HASCOT, A NEW CRAG-PIT. BY P H I L I P
CAMBRIDGE.
the foot of Hascot Hill, on the right of the road from Barking to Battisford, is a large excavation locally known as the Flint Pit and much overgrown by herbage. T h e basal six or seven feet of its face consist of fairly large waterrolled Flints in a matrix of quite coarse red sand, with numerous small phosphatic Nodules similar to those found in the basementbed of the Red Crag, having associated teeth of Sharks and fragments of Vertebrate bones. When digging in the lowest part of the pit last spring, I came across shelly sand, containing many complete Mollusca and numerous debris of a typical Crag fauna [Trans, ii, 232] ; these resemble those of the Red Crag basement bed, excepting the much greater abundance of Cretaceous forms, the more worn condition of the derived Eocene fossils, and the total absence of Box-stones. They a r e : Neptunea contraria, Turritella spp., Arctica (Cyprina) sp., Astarte Omali, Laj. and A. IBurtini, Cardium angustatum, C. IParkinsoni and C. (Cerastoderma) edule, Chlamys opercularis, Thais (Nucella) lapillus, and Pectunculus glycemeris.—Further Flints and Red Sand are found in the large pit near Valley-farm, where a much broader face is exposed. But, although this contains numerous phosphatic Nodules and appears in every other way identical with the first mentioned deposit, I have not found in it a single organic fossil of any sort. Halfway across the pit, Red Crag is cut out by a Glacial Channel that is filled with later sands and gravels, extending almost to the Hascot Hill pit. A shallow well was recently sunk, attempting to reach water, in the floor of this second p i t ; and, at a depth of some six feet soft and marly Chalk was Struck, containing abundant fragments of the Polyzoan Onychocella inelegans, Lonsdale. I feel that it is worth calling the attention of Members to these hitherto overlooked pits, as further work upon their contents, both fossil and mineral, may help to throw new light on our Red Crag deposits. FOSSILS FROM THE CRAG.—Recently I have found the following Foraminifera in the Coralline Crag of Sudbourn Park, excepting a few that t u m e d up at Sutton Knoll and are so indicated. T h e names have been taken from the Palaeont. Soc. Monograph, somewhat brought up to date :—Pyrgo ringens, Lam., at both ; Vaginulina lazigata, Rem., Sutton; V. obliqnistriata, J o n . ; Dorothia gibbosa, d'Orb., both ; Textularia sagittula, Defr., var. jugosa, Brady ; Triloculina oblonga, Mont. ; Discorbis near globularis, d ' O r d . ; Nonion Bousana, d'Orb., var. janiformis, Jon. ; Polymorphinafrondiformis, Wood, abundant at S. Park and common at S u t t o n ; Eponidis repardus, F . - M o l l ; Quinqueloculina sp., both ; Guttulina sp., a fistulöse variety.—An excellent example of what may be accomplished among the Red Crag Mollusca and a few odd other groups in no more than f - h o u r ' s collecting is shown by the following from the Neutral-farm pit at Chillesford FOSSILS AT BATTISFORD.—At
