Aperture, less than a semicircle, slightly expanded in the lower two- 

 thirds, slightly ohlique. Labrum, unequally and not strongly pec- 

 tinated by the spiral carinae, very slightly produced above. Labium, 

 well detached from the body-whorl, attached to labrum above in a 

 slight curve, very slightly waved in its centre, and well curved to 

 the right below. Umbilicus, moderately deep, and labral lamella 

 moderately produced. Operculum, ? 



Height 0-072, greatest breadth 0*12, least breadth 0'079. 



Named in compliment to Dr. P. Sutherland, the Arctic voyager,

Metcalfeia Morchiana, Chitty. 



Hab. Roaring River, Westmoreland. 



Form, depressed conic. Colour, very pale horn. Sculpture, 5 

 strong spiral carinse, 1 fine ; 7th strong and 3 fine ; 8th to 1 5th 

 strong and 1 fine intervening each ; on the upper whorls 8 strong. 

 Spire, slightly elevated with concave outlines. Whorls, 4f, very 

 slightly rounded with a light suture. Aperture, slightly expanded, 

 more below than above ; slightly produced, abruptly from the penult 

 whorl : more than a semicircle. Labrum, thin, and very slightly 

 reflected ; pectinated by the strong carinae. Labium, on a plane 

 with the labrum above, lower below ; joining the labrum with a curve 

 above ; much curved to the right, below well detached from the 

 penult whorl. Umbilicus, narrow and deep. Labral lamella, well 

 produced above and rather wide below. Operculum, moderately 

 concave in the middle, with a wide border on the labial side, which 

 is vertically grooved and again crossed by four or five raised horizontal 

 plaits : labral side with about eight short horizontal lamellae, about 

 four extending across the hollow, and a linguiform point at the lower 

 extremity of the labial side overlapping the labium. 



Height 0072, greatest breadth 0'1, least breadth 0'074. 



Named in compliment to M. Morch, of Copenhagen, distinguished 

 for his knowledge of Mollusca. 



Metcalfeia Verreauxiana, Chitty. 



Hab. 1 Hanover. 



Form, depressed conic. Colour, pale horn or yellow. Sculpture, 

 17 strong spiral carinas with 1 fine intervening each. On the upper 

 whorls 5 strong with 1 fine intervening. Spire, moderately elevated, 

 with straight outlines. Whorls, 4-i, moderately rounded, with a 

 light suture. Aperture, scarcely separated from the body-whorl, 

 more than a semicircle, large, rather expanded and depressed below. 

 Labrum, very slightly produced above, strongly and prominently 

 pectinated by the strong carina), imbricated in those round the peri- 

 phery, white and shining. Labium, slightly rounded into the labrum 

 above, and on the right below ; very slightly reflected ; on a plane 

 with the labrum above, lower below ; very slightly detached from 

 the body-whorl. Umbilicus, deep and narrow. Labral lamella, 

 sharp and very slightly produced. Operculum, moderately concave, 

 with large coarse granulations on the upper part of the labial side,
