314 ANTILLEAN FOSSILS— G UPPY AND BALL. vol. xix. 



Oligoceiie of Jamaica, Yendryes (Guppy, 2279). Xo. 107081, n.S.:N\M. 

 This curious little shell iii)pears to be au Aclu, but might possibly be 

 the youiig of a smooth TnrhonilUi. 



Subgenus AMBLYSPIRA, Ball. 



ACLIS ? (AMBLYSPIRA) TERES, Guppy, new species. 



(Plate XX VIII, lig. 6.) 



Elougate-tuniculate, somewhat arcuate, ivory-shining, covered with 

 enamel-like de])osit; whorls about 7, ilattened, except the earlier ones, 

 which are sometimes more or less rounded; suture scarcely distinct 

 except between the earlier whorls; aperture elongate. Alt. 2, lat. 

 O.o mm. [G.] 



Ditrujia bed, rointapier,Trinidad,Guppy (2252). Xo. 107073, U.S.N.M. 

 This ;ind the following species belong to a group of minute shells be- 

 tween Aclis and Eulhna conchologically, characterized by their blunt 

 apex and short base with sub(;ylindric form, which may, however, be 

 varied by the overhang of the whorls. They are rather characteris- 

 tic of deep water, and a number of undescribed recent species have 

 been obtained from 400 or 500 fathoms off* the coast of Florida. The 

 apex resembles that of Eulhua externally, but the shell Inis more the 

 aspect of some of the Aclides. A. teres may be taken as the type, for 

 which 1 propose the subgeneric name Amhlyspira. 



ACLIS? (AMBLYSPIRA) PROMINENS, Guppy, new species. 

 (Plate XXVI I, lig. 11.) 



Subrinuite, conic tiirrited ; whorls about !), strongly carinate ; t\iQ, 

 keel overhanging tlie suture, thereby causing the hitter to be deeply 

 sunk, especinlly on the later whorls; aperture somewhat angulate and 

 forming an obsolete canal above. Alt. 4, lat. 1.5 mm. [G.] 



Oligocene of Jamaica, Vendryes (Guppy, 2271). Xo. 107072, TT.S.N.M. 



ACLIS? (AMBLYSPIRA n doubtful species. 



Subrimate, turrited-cylindric; whorls 4-5, smooth,- slightly convex, 

 carinate at the line of suture; aperture simple, suboval; columellar mar- 

 gin slightly reflected. Alt. 2, lat. 0.5 mm. [G.] 



Ditrupabed,Pointai)ier,Trinidad,(hippy(2272). Xo. 107112, U.S.X.M. 

 These specinuMis are evidently immature, and do not afford material for 

 a complete specific diagnosis. 



EULIMA EGREGIA, Guppy, new species. 



(Plato XXVIII, lij;. 11.) 



Turrited, smooth; whoils about 14, slightly convex; suture well 

 marked, simple, linear; aperture suboval; columella callus reflected 

 over the body whorl. Alt. 20, lat. 10 mm. [G.]
