It differs from T. siibuhi in its unicarinate protoconch,. 

 and in having the 4 ribs throughout. 



Triphora spica, n. sp. PI. xxiii., lig. 1. 



Siiell solid, long, narrow, upper third elongate-conical,, 

 the rest nearly cylindrical. Protoconch of 5 whorls, con- 

 vex, with two central closely approximate spiral threads and 

 numerous axial bars. Spire-whorls 17, the first three with. 

 two nodulate spiral ribs, and an infra-sutural small, smooth 

 cord. In the fourth whorl this becomes nodulate ; and get- 

 ting thicker equals the other spirals in the sixth whorl. Be- 

 tween the twelfth and thirteenth whorls a supra-siitural thin 

 threadlet appears and gradiially enlarges and grows sub- 

 nodular. The nodules in a spiral row on the penultimate 

 are 17, transversely elliptical, and are joined spirally by a 

 bar about one-third of their width, and vertically by obso- 

 lete bars nearly their own width. The body-whorl has three- 

 spiral ribs, a subnodulated peripheral riblet, a dis- 

 tinct smooth, stout, basal spiral, and an obsolete one at 

 the base of the canal. The. lip is broken. Colour, light- 

 brown, with axial streaks of darker-brown from suture to 

 suture ; sometimes these happen to be continuous over two- 

 or more whorls, sometimes not ; the protoconch is of darker 

 brown. 



Dim. — Length, 97 mm. ; breadth, 1'55 mm. ; length of 

 protoconch, '55 mm. 



Locality. — Type, 40 fathoms off Beachport, with 4 

 others ; 55 fathoms off Cape Borda, 10 good, many poor ; 

 62 fathoms off Cape Borda, 1 poor ; Gulf St. Vincent, under 

 25 fathoms, 7 poor. The habitat would aj^pear to be in 40 

 to 50 fathoms. 



Diagnosis. — From T. Icesteveni, Hedley, it differs in its- 

 nodulated spirals and in its colour.
