In Fig. 8, Plate XXVIII, a very handsome specimen from a refuse heap on Blennerhasset Island, Ohio River, is shown. It has been cut from the columella of a _Busycon perversum_, the reverse whorl being indicated by the well-preserved spiral groove, and was suspended by means of a small, well-made perforation near the upper end. The surface is weathered and chalky with age. Another specimen, from the same locality, differs but slightly from this; the perforated end is broken away; the surface is deeply weathered, and the more compact laminæ stand out in high relief. Two specimens from Sarasota Bay, Fla., resemble these very closely in shape and size; instead of a perforation, however, they are grooved near the upper end. They are made from the columellæ of the _Busycon perversum_. One of them is shown in Fig. 9, Plate XXVIII. It is possible that a number of the small shells usually supposed to be perforated for use as ornaments have been used for sinkers. One such specimen, collected by Professor Velie in Florida, is preserved in the national collection. It is made from an almost entire specimen of a small but compact univalve--a dextral-whorled _Busycon_ or a _Strombus_. A shallow groove has been cut near the basal point for the purpose of attaching a line. A fourth specimen, from Florida, is represented by a cast presented by Professor Velie; it is three inches in length and nearly one inch in diameter, and has been derived from the columella of a _Busycon perversum_. It has a broad groove near the upper end, with a long, sloping shoulder, the body being somewhat conical below. Other specimens of similar character have recently been added to the national collection. A grooved specimen of medium size was obtained from a mound at Madisonville, Ohio, and is figured by the explorers.[45] A few smaller specimens come from New York, and others from Kentucky, but they were probably intended for ornaments, and as such I prefer to class them. From the Pacific coast we have a large number of examples, one of the finest being illustrated in Fig. 7, Plate XXVIII. It is a flattish, somewhat pear-shaped pendant, and has a neatly cut groove near the upper end. It was collected by Bowers on the island of Santa Rosa, Cal., and was probably made from a _Pachydesma_ or _Amiantis_. A new-looking specimen from Santa Barbara, carved from a flat bit of pearly _Haliotis_, represents a fish, the mouth, gills, body, and tail being distinctly shown. It may have been used as a bait.
