 EuLiMA (?) FULVO-ciNCTA. Shell ovatc-conic, turrited : translu- 

 cent, white, with a spiral band of bright brown below the middle of 

 the whorls, and another along the suture, both of which bands are 

 much and irregularly interrupted ; with a kw transverse irregular 

 stripes of the same: smooth and shining : apex rather obtuse : spire 

 with the outlines nearly rectilinear : whorls seven, planulate, with an 

 indistinct suture: aperture narrow: columella subtruncated. 



Mean divergence about 20"^ ; length .2 inch ; breadth .065 inch. 



Natica PRoxiMA. Shell obliquely ellipsoidal : mostly fawn color, 

 or livid, white anteriorly, and on the callus, with an ill defined dingy 

 white stripe next below the suture ; anteriorly with a circle of trans- 

 verse curved brown flames; above the middle of the last whorl, with 

 a narrow pale revolving stripe, on which are rather distinct sagittate 

 spots of dark brown ; sometimes next below the middle is a similar 

 but more faintly and closely spotted line : thin, smooth, and shining, 

 with the oblique infrasutural striae rather feeble : apex subacute : 

 spire prominent, with the outlines moderately curvilinear : whorls 

 five, quite convex, with a well impressed suture : aperture not very 

 wide, ovate but compressed in the left outline : labial deposit rather 

 thick, but subtransparent : umbilical callus about half filling the um- 

 bilicus in the lower and right side : umbilicus rather narrow, deep, 

 partially concealed by the labial deposit. 



This species resembles the young of N. canrena, but the spire is 

 longer ; the aperture is narrower, and the form consequently not 

 ovate : the umbilical callus is rather smaller ; the shell is thinner : 

 the plan of coloring, although similar, is constantly different. 



Mean divergence about 120° ; length of aperture about .52 inch ; 

 total length .7 inch ; breadth .6 inch. 



Natica Jamaicensis. Shell obliquely ellipsoidal : pale brown or 

 livid, somewhat mottled, often with three more or less distinct revolv- 

 ing series of transverse curved brown flames ; with a white spiral in- 

 frasutural stripe ; with the umbilical callus and most of the labial de. 

 posit dark brown : with obsolete spiral striae ; with the oblique infra- 

 sutural striae quite distinct: apex acute: spire prominent, with the 

 outlines moderately curvilinear : whorls nearly five, rather convex, 

 with a well impressed suture : aperture not very wide, ovate but
