LiNDSLEYA Reeveana, Chitty. 



Hab. The borders of Manchester, Trelawny and St. Ann's. 



Colour^ pale horn. Sculpture, 7 strong spiral carinse, those about 

 the periphery being more distantly apart, with in each interspace 

 3 finer carinae ; on the upper whorls 4 strong carinas : almost obsolete 

 behind the labrum. Striae of growth slightly visible. Spire, well 

 elevated, with slightly convex outlines. Whorls, 4, well rounded, 

 with a deep suture ; last whorl well rounded and very globose. 

 Aperture, peculiar and very large and spreading, considerably con- 

 stricted far behind the labrum, very much expanding again like the 

 half of the bowl of a spoon ; subangular above and below on the 

 left, depressed above, well dilated on the right below, widest hori- 

 zontally, flattened below. Labrum, at about -|rd of the length of the 

 constriction, attached to the body-whorl, in, as it were, a curvilinear 

 opening of about 35° ; the spiral carinse at the back almost obsolete 

 and striae of growth stronger ; double, the outer edge pectinated by 

 7 points of the stronger carinse and scolloped ; inner edge much 

 thickened, pectinated by about 4 points, much produced and de- 

 flected above, modifying the aperture. Labium, appressed in its upper 

 end to the penultimate whorl, straight above, slightly curved to the 

 right below, very much below the plane of the labrum. Umbilicus, 

 rather deep and very narrow. Labral lamella, very finely produced. 

 Operculum, well thickened on the labial side, very slightly concave 

 and smooth. 



Height 0061, greatest breadth 0-073, least breadth 0*06 1. 



Named in compliment to Lovell Reeve, Esq., the able conchologist. 



LiNDSLEYA Shuttleworthiana, Chitty. 



Hab. Burnt Hill Glade, Westmoreland (unique). 



Form, globose-conic. Colour, ? Sculpture, striae of growth 



very visible, oblique ; about 1 6 strong sharp spiral carinse, stronger 

 below, with one faint finer in each interspace ; on upper whorls 



5 strong, with finer intervening. Spire, slightly and rather con- 

 cavely elevated. Whorls, 5, moderately convex, with a deep suture ; 

 last whorl large and spreading behind the labrum, but, on the left, 

 assimilating the form of the subgenus Metcalfeia, and rather fall- 

 ing off below. Aperture, semicircular, except as modified by the 

 labium ; very slightly spreading. Labrum, thin, slightly reflected, 

 pectinated by about 10 points, 4 fine and close on the upper part, 



6 strong and wide apart round the periphery, strongest at the peri- 

 phery ; above, moderately produced from the body- whorl in a grace- 

 ful curve. Labium, well detached from the body-whorl, curved 

 throughout, below the plane of the labrum at lower end, thickened 

 and reflected towards the umbilicus. Umbilicus, deep and narrow. 

 Labral lamella, very slightly produced and immediately merged in 

 the umbiHcus. Operculum, ? 



Height 0-072, greatest breadth 0*12, least breadth 0-084. 

 Named in compliment to Robert Shuttlevvorth, Esq., of Berne, 

 the well-known botanical and conchological collector and author.
