Figure 7J

2013 Paraseraphs texanopsis Garvie , p. 169, pl. 1, figs. 10–12.

Type material. Holotype — UT (Austin) NPL7075. The type measures 53.3 mm in length, with a width of 14.2 mm ( Garvie 2013).

Type locality. 1 km east of Augusta Houston County, Texas [Lutetian] .

Diagnosis. The shell is smooth and slender, with a high, acute apex thinly covered with shell matrix. The posterior canal is mostly straight, running antispirally towards the apex and reflected at termination. The teleoconch has four whorls. The labial callus is well-developed and the labrum is not thickened. The columella is basally bent backward. The labrum does not reach the base of the columella.

Distribution. EOCENE—Lutetian— USA Weches Formation east of Augusta Houston, Texas ( Garvie 2013).

Remarks. Paraseraphs texanopsis is readily distinguishable from other members of Paraseraphs by the strongly recurved and extended anterior canal.
