Terebellum papilliferum Martin, 1916

Figure 8F

1916 Terebellum papilliferum Martin , p. 248, pl. 2, figs. 51–52. Jung 1974, p. 43, pl. 13, figs. 7–11.

Type material. Lectotype — RGM St10339 ( Jung 1974). The type measures 28.0 mm in length with a width of 8.3 mm ( Martin 1916).

Type locality. Gunung Spolong , West Progo Mountains, Java, Indonesia [Burdigalian] .

Diagnosis. The fusiform shell is moderately slender, with a blunt teleoconch and a smooth surface. The columella is nearly straight, and the suture is well-defined. The columella callus continues as a carina above the suture. The labrum is slightly thickened and without a stromboidal notch.

Distribution. MIOCENE—Burdigalian— Indonesia Gunung Spolong, West Progo Mountains, Java ( Jung 1974).

Remarks. Distinguishing T. papilliferum from T. terebellum can be problematic, and it may be a synonym of that species. Jung (1974) noted that this species was similar to Terebellum terebellum , but reserved judgment on validity until further material became available. The Martin (1928) specimen from the Early Pliocene classified as T. papilliferum is probably a representative of T. terebellum . Sepkoski (2002) gave the Thanetian to the Holocene for the geological range for Terebellum , but there is no evidence for this clade below the lower Miocene. Jung (1974) proposed the unknown ancestor of T. terebellum arose in the regions of India or Pakistan during the late Oligocene.
