Hammetts Branch (L. C. J. and V.).

Stratum 2, Natchitoches (V.),

New species of corals belonging to the following genera have been discovered in the Lower Claiborne of Louisiana:

Making a total of twelve species of corals plus one variety.

In stratum 2 at Natchitoches indeterminable fragments of a Balanophyllia and a Eupsammia were found.

JACKSON SPECIES.

Creole Bluff is the only place from which a large collection of Jackson fossils was made. Mr. L. C. Johnson made the first collection. I made the second. I collected all of the species listed except Cassidaria petersoni and the Zeuglodon bones which were presented to the United States Geological Survey.

Scaphander grandis Ald. Very large specimens.

Terebra cf. polygyra Con. A small, slender species, consisting of about 12 whorls, marked longitudinally by numerous small costæ; an impressed revolving line slightly anterior to the suture. Canal curved. The sculpture is too fine for T. tantula. It is close to T. polygyra Con. and T. texagyra Harris. The form and longitudinal sculpture are about the same as those of the former species, but the line below the suture is not so much impressed and is nearer the suture. It differs from T. texagyra by having finer costa, and the line below the suture is not as much impressed. I have only one specimen, and that does not fit any species precisely; apparently it is nearest T. polygyra.

Conus tortilis Con.

Conorbis alatoides Ald.

Pleurotoma rotadens Con.

americana Ald.

(Ancistrosyrinx) columbaria Ald.

Mangilia meridionalis Mr.? Probably this species. Without seeing the type I can not make a positive identification.

Bull. 142- -4

Borsonia ludoviciana sp. nov.

Eucheilodon creno-carinata Hpn.

Cancellaria, 2 sp. = C. plicata, Lea ? and C. mississippiensis Con. ?

Phos cf. hilli Harris. This species is slightly larger than P. hilli; its longitudinal folds are more prominent and less numerous (from 6 to 8 on the body whole, while in P. hilli there are about 10); spiral sculpture not so pronounced. Every one of these characters is subject to variation, so the species may be, and probably is only a variety of P. hilli.

Phos johnsoni sp. nov.

Cassidaria petersoni Cou.

Calyptraphorus velatus Con.

Aporrhais (Platyoptera) extenta Con. Represented by a fragment only.

Turritella arenicola Con.

alreata Con.

clevelandia Harris.

Solarium alveatum Con.

elaboratum Con. var. acutum Con.

sp. near elaboratum, but has two elevated revolving lines within the umbilicus, and constitutes at least a distinct variety.

sp. nov. A small species grouping with elaboratum. The specimens are not very good.

bellastriatum Con.
triliratum Con.

Serpulorbis granifera Say.

Xenophora humilis Con. (= Xenophora reclusa Vaughan, not Conrad, in Am. Geol.,

Avicula sp. Represented by fragments, probably A. claibornensis Con.
Pinna sp. Represented by fragments, probably P. argentea Con.

Navicula cuculloides Con.

Limopsis radiatus Mr.

Pectunculus filosus Con.

Nucula meridionalis Mr.

magnifica Con. A small variety or young specimens.

Leda multilineata Con.

Fenericardia planicosta Lam.

jacksonensis Con.

parra Lea. var.
The specimens have only 17 ribs, a smaller number than
is typical for the species. They are identical with a specimen in the
United States National Museum from Cornish Ferry, Saline River,
Arkansas, and labeled by Prof. G. D. Harris V. parva Lea.

Meretrix mississippiensis Con.

sobrina Con.

mortoni Con.

Alveinus minutus Con.

Crassatella flexura Con.

Corbula bicarinata Con.

Cardium nicoletti Con.

Astarte parilis Con.

Lucina smithi Mr. ?

choctavensis Mr.

Tellina cf. vicksburgensis Con.

Teredo mississippiensis Con.

Flabellum cuneiforme Lons. var. wailesii Con.

Turbinolia pharetra Lea var.

Trochocyathus lunulitiformis Con.

Balanophyllia irrorata Con.

Endopachys maclurii Lea var. triangulare Con.

Besides these corals there are new species belonging to the following genera:

1 n. gen., including 1 n. sp. belonging to the Turbinolidæ and related to Platytrochus in the character of the columella.

From a locality about 2 miles north of Rosefield, near the Catahoula-Caldwell parish line, the Louisiana geological survey has a small collection of Jackson fossils. The fossils were embedded in an indurated shell agglomerate. By breaking them out a sufficient number was identified to determine the horizon. The following is a list of the species:

The following are the localities in Louisiana from which Zeuglodon bones have been reported:

1. Tullos, Catahoula Parish, from a cutting on the railroad between Alexandria and Monroe (Lerch and Vaughan).

2. Montgomery, Grant Parish (Hopkins).

3. Grand View, on the Ouachita River (Hopkins).

4. Where the Harrisburg and Columbia road crosses the Catahoula-Caldwell parish line (Hopkins).

VICKSBURG SPECIES.

I have seen Vicksburg fossils from only one locality in Louisiana, viz, about 3 miles south of Rosefield, in Catahoula Parish (Lerch and Vaughan collectors). The species collected are:

Dentalium mississippiensis Con.
Ostrea vicksburgensis Con.

Pecten poulsoni Morton.

Arca mississippiensis Con.

Byssoarca lima Con.

Pectunculus arctatus Con.

Crassatella mississippiensis Con.
Meretrix sobrina Con.

Balanophyllia caulifera Con.

Orbitoides mantelli Morton.
