REPORT ON THE GASTEROPODA. 399 



reflected ; it is thickened within, and has very near its edge teeth in groups of 3, 2, 2, 3, 

 so placed as to avoid the longer spirals of the external sculpture. Inner Up spreads some- 

 what thinly and with a slightly disconnected edge across the body ; it then runs straight 

 down the middle of the pillar ; at the top of the mouth a long, somewhat subdivided, and 

 upward-curved tooth defines the canal ; below this there are about nine not very definite 

 teeth on the body ; below the last of these is a wider break, and below this on the pillar 

 are about six more, rather strong at first, but steadily becoming smaller ; parallel to the 

 edge the reverted flap of the lip is prominent below the callus glaze, and finally stands 

 out beyond this glaze as a margin to the canal. H. 2'1 in. B. 1'44. Penultimate whorl, 

 height 0'45. Mouth, height to point of canal 1% breadth from edge of callus 07. 



This species, better than any I know, forms a link between the crumcna and granifera groups of 

 Eanella. It is very near Ranclla nobilis, Eeeve ; but the form there is much broader, and the system 

 of tubercles quite different. Eanella ajjinis, Brod., is very like ; but in that the form is much more 

 regularly conical, the suture, so far from being impressed, is run up on the preceding whorl, the 

 varices run down in straight regular succession, the apex is ruddy purple, and the pillar is much 

 shorter, thicker, and reflected. Eanella ponderosa, Reeve, has near affinities in arrangement of 

 tubercles and teeth of outer lip, but is larger in form and quite different in colour and texture. 

 Eanella rana, Linne, has a much sharper apex, a much squatter form, and much more pointed tubercles. 

 Than Eanella livida, Reeve, the Challenger species is much shorter, thinner, more tubercled, its 

 suture is more impressed, and its pillar longer and straighter. Than Eanella subgranosa, Beck, it 

 is a much less compact form, the spire being higher and smaller, the base and suture much more 

 contracted ; the body-whorl is in all ways much smaller and shorter, but broader in proportion to 

 height.
