Shellminute, white, few-whorled, having the surface dis-tinctly sculptured or cancellated. Most of the similarspecies are smooth. This completes our list of theseminute shells. We turn now to a very distinct and well-markedspecies, Conns Californicus, Hds., Ko-nus Cal-i-for-ni-cus. Fig. 36 shows theappearance of a large specimen. Thisis our only representative of the greatCone family which has so many beau-tiful examples in the tropical waters ofthe Pacific and the Indian oceans. Our little species is very humble, being about an inch in length, of a chestnut color, with a smooth surface,. THE CALIFORNIA CONE. 55 though it may occasionally be found covered witha hairy epidermis. Living shells are rare, but deadones may frequently be found, particularly on thesouthern coasts. There is a little black shell named MitromorphaJilosa, Cpr., Mi-tro-mor-fa fil-o-sa, and this nametells us that it has the form of the Miter Shells, andthat its surface is threaded. Please look back to and you will find its shape, pointed at both endsand largest in the middle ; and if you examine it witha lens you will see that it is distinctly marked bymany spiral lines. Its length is only a quarter of aninch. Mitromorpha , Cpr., as-per-sa, is evensmaller than the above, but it has a brownish surfacemarked with a very distinct, sieve-like network offine lines. Mangelia striosa, C. B. Adams, Man-je-li-a stri-o-sa, is a rare southern species
