KinvertiA Formosa, Lyc. Tab. XLIV, fig. 5. 
Testa parva subulo-pupeformi, anfractibus (6 ?) latis, planatis, suturis bene distinctis, 
costis longitudinalibus rectis (circa 7 in ambitu) rotundis, depressis, inferne evanescentibus ; 
Lineis transversis (circa 7) regularibus, elevatis ; apertura parva suborbiculari, labris inte- 
gris, simplicibus. 
Shell small, elongated, pupzeform or lessening at both the extremities, volutions (6?) wide, 
flattened or very slightly convex, the sutures well impressed, aperture small, suborbicular ; 
the lips continuous without undulation ; longitudinal coste (about 7) straight, rounded, 
and but slightly elevated, indistinct upon the latter volutions, knotted where they are 
crossed by encircling lines, of which each volution has about seven, regular and conspicuous ; 
the costz are not continuous, neither do their extremities exactly correspond at the sutures 
of the successive volutions, they are more prominent upon the upper half of each volution ; 
the apex is imperfect, the first volution having disappeared. 
Allied to Kilvertia strangulata=Cerithium strangulatum, D’Arch., from which it is 
distinguished by the smaller dimensions, the greater elongation of the spire, and by the 
costze, which are much smaller, more depressed, and do not form continuous elevations, 
Geological Position and Locality. Collected by E. Witchell, Esq., in the white (Great) 
Oolite of Bussage, near Bisley Common. 
AMBERLEYA CAPITANEA, Goldf., sp. Tab. XLL fig. 1. 
Part I, p. 65, contains a correct description of this species (Zwrbo capitaneus, Goldf.), 
which is not uncommon in the Supra-liassic sands and the Inferior Oolite of the southern 
counties ; Mr. Walton has also forwarded two small examples obtained in the Forest 
Marble of Laycock, and of Pound Pill. The shell figured Tab. IX, Part I, fig. 33, was 
referred doubtfully to this species, of which it was supposed to be a badly preserved 
example ; subsequent examinations of other specimens from the same locality have proved 
that this view was erroneous, and that it is a distinct species ; a description of this latter 
shell will be found in this Supplement (p. 19) under the title of Amberleya Jurassi. 
AMBERLEYA MONILIFERA, Lyc. Tab. XI, fig. 10. 
Testa parva, ovato-elongata, spira alta, acuta, anfractibus (4—5) in medio carinatis, 
tabulo-nodiferis, postice et antice concavis, ejusdem carina parva, nodifera ; anfractu 
ultimo basi sulcis quinis, concentricis, apertura antice subcontracto. 
Shell small, ovately elongated, spire elevated, acute, consisting of four or five volu-
