1884.] ' LIGHTNING ' AND ' PORCUPINE ' EXPEDITIONS. 133 



' Talisman ' Expedition resemble S. torulosa of Brocchi ; and tlie 

 present species may be a slightly altered descendant of the latter 

 species. S. lanceolata, which is also a Subapennine fossil, seems to 

 deserve more especially the name or epithet longissima.

Distribution. Cap Breton (de Folin), Bay of Biscay (' Travail- 

 leu r ' Exp. 1882), Palermo (Mont.erosato) ; 97|-340 fms. 



Fossil. Pliocene : Central and Southern Italy. 



I am indebted to the kind generosity of my friend the Marquis 

 de Folin for an exquisite and quite perfect specimen of this lovely 

 shell. It is nearly an inch long and contains the operculum. It 

 has 1/ whorls, the 4 topmost of which are smooth and polished and 

 form a short pointed cone. The colour is reddish-brown, with a 

 white and thick outer lip ; there is no peristome, in consequence of 

 the inner lip being incomplete and scarcely discernible. Some of 

 the ribs in recent or living as well as in fossil specimens are occa- 

 sionally varicose or unusually thickened. 



The Marquis de Folin most obligingly proposed to give my name 

 to the species, not being aware that it had been already described. 



4. Scalaria vittata 1 , Jeffreys. (Plate X. fig. 4.) 



Shell slender, rather thin, semitransparent, not glossy : sculjj- 

 ture, about 15 sharp and curved, but not much raised longitudinal 

 ribs, each being crowned or surmounted just below the suture with 

 a short spine ; the interstices of the ribs are closely striated spirally, 

 and decussated by more than twice as many microscopic longitudinal 

 striee ; the first 3 or 4 whorls are smooth and polished : colour pale 

 yellowish-brown, with three spiral bands of a much deeper hue on 

 the last whorl and two on each of the succeeding whorls except 

 those at the top ; the bauds on the last whorl are equidistant, 

 one below the suture, the middle one round the periphery, and 

 the third (which is the broadest) encircling the base : spire 

 gradually tapering ; apex finely pointed : whorls 12-14, moderately 

 convex : suture dee]) : mouth roundish-oval, angular at the inner 

 base: outer lip strengthened by the last rib, and slightly expanded : 

 inner Up reflected on the pillar, and continuous with the outer lip. 

 L. 0-5. B. 015.
