1939 Terebellum californicum Vokes , p. 157, pl. 20, figs. 7, 8, 11. Jung 1974, p. 41. Hanna & Hertlein 1949, p. 394.

Type material. Holotype — CAS 608 . The length is 19.3 mm and width approximately 4.7 mm ( Cooper 1894).

Type locality. Rose Canyon , San Diego County, California, USA [Lutetian] .

Diagnosis. The shell is moderately slender, the surface of the shell is smooth and the spire moderately high. The sutures of prior whorls are visible within the canal. The labrum is not thickened and the suture is indistinct. The columella is bent backward near the base.

Distribution. EOCENE— USA Rose Canyon, San Diego County, California ( Jung 1974). Lutetian/Bartoni- an— USA California Media Creek area, Kern County, California (‘Mallory’ in Jung 1974). Trinidad Boca de Serpiente Formation of Soldado Rock ( Jung 1974). Lutetian— USA Kern County, California ( Hanna & Hertlein 1949). Domengine Beds, California ( Effinger 1938).

Remarks. The holotype of P. erraticus ( Cooper, 1894) is an incomplete shell lacking the base ( Jung 1974). It is comparable to P. californicus ( Vokes, 1939) , and they are herein considered the same species ( Jung 1974).
