Specific Char(ictevs.—^\\e\\ small, elongate, ovato-conical, thin ; whorls 8 — 9, flat 

 or nearly so, the last one-third the total length, ornamented by inconspicuons ribs, 

 interrupted by the suture, with one or more spiral rows of punctures in the inter- 

 spaces, placed near the centre of each whorl ; suture distinct, channelled ; spire 

 slender, subcylindrical, regularly but gradually diminishing in size towards a blunt 

 and rounded apex ; inouth small, ovate, angulate above. 



Dimensions. — L. 6 mm. B. 2 mm. 



Distrihution. — Becent : Mediterranean (rare), Sicily, Algeria to Tunis, Morocco. 

 fossil : Coralline Crag : Boyton. 



Ii e ma i-ks. — The interesting specimen figured under this name is from the 

 Coralline Crag of Boyton. It is new to our deposits, but seems to correspond with 

 a rare Mediterranean form originally described by the Marchese di Monterosato as 

 equivalent to our T. internodula, to the type of which, however, it bears but little 

 real resemblance. Subsequently it was considered specifically distinct by the latter 

 authority and called T. rosea, in which he has been followed by Kobelt and some 

 others. It may be distinguished by its sculpture, which shows one or two trans- 

 verse rows of intercostate punctures placed nearly in the centre of the whorls. 



Our fossil has been submitted to M. Dantzenberg, who confirms my reference of 

 it to T. (PyrgoUdinm) rosea.
