We’re all about mollusks in our book of the week this week, with our featured title being one brimming with some really spectacular watercolors by Comingio Merculiano. What, you might ask, is the title of this exceptional work? I Cefalopodi Viventi nel Golfo di Napoli (Sistematica) (1896). While the copy on BHL consists of only the plates from this title, the entire volume (with text) constitutes the 23rd monograph in the series Fauna and Flora of the Gulf of Naples, published by the Stazione Zoologica. This particular monograph, written by Giuseppe Jatta, presents, as the name suggests, detailed information on the Cephalopods of the Mediterranean.
