punctatis transversis insculptd ; columelld quinqueplicatd : long. 

 2^, lat. XT poll. 



Hab. ad Insulam Annaan. 



Found on the reefs. 



Minute longitudinal lines cross the transverse thick- set punctated 

 ones, and with the punctures produce a somewhat cancellated ap- 

 pearance, which may be also detected by the touch. 



The base of the columella is strongly developed, milk white, and 

 shining, reminding the observer of the same part in Ancillaria. 



On the paper, " Type 5, 3."

 Found on the reefs. 



Mr. Swainson has %vritten on the paper containing it, " Type 4, 

 4. This is one of the most extraordinary shells in the collection, as 

 it so closely resembles the Mitra Terebralis that, but for its possess- 

 ing the generic characters of Tiara, it might pass for the same 

 species." 



It is one of the most slender of its genus, and has very much of 

 the general character and form of a Terebra ; and its resemblance to 

 Terebra is increased by the circumstance of its having one spiral 

 groove, more deeply impressed than the others, placed at about one 

 third of the length of each volution before the suture. The points 

 of contact of the decussating with the longitudinal grooves are deeply 

 impressed. 



There is a fine specimen in Mr. Broderip's collection. 



Mr. Sowerby has furnished me with the account of this species.
