In the manufacture of these vessels the _Busycon perversum_ seems to have been a great favorite; this may be the result of the less massive character of the shell, which permits more ready manipulation. The spines are less prominent and the walls more uniform in thickness than in shells of most other varieties found along the Atlantic seaboard. Specimens of the _Strombus_, _Cassis_, and _Fasciolaria_ were occasionally used. The specimen illustrated in Fig. 1, Plate XXII, is from a mound at Ritcherville, Ind., and is now in the National Museum at Washington. It is made from a _Busycon perversum_, and is ten and one-half inches in length by six and one-half in width at the most distended part. The body and spire have been cut in the manner described above, and the interior whorl and columella have been skillfully taken out. The rim is not very evenly cut, but is quite smooth. The outer surface of the shell has been well polished, but is now worn and scarred by use. The substance of the shell is very well preserved. A second example, now in the national collection, is from an ancient mound at Naples, Ill. It is very similar to the preceding, being made from the same species of shell. It is eleven inches in length by seven in width. The body of the shell is well preserved, the apex, however, being broken away. A small specimen, also in the National Museum, was obtained from a mound at Nashville, Tenn., by Professor Powell. It is three and a half inches in length, and very shallow, being but a small portion of the lower whorl of a _Busycon_. [Illustration: PL. XXII--VESSELS. 1.

(3/4)] Among the more recent acquisitions to the national collection are two very fine specimens of these _Busycon_ vessels. One of these was obtained from a mound at East Dubuque, Ill. It is eleven inches in length by seven in width at the widest part; the exterior surface is highly polished; the interior is less so, having suffered somewhat from decay; the beak is very long and slender, and has been used as a handle. The whole vessel has a dipper-like appearance.
