete and measures over 

 twelve inches in length and the vertebrae are half an inch in 

 diameter. On submitting the remains to Dr. A. Smith Wood- 

 ward, F. R.S. , that gentleman writes : — 'I have carefully compared 

 them and am of opinion that they represent a new fish allied to 

 Thrissopater of the Gault, and closely similar to my T. magnus
