the first and second above extending one-third across only, the lowest 

 slightly curved downwards. 



Height 0-073, greatest breadth 0-096, least breadth 0-079. 



Named in compliment to W. Metcalfe, Esq., the possessor of a 

 fine cabinet of shells. 



Metcalfeia Baquieana, Chitty. 



Hab. Near "The Cave," high road, Westmoreland. 



Form, depressed conic. Colour, rich brown, fading into faint yel- 

 low and white. Sculpture, 1 9 spiral carinse, with one fine intervening 

 each pair. On the upper whorls 6 carinse. Spire, moderately and 

 rather concavely elevated. Whorls, A\, slightly rounded with a 

 lightly impressed suture. Aperture, slightly expanded, shortly and 

 roundly produced from the penult whorl, scarcely depressed ; sub- 

 semicircular, rather dilated above. Labrum, pectinated by all the 

 stronger carinse, slightly scolloped. Labium, slightly detached from 

 the penult whorl, rather abruptly detached from the labrum above 

 and curved below to the right, much lower than the plane of the 

 labrum below. Umbilicus, not deep. Labral lamella, expanded 

 above, narrow round the umbilicus. Operculum, concave in the 

 middle, seven lamellae radiating horizontally from the labial side, one 

 short and central above, one (the longest) crossing the hollow, one 

 short on the labral side, one longer (second in length), one short, 

 and two longer (third in length) below. 



Height 0-06, greatest breadth 0-089, least breadth 0-071. 



Named in compliment to my bosom friend, Mons. Baquie, of 

 Westmoreland, Jamaica. 



This shell is closely allied to Metcalfeia Chittyana at first glance, 

 but differs in many minute particulars ; the pectination on the 

 labrum is alone sufficient to distinguish it ; and their habitats are 

 about sixty miles asunder. The spire is more conical than in M. 

 Chittyana, spiral carinse more distant, labium less widely detached 

 from penult whorl, upper part of labrum more produced, apex is more 

 blunt. In 31. Chittyana the labral lamella expands suddenly above 

 close to where it leaves the labium, rising above the plane of the 

 aperture, and then descending round the umbilicus in a uniform 

 curve without projecting ; in 31. Baquieana it does not rise above 

 the plane ; but after leaving the labium, it spreads out towards the 

 centre of the umbilicus, and continues uniform till it is lost in the 

 umbilicus. In the former the lower end of the labium is on a plane 

 with the labrum, in this it is below the plane. In this, the aperture 

 is larger and more oblique, and the last whorl is less expanded. 



Metcalfeia Sutherlandiana, Chitty. 



Hab. Belmont, St. James. 



Form, depressed conic. Colour, very pale horn or white. Sculp- 

 ture, lines of growth visible ; 1 9 rather strong inequidistant spiral 

 carinae, with an unequal number of finer ones intervening. On the 

 upper whorls 5 carinae. Spire, moderately and rather concavely 

 elevated. Whorls, 5, moderately elevated, with a deep suture.
