The profile of the teleoconch whorls is the same as in the larger spec- iinen. Both specimens from USGS Station 7873 are bi- conic and moderately slender. Their spiral sculpture consists of fine, incised lines which cross the axial ribs. Specimen PRI 22939 is the specimen desciibed and figured by Weisbord (1929, p. 55, pi. 5, Hgs. 13-14) as Cyiluini lu'pratioiici? (Gabb), which was been collected from an unspecified locality and horizon in Colombia. It is re-figured here under this heading because it is only the third specimen of Lepicythara recorded from Colom- bia, if Oinomikado's (1939, p. 624) undocumented rec- ord of Cyiluira cf. cerciu/lca Maury from southwestein Colombia is not taken into consideration. The proto- conch of this weathered specimen is not preserved. The early teleoconch whorls cairy seven axial ribs per whorl, the body whorl nine.
