I now proceed to pen a few notes on these fourteen forms whichwe have observed to present more or less perfect terminations totheir shells ; and in doing so I would express the hope that erelong other forms will be met with to enable us more clearly to un-derstand the value of a more complete structure, while at thesame time it may not be too much to express a hope that betterspecimens may yet be found than those we already possess or,through the kindness of friends, have had access to. i\OTES OX THE SPECIES. Pig. 1.—Termination of Ammonites concavus, 1. Ammoxites coxcavtjs, Sowerby, pi. 94, fig. 2. (Fig. 1.) This is a very common shell in the Cephalopoda-bed in Dorsetand Somersetshire, occurring less frequently in the same horizon inGloucestershire. It is a very variable shell; and hence its syno-nyms are unusually numerous. In this district we have usually named it A. sub?adiatus; and it ishere only retained because A. concavus was figured by Sowerby froma specimen obtained from this neighbourhood.
