Dark Blue Staffordshire Pottery

Have three pieces DOGS WITH SPOTS, impressed crown Ralph & James CLEWS. It came to me as two handleless cups and an impressed saucer. Since then I found a very similar waste bowl with floral border-only, poinsettia and acanthus leaves measuring 6 ¼” across.

My question is about the pattern name, which is in the Transferware Collectors Club database is attributed to STEVENSON. Is it part of a quadrapeds or sporting series? Only the saucer is impressed. The cups and waste bowl have numbers or letters in script. One of the tea cups is larger (sugar bowl?).
