_a._ Portolano in the British Museum, bearing date 1536. _Index to MSS. in British Museum_, 19,927. If this is the one Kohl (_Discovery of Maine_, p. 293) refers to as no. 5,463, MS. Department British Museum, it is signed and dated by the author. _b._ Portolano, dated 1536, in the royal library at Dresden, of ten plates,—one being the World, the western half of which, showing America, is given reduced by Kohl, p. 292. It resembles XVII. 33, above, but is not so well advanced, and retains a trace of Verrazano’s Sea, which makes New England an isthmus. It wants the California peninsula, a knowledge of whose discovery had hardly yet reached Venice. _c._ Portolano, in the Bodleian Library, Oxford; thought by Kohl, who gives a sketch (pl. xv. c), to be the work of Agnese, since it closely resembles, in its delineations of the American continent, that Venetian’s notions. This, perhaps, is earlier than the previous map; for it puts a strait leading to the Western sea, where Cartier had just before supposed he had found such in the St. Lawrence. _d._ Map in the archives of the Duke of Coburg-Gotha, marked “Baptista Agnes fecit, Venetiis, 1543, die 18 Febr.” Kohl (pl. xvii. 3) gives from it a draft of the eastern coast of the United States. _e._ Map, like _d_, in the Huth Library at London. _f._ Portolano in the Royal Library, Dresden. It shows California. Kohl, p. 294. _g._ Portolano in the British Museum, dated 1564. _Index to MSS._ 25,442. Kohl says (p. 293) there are other MS. maps of Agnese in London, Paris, Gotha, and Dresden, not here enumerated. A few other books, less extensive and more accessible, deserve attention in connection with the study of comparative early American cartography.

The maps are unfortunately on a very much reduced scale. * * * * *
