114 GEOLOGY AND PALEONTOLOGY OF THE WEST INDIES. 



The following is Guppy's description of this species : 



"Shell ovate, ventricose; whorls 6-7, destitute of varices, zoned by about 

 16 low spiral ridges; spire short, conic; aperture rather narrow, outer lip 

 thickened, dentate; inner lip sinuate, dentate; columella tortuous, irregularly 

 folded or plaited; callus thin." 



This species is very closely related to Malea ringens Swainson, living 

 in the Pacific Ocean, with which it was confused by Conrad. It appears 

 to have attained adult characters at a somewhat smaller size and to 

 have more delicate sculpture than the recent species, but in other 

 respects to be almost indistinguishable from it. It is interesting to find 

 this type of shell surviving with such slight modifications in the Pacific 

 Ocean, but now quite extinct in the Antillean region, where it was once 

 so widely distributed. 



Malea camura is represented in the Cuban collections by only one 

 cast of the interior, but there can be little doubt of the correctness of 

 the identification. 



Localities. Near Havana, Cuba, station 4292, Wrenn, collector; also 

 Bowden, Jamaica; Haiti; Pontou, Santo Domingo ;and Gatun, Panama. 



Geologic horizon. Oligocene. 



Types. U. S. Nat. Mus., Nos. 115506 and 115507. 



Cyprsea anguillana, new species. 

 (Plate 1, Figures 9 a, 6.) 



The following is a description of this species: 



Shell subellipsoidal, smooth, polished; spire mammiform, with sutures 

 obliterated; aperture narrow; outer lip closely dentate with about 20 tubercles; 

 inner h'p obsoletely dentate well within the* aperture; inner and outer lips 

 pinched or flattened at the anterior end. 



Alt., 25 mm.; diam., 14.5 mm. 



Locality. Crocus Bay, Anguilla, station 6894; the cast of a larger 

 specimen, probably C. anguillana, was found at station 6893, Vaughan. 

 Geologic horizon. Oligocene.

Cyprsea semen, new species. 

 (Plate 1, Figures 10 o, 6.) 



The following is a description of this species: 



Shell small, rotund; surface smooth and polished, but inner layers of shell 

 exhibiting faint, distantly spaced lirations transverse to the axis; outer Up 

 with 22 or 23 evenly spaced denticulations placed well within the aperture; 

 inner lip with 5 denticulations on the anterior half and several obsolescent 

 denticulations on the posterior half; canals short, nearly equal. 



Length, 8.5 mm. ; diameter, 5.8 mm. 



Locality. Angela Elmira asphalt mine near Bejucal, Cuba, station 

 3652; Wiebusch, collector.
