. Bulletins of American paleontology. Fossil Lep/cythara in Tropical America: Jung 27. 1 3 Text-figure 23.—Lepicythara disciusa Jung. NMB H 13291 Ho- lotype NMB locality 18574: Melujo River, soiuth slope of the east- ern part of the Northern Range, Trinidad. Melajo aClay Member of Springvale Formation. Height mm. width mm. 1, front view; 2, rear view; 3, from right side. 22 opisthocline to strongly opisthocyrt axial riblets. Apex a little pointed. Number of teleoconch whorls up to five, their profile straight on early teleoconch whorls and slightly convex on late whorls. The axial ribs of the first two teleoconch whorls are somewhat pointed at the periphery thus projecting a little over the ab- apical suture. Teleoconch whorls sculptured by eight to ten orthocline to slightly opisthocline axial ribs per whorl. The axial ribs may be alined on successive whorls and those on the body whorl may be somewhat sigmoid. Interspaces of axial ribs concave, sculptured by four incised, spiral lines on the first teleoconch whorl. Their number increases to twelve on the pen- ultimate whorl. There are few secondary incised, spiral lines. All spiral lines cross the axial ribs. Suture shal- low. Aperature narrow. Outer lip thickened. Sinus ad- joining suture moderately shallow. Inner surface of outer lip smooth, in rare cases with an inconspicuous ridge parallel to the slightly crenulated, shaip edge of the outer lip extending from the sinus to the beginning of the anterior canal. Coluniellar and parietal calluses weakly developed. Anterior canal straight, fairly long. /yo/rmy^e.—NMB H 15291 (Text-fig. 23). Dimensions of liolonpe.—Height mm. width mm.
