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
