This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1904 edition. Excerpt: ...It differs in some respects from the type of the species as figured and described by Aldrich, and later refigured by Harris (fig. 4). The chief differences are, according to Harris; the greater number of costae on some of the whorls in the Midway variety where they number as high as eighteen, while in the Lignitic variety seven or eight is the usual number; and the absence of the second incipient carination at the suture in the Lignitic variety, this being a marked feature in the Midway variety from Matthews' Landing. Localities: Alabama Woods Bluff, Matthews Landing, Oak Hill, Dale Branch. Horizon: Lower Eocene, Midwayan and Chickasawan groups. Fig. 5. Falsi-fusus meyeri, Midway variety. FALSIFUSUS LUDOVICIANUS (Johnson). (Plate XVIII, fig. 1.) 1899. Fusus ludovicianus Johnson, Proc. Phil. Acad., p. 72, pl. 4. The protoconch of this species agrees in essential characters with that of F. meyeri. The first two whorls are smooth and gradually increase in size. The next whorl is marked by oblique narrow smooth rib-lets essentially as in F. meyeri. This is followed by the normally round-ribbed and spirally marked whorls, which with but slight modification continue to the adult stage. The shoulder is slightly flattened, but there is no pronounced angulation or carination of the whorl. It is, however, more bulging in the center than is normal in rounded-whorled species of Fusoid shells. Locality: Louisiana, St. Maurice Winn Parish (Johnson); Phil. Acad.--(U. S. Nat. Mus. 147226). Horizon: Eocene, Lower Claiborne. fig. 5-Fig. 6. Folsi-fusus ludovicianus. (After Johnson.) FALSIFUSUS (?) HOUSTONENSIS (Johnson). 1899. Fusus houstonensis Johnson, Proc. Phil. Acad. Sci., p. 72, pl. 1, fig. 4. The apex of the only specimen of this species known is imperfect, ..
