400 Rev. M. J. Berkeley and Mr. C. E. Broome on British Fungi. sharp ridges, traversed by distant spiral threads ; and by the flesh-tinted orange colour. Mangelia cerea. M. testa M. hamatee simili, sed textura cerea, aurantiaca, graciliore, anfractibus tumidioribus, haud angulatis ; anfr. nucl. lsevibus; normalibus v., costis radiantibus haud acutis, interstitia sequan-tibus ; liris spiralibus A'alidioribus, haud filosis, supra costas nodu-losis, in interstitiis subobsoletis ; apertura, testa adulta, ? . . . . Long. -25, long. spir. -14, lat. -1, div. 28°. Variat testa rufo-fusca. Hab. Panama (teste Jeweti). Col. Jewett's unique specimen is not mature. It is distin-guished from M. hamata by the smooth nucleus, waxen texture, rounder whorls, more equal distribution of the contour between ribs and interstices, and especially by the spiral sculpture, which is faint in the hollows, but nodulose on the ribs. Mr. Cuming has a specimen with the same texture, but of a rich brown colour. Chemnitzia calata. C. testa satis magna, cinerea, elongata ; anfr. nucl. ?. . . ; norm, xiii., planatis, suturis vix impressis ; costis radiantibus xx.-xxviii., rectis, haud semper convenientibus, subacutis, ad peripheriam subito truncatis ; svdeis spiralibus in spira iv.-v., valde impressis, interstitia et costarum latera transeuntibus, juga baud superanti-bus ; basi subito angustata, angulata, lirulis spiralibus circ. vi. ornata; apertura subquadrata ; columella satis torta. Long. *35, long. spir. -3, lat. -09, div. 13°. Hab. "West coast of Nortb America (Javett). This beautiful and unique shell was probably from Panama ; but there was no locality-mark. It is remarkable for its deep furrows and the suddenly shortened and spirally sculptured base. It is much larger and broader than the northern C. Virgo, and differs in details of sculpture.

On the ground, at the roots of firs. Aboyne, Aberdeenshire; Staunton, Notts. It has also been found near London by Mrs. Lloyd Wynne. The affinities of this curious plant are very doubtful ; for it does not appear to be of the creamy consistence of JEthaliwn in any stage of growth. We have no better opinion, however, to
