This paper is mainly intended to be read as supplementary to ‘Roman London; Its Initial Occupation as evidenced by early types of Terra Sigillata’, by Mr. T. Davies Pryce and Dr. Felix Oswald (Archaeologia, lxxviii), and as emphasizing the conclusions reached in that paper by furnishing some additional examples of the Tiberio-Claudian and Claudian styles of decoration found in London. Mr. Davies Pryce has very kindly read the proofs, and suggestions made by him have been incorporated.
