Zoological study of the European painted top shell Calliostoma zizpyhinum a sea-snail native to European coasts and the Mediterranean Sea. The marine gastropod is presented with a 3mm. scale and a line from apex to outer lip indicating the concavity of the shell spire.

Detail D from figure 26 of the book British prosobranch molluscs: their functional anatomy and ecology by Vera Fretter and Alastair Graham (London, Ray Society, 1962).

Both Graham and Fretter contributed high-quality illustrations to British prosobranch molluscs and artist attribution can be difficult. Graham’s Royal Society Biographical Memoir states that: “Dr Fretter drew the ‘whole animals’, and Graham most of the dissections and histological preparations. She concentrated on the reproductive system, larvae and shore ecology, and he on other aspects.”

Not signed. One of four figures pasted on a single sheet to make up a plate and annotated in ink: ‘Fig 26 To illustrate shell shape. Set across page x6/10’.

Alastair Graham was elected a Fellow of the Royal Society in 1979.
