This is the complete 37th part, with the genera Tridacna, Littorina (with three new species), Turrilites, Turbo (with two plates), Galeomma (one new species), and Trochus. Thus the total is an unusual seven hand-coloured plates instead of the usual six. Apart from this "highly finished in colour" version, sold at 6s[hilling], there was also a plain edition, sold at 4s. Both are rare. Untrimmed. Front cover foxed, otherwise very good, clean. Loose parts in their original printed wrappers are very rare. Nissen ZBI, 3921; R. E.
