Mr. Morris, in his Memoir on the Deposits containing Mammalia in the Valley of the Thames (Magazine of Natural History, Oct. 1838), presents a variety of information bearing on the contemporaneous races of mammalia and mollusca. The mammalian remains are of the 'diluvial' æra (elephant, rhinoceros, hippopotamus, horse; ox; deer, Irish elk; vole, bear, lion, hyæna,—occurring at Brentford[1], Wickham, Ilford[1], Erith, Grays, Whitstable, Copford, Stutton, Harwich, Gravesend, Nine Elms, Lewisham, Kingslands. The shells found at Erith, Grays, Copford, Stutton and Ilford, are thus enumerated:—
Cyrena trigonula, at Ilford, Erith, Grays, and Stutton.
Cyclas obliqua, Stutton; C. cornea, Stutton, Grays; C. pusilla, Stutton.
Pisidium amnicum, Stutton.
Anodon cygneus, Grays, Stutton, Erith.
Unio pictorum, Grays, Erith, Ilford; new species Erith (examined by Mr. G. B. Sowerby).
Succinea amphibia, Grays, Stutton; S. oblonga, Ilford.
- ↑ 1.0 1.1 Mr. Morris remarks that the shells which occur at these localities are of land and freshwater kinds, not marine, and agrees with the opinions of Mr. Charlesworth. that mammalian remains are more commonly associated with fluviatile and lacustrine, than marine and detrital deposits, a conclusion which is acquiring fresh importance every day. We have, in fact, preglacial and post glacial elephantine remains.
