Reeve says of his shell. “I am not quite sure that this is the T. sanguineus of Linnæus, but _have every reason_ to believe it is.” That is, every reason except the one only convincing proof, which was so easy to a London naturalist, an inspection of the original type in the Linnæan Collection. A mere glance at this would have exposed his error. Reeve’s shell is whitish, with blood-red spots, and is probably a S. African species. Whether Linnæus described from Mediterranean or Japanese specimens, cannot be told from his rubbed shells; nor as yet have sufficiently perfect specimens been compared from the two oceans; but no character has been observed by which they can be separated. The great author obtained his Algerine and his Philippine shells from the Swedish consuls; and Japanese species may have been mixed with the latter. It is very rare in the Mediterranean; common in Japan; common also at Vancouver; but rare further south. It is, we believe, the only Californian shell described by the father of modern Natural History. The specimens vary very greatly in strength of sculpture. There is also a purple variety. _Leptonyx_ (_sanguineus_, var.) _purpureum_. H. t. ‘H. sanguineo’ simili, sed purpureo fuscâ; lirulis spiralibus crebioribus, interstitiis parvis, labio obsoleto. _Hab._ Sta. Cruz, _Rowell_. Monterey, _Cooper_. Neeah Bay, _Swan_. _Leptonyx bacula_, Carp. L. t. “L. sanguineo, jun.” simili; sed rufocinereâ, sculpturâ obsoletâ; anfr. iv. planatis, suturis vix distinctis, marginibus spiræ valde excurvatis; lirulis obsoletis latioribus, et circa basim striis crebris, vix sculptâ; apertura rotundatâ, declivi; columellâ vix callosâ. Long. 0.08, long. spir. 0.06; lat. 0.14. _Hab._ Catalina Is., dead on beach; _Cooper_, No. 1056. This unpretending little shell resembles on the back one of the small Helicinæ. It differs from L. sanguineus in its small size, ashy color, flattened sutures, and nearly obsolete sculpture. A groove in the somewhat callous columella, continued slightly round the labrum, seems intended for the broad-margined operculum of the genus. ANNUAL MEETING, JAN. 9TH, 1865. President, Col.
