TER E Triphora gemmegens, n. sp. PI. xxiii., figs. 7 and 8. SHE 
Shell sinistral, solid, of 12 whorls. Protoconch of three 
whorls, slightly deviated from the axis, swollen convex, 
ending abruptly, with three carine and obsolete axial lire. 
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 lire, which cross the inter- 
spaces, and the sutural spaces. 
Dim.—Length, 71 mm.; breadth, 1°8 mm. 
Locality.—Type in 40 fathoms off Beachport, with 2 
others.

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 7. angasi, Crosse and 
Fischer, in its short, stout pupxform 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 7. 
angasi, and might be classed as a pup«form variety of the 
latter, or a spiculate variety of 7. labiata. °
