Tertiary beds of iMonserrat, Trinidad, Gnppy (2282). ISTo, 107082, 

 n.S.ISr.M. A remarkably fine large species with exceptionally cou- 

 spicuous sutures. 



EULIMA (LIOSTRACA) NOBILIS, Guppy, new species. 

 (Plate XXX, fig. <J.) 



Very elongate, subulate; whorls 10 or more; spire vsharp (imperfect 

 in our specimens); suture not visible; aperture oblong, narrow, widen- 

 ing anteriorly; body with a callus extending to the slightly reflected 

 but sharp pillar lip. Alt. 7, lat. 2 mm. [(>.] 



Oligocene of Jamaica, Vendryes (Guppy, 2132). No. 107071 U.S.N.M. 



EULIMA, doubtful species. 



Elongate, subulate; whorls 8 or 9; spire sharp; suture masked by 

 enamel; aperture elongate, with a callus on the body. Alt. 4, lat. 1 

 nm). [G.j 



Ditrupa bed, Pointapier,Trinidad,Guppy (2133). No. 107111,U.S.N.M. 

 Probably young specimens of E. noMUs, but if not, too imperfect for 

 description. 



PYRAMIDELLA (LONGCH^EUS) JAMAICENSIS, Dall, new species. 

 (Plate XXIX, .10.) 



Shell small, subcylindrical, with 7 or 8 whorls, smooth, polished, 

 with a deep, square-cut channel at the periphery, the bottom of which 

 is crossed by transverse, elevated lines in harmony with the lines of 

 growth; the suture is wound aoout the shell a little in advance of the 

 periphery near but not at the groove, giving the effect of duplication; 

 base rounded, smooth; a strong plait encircles the pillar and emerges, 

 some distance from the aperture, a minor fold is seen on the anterior 

 part of the pillar, but does not emerge; aperture at the base of the 

 pillar angular, almost channeled; outer lip sharp, not lirate inside. 

 Lon. 3.25, lat. 1 mm. 



Oligocene of Jamaica, Bowden marl. No. 115642, U.S.N.M. This 

 species is smaller than any of the others from the same region and has 

 a much stronger peripheral groove in proportion to its size. 



PYRAMIDELLA (LONGCHiEUS) FORULATA, Guppy, new species. 

 (Plate XXVIII, fig. 13.) 



Elongate, ovate-conic, smooth; whorls about 7, with a single square 

 groove along the line of suture; aperture suboval; columella strongly 

 twisted with three folds or plaits; a square, spiral groove runs along 

 above the suture just where it is joined to the succeeding whorl, 

 jjroducing the appearance of a squarely sunk suture. Alt. 5, lat. 

 2 mm. [G.]
