Triphora gemmegens, n. sp. PI xxiii., ligs. 7 and 8. 



Shell sinistral, solid, of 12 whorls. Protoconch of three 

 whorls, slightly deviated from the axis, swollen convex, 

 ending abruptly, with three carinse and obsolete axial lirae. 

 Spire-whorls eight, subconvex, with three spiral ribs. Sutural 

 spaces well marked, with a distinct supra-sutural thread. 

 Base flatly convex, bordered by the supra-sutural lira, and 

 with two broad, low, smooth spirals. Aperture roundly rhom- 

 boidal, pinched at the suture into a sinus, broken in front ; 

 inner lip erect and thick along the straight columella, outer 

 lip ascending at the suture. Sculpture : the upper two spirals 

 are closer than the lower, sigmoid transversely, wider than 

 the interspaces, not gemmed (whence the name), but rough- 

 ened by irregular obsolete axial lirse, which cross the inter- 

 spaces, and the sutural spaces. 



Dim. — Length, 7'1 mm.; breadth, 1"8 mm. 



Locality. — Type in 40 fathoms off Beachport, with 2 

 others.

Triphora labiata, A. Adams, Hedley, Proc. Linn. Soc, New 

 South Wales, 1903 (1902), vol. xxviii.. p. 617, pi. xxxiii., figs. 42, 

 43, 44; Pritchard and Gatlifl. Proc Roy. Soc, Victoria, 1906, 

 vol. xviii. (N.S.), p. 60, "Western Port, Victoria." 



Dredged in 62 fathoms, north-west of Cape Border, 2 

 poor. Taken on the beach. Gulf St. Vincent, 2 good ; Venus 

 Bay, West Coast, 11 moderate; St. Francis Island, 11 poor. 



The species differs from the typical T. angasi, Crosse and 

 Fischer, in its short, stout pupseform figure and its mamil- 

 late apex. But a shell from the beach at Kingston and an- 

 other from the beach of Gulf St. Vincent have the same 

 shape, but a sharp, elongate protoconch like that of T. 

 angasi, and might be classed as a pupseform variety of the 

 latter, or a spiculate variety of T. labiata.
