TURBO. 195 



I am inclined to believe that T. sparverius is a variety of T. cr<i- 

 6U8. Both are separated from T. setosus and its allies by the obso- 

 lescence of the spiral line around the axis. 



T. SETOSUS Gmel., 1788. PI. 63, fig. 32. 



Shell solid, ovate-pointed, imperforate, whitish, or greenish, macu- 

 lated with brown and olive ; spire conic, acute ; whorls 6, convex, 

 striute and spirally lirate, the ridges unequal, wider than the inter- 

 spaces, frequently with interstitial lirula? ; aperture large, oval, white 

 within ; outer lip frequently green-tinged, fluted ; columella arcuate, 

 deflexed and dilated at base. Alt. 70-80, diam. 60-70 mill. 



South-western Pacific; Poumotus Is., N. Caledonia; Marquesas; 

 Kingsmill Is., Seychelles] Isle of France. 



Operculum circular, flat or slightly concave within, with four 

 whorls and subcentral apex ; outside convex, brown, coarsely gran- 

 ulose in the middle, paler and more finely granular at margins. 



T. granosm Phil, is probably this species. It cannot be positively 

 determined. 



Var. PATULUS Phil. PL 63, fig. 33. 



Shell shorter, thicker with larger mouth, shorter spire and canal- 

 iculate sutures. Alt. 84, diam. 75 mill. 



T. JOBIENSIS Tapparone-Canefri, 1878. Unfigured. 



Shell ovate-conic, narrowly umbilicate, solid ; spire acute; whorls 

 6, with irregular incremental stride, spirally lirate, the lirse unequal ; 

 last whorl carinate above, planulate between carina and suture, in- 

 flated around the middle ; revolving lirse fine, close, minutely gran- 

 ulose ; base with larger and irregular lir&3 ; aperture round, smooth, 

 silvery within ; peristome crenulated, subangulate above, narrowly 

 margined with lemon yellow and orange ; columella arcuate, mar- 

 gined without with reddish orange, effuse at base ; color rufous- whitish 

 with vivid wide irregular reddish-chestnut maculations. 



Alt, 58. diam. 46 mill. 



Ins. Jobi, Bay of Geelvink, N. Guinea. 



Operculum flat within, castaneous, with 4 whorls and nucleus 

 one-third the distance across the face ; outside very convex, polished 

 and greeenish at centre, minutely granulose and variegated with 

 brown and white at margins.
