LECTOTYPE: The lectotype is BMNH C51068 , the original of Forbes , 1846: pl. 11, figs. 7a, b, from the Valudavur Formation of Pondicherry, south India, designated by Kennedy and Klinger, 1977: 182.

DESCRIPTION: There are four fragments all belonging to the same individual ( USNM 445420) (fig. 4C–K, R). This material includes a nucleus 9 mm in diameter (fig. 4H– K) enclosed by a whorl fragment with a whorl height of 13.2 mm (fig. 4E–G), a mold of a septal lobe (fig. 4C, D), and a septate fragment (fig. 4 R). The coiling is involute with a small, deep umbilicus. The whorl section is equidimensional and reniform; the umbilical shoulder is inclined outward and the flanks and venter are broadly and evenly rounded. Internal molds are smooth. The suture is imperfectly exposed; it is deeply and intricately subdivided as is typical for the genus. The external saddle is typical for the species and there is a massive septal lobe.

DISCUSSION: Differences between Pseudophyllites indra and other species of the genus are discussed by Kennedy and Klinger (1977) and Kennedy (1986a). The whorl section, septal lobe, and form of the external saddle all indicate that these fragments belong to the type species, P. indra .

OCCURRENCE: The Navesink specimen is from the lower phosphatic layer at Atlantic Highlands, New Jersey. Elsewhere in the United States, P. indra occurs as a rarity in the upper Campanian Nacatoch Sand in northeast Texas, in the lower Maastrichtian Nostoceras (N.) alternatum zone in the Nacatoch Sand in southwest Arkansas, and in the Maastrichtian Prairie Bluff Chalk in Alabama. Outside the United States, the species may appear in the upper Santonian, but is mostly known from the lower Campanian to upper Maastrichtian. There are records from south India, Zululand and Pondoland ( South Africa), Madagascar, western Australia, Japan, Sakhalin, Alaska, British Columbia, California, Brazil, Chile, northern Ireland, southern Sweden, Poland, Austria, and southwest France.
