flange projects round the edge of the mouth, attached as a shelf 

 across the body ; it projects minutely down the pillar, but leaves 

 no chink behind it.— L. 0-2. B. 0-ok 



From 50 fms., Funchal Bay. 



This species has so much character, that though I found only 

 one possibly young and not quite perfect specimen, I do not think 

 it will ever be difficult to recognize. It is more like S. tortilis, 

 Wats., ' Challenger ' Graster. p. 139, is. 1, than any other I know ; 

 but that species has a shallower and less oblique suture with 

 flatter-sided whorls, and the whole sculpture, but especially 

 the basal keel, is totally diff'erent. S. funiculata, Wats. {I. c. 

 p. 141, ix. 4), is still more divergent. It is certainly not the 

 S. crenulata, Linn., of the Canaries, nor the aS'. Sotessieriana, 

 d'Orb., of Cuba. It belongs to the very marked and curious 

 group which, besides those referred to here, includes the S. longis- 

 sima, Seguenza, the S. torulosa, Broc, and several others given 

 by Sacco from the Italian tertiaries, and by Deshayes from the 

 Paris basin. 



19. SCALAEIA. FiSCHEUI, n. Sp. 



Shell small, delicate, translucent, with short, rounded, de- 

 pressed whorls, a scalar spire whose whorls are each rather 

 more contracted at the bottom than at the top, fine close- 

 set spurred ribs and very distinct spirals, a strongly impressed, 

 not very oblique suture, and a small base. Sculpture — Longitu- 

 dinals : 23 or 24 thin projecting riblets, which crowd the surface, 

 and from each, of which close to the suture rises a small tooth, 

 often broken ofE. Spirals : of these some 17 to 20 can be counted 

 on the 2nd last whorl just above the corner of the mouth ; they 

 are rounded, well raised, can be traced as they cross the riblets, 

 and are, like the whole surface of the shell, fretted with minute 

 longitudinal scratches. Colour translucent white. Spire high 

 and narrow. Whorls 7, exclusive of the embryonic tip ; they 

 are short, with a rounded profile, but lie like somewhat oblique 

 slabs from the depth and straightness of the suture and the ex- 

 pansion of each whorl below the suture in consequence of the 

 minute projection there of the tooth which crowns each rib. 

 Suture deep, strongly marked by the flat shelf below it on the 

 top of the succeeding whorl ; it runs somewhat obliquely but in 

 a very straight line across the shell. Apex has a peculiar almost 

 metallic sheen, is a very perfect, rather high, fine-pointed cone,
