A HISTORY OF WARWICKSHIRE A magnificent skeleton of the species last mentioned was obtained at Stockton in 1898,' and is now in the British Museum. The plesiosaurs, as represented by the genus P/esiosaurus in the Lias, differ by the rela- tively smaller size of the head, the longer neck, and the more normal form of the bones of the paddles, as well as by many other structural features. The writer has not met with any account of the species found in the Warwickshire Lias. The next horizon in the county where vertebrate remains of any importance have been recorded is a Pleistocene deposit of alluvial silt at Little Lawford near Rugby, from which bones and teeth of mammals were brought to the notice of the late Dean Buckland in 1815. The deposit appears to run continuously along the Avon valley from Rugby to Tewkesbury in Gloucestershire. The following species (with certain emendations of nomenclature) were recorded from Lawford by T. G. B. Lloyd 1 in 1870, namely the Pleistocene variety of the spotted hyaena (Hycena crocuta spelcea), the wolf (Cam's lupus), the Pleistocene bison (Bos priscus], the red deer (Cervus elapbus), the reindeer (Rangifer taran- dus), the Pleistocene race of the hippopotamus (Hippopotamus amphibius major], the wild boar (Sus scrofa), the wild horse (Equus cabal/us fossilis), the woolly rhinoceros (Rhinoceros antiquitatis), the mammoth (Elephas primigenius) , and the straight-tusked elephant (E. antiquus). Assuming all the species to be correctly determined, the list is of special interest as showing the association in the same area of forms now so widely separated as the reindeer and the hippopotamus. 1 See Report Rugby School Nat.
