TURBO. 195 



I am inclined to believe that T. sparverius is a variety of T. a-as- 

 SKS. Both are separated from T. setosus and its allies by the ol)so- 

 lesceuee of the spiral lirpe 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, 

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

 sjjaces, frequently Avith interstitial lirulie ; 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; Pownotus 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. granosus Phil, is prol)al)ly this species. It cannot be positively 

 determined. 



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



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

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



T. JOBiENsrs Tapparone-Canefri, 1878. Unfigured. 



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

 6, with irregular incremental stria?, spirally lirate, the lir?e unequal ; 

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

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

 ulose ; base with larger and irregular lira? ; aperture round, smooth, 

 silvery within ; peristome crenulated, subangulate above, narrowly

 gined without with reddish orange, effliseatbase ; color rufous- whitish

Alt. o8. diam. 46 mill. 



Ins. Jobi, Bay of Geelvmk, 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 mar2:ins.
