In the Thirty-Sixth Annual Eeport on the New York State Museum of Natural History (8vo. Albany, 1884), is a folding plate with a fly-leaf descriptive of a specimen with peculiar structure from the Calciferous Sandstone group of Greenfield, Saratoga Co. referred to a new genus and species under the name of Cryptozoon proliferum, but no author's name appeared to either the plate or the description. The peculiar appearance of the American figure reminded Prof. Eupert Jones of a specimen in his collection, and having kindly placed it in ray hands and permitted me to bring it before the notice of the readers of the Geological Magazine, he has given it to the British Museum. Prof. Jones's specimen was collected by the late John Calvert, F.G.S., the author of “Vazeeri Rupi, the Silver Country of the Vazeers in Kulu,” and the rock is referred to at p. 8 of that book. The specimen was shown by Mr. Calvert to Sir Warington W. Smyth (whose opinion as to its inorganic nature is quoted by Mr. Calvert), and afterwards given to Prof. Jones.
