TEREBRA 



Plate VI. 



Species 19. (Fig. a, b, Mus. Cuming.) 



Terebra corrugata. Ter. testa elongato-turritd, per- 

 angustd, fulvo-lacted, maculis purpureis triseriatim 

 picfd, anfractibus convexo-planatis, superne tumidim- 

 culis ft nodoso-crenulatis, crenulis sulco divisis ; colu- 

 mella valide contorto-recurvd. 



The wrinkled Terebra. Shell elongately turreted, 

 very narrow, fulvous cream-colour, painted with three 

 rows of purple spots, whorls convexly flattened, rather 

 swollen, and nodosely crenulated round the upper 

 part, the crenules divided by a groove ; columella 

 strongly twistedly recurved. 



Lamarck, Anim. sans vert. vol. x. p. 244. 

 Terebra punctata, Gray. 

 Terebra regina, Deshayes. 

 Terebra bitorquata, Deshayes. 



Ilab. Loanda, west coast of Guinea (found on the sands) ; 

 Dr. Tarns. 



M. Deshayes's T. regina, of which the original type is 

 represented at Fig. 19 b, is a smooth, obese variety of 

 Lamarck's T. corrugata ; and his T. bitorquata, of which 

 the original type, belonging to M. Crosse, of Paris, has 

 reached me too late to be figured, is a fine symmetrical 

 example of the noduled variety, of smaller dimensions, 

 from Mr. Cuming's collection, represented at Fig. 19 a. 

 I agree with M. Kiener in considering these to be varie- 

 ties. The uppermost row of purple spots appears in the 

 interstices between the nodules ; and the nodules, divided 

 by a spiral impressed line, are in the lower row frequently 

 more or less obsolete. M. Crosse's very elegaut specimen 

 is at least an inch longer than the Cumingian specimen. 

 In both the columella is unnaturally exposed to view from 

 the lip being broken away. 



Species 20. (Mus. Cuming.) 



Terebra pertusa. Ter. testa anguste subulatd, auran- 

 tio-succined, albo interdum tessellatd, prope suturam 

 rufo-purpureo dense strigato-maculatd, anfractibus pla- 

 no-couvexis, longitudinaliter tenue plicato-liratis, inter- 

 stitiis undique pertusis ; columella recta. 



The pricked Terebra. Shell narrowly subulate, orange- 

 amber, sometimes tessellated with white, closely 

 streak-spotted with reddish-purple next the suture, 

 whorls flatly convex, longitudinally finely plicately 



ridged, the interstices pricked throughout ; columella 



straight. 

 Buccinum pertusum, Born, Mus. p. 267. pi. 10. f. 13. 

 Hab. Darnley Island, Australia; Jukes. 



Of a delicate orange-amber colour, painted next the su- 

 ture in a very characteristic manner in the interstices be- 

 tween the folds with reddish-purple. Though figured 

 nearly a century ago by Bora in his ' Vienna Museum,' 

 the species was not known to Lamarck, and it is only very 

 recently that its habitat has been discovered. 



Species 21. (Mus. Cuming.) 



Terebra Argus. Ter. testa subelongato-sululatd, albes- 

 cente, maculis subquadratis pallidissime spadiceis tri- 

 seriatim, in anfractit ultimo quadriseriatim, cinctd, an- 

 fractibus planulatis, superne tumidmsculis, primis ad 

 margiuem tenue crenulatis et sulco divisis ; columella 

 subrectd. 



The Argus Terebra. Shell somewhat elongately subu- 

 late, whitish, encircled with three rows, in the last 

 whorl with four rows, of somewhat square, very pale, 

 fawn spots, whorls flattened, rather swollen round 

 the upper part, the first, whorls finely crenulated at 

 the margin, and divided by a groove ; columella 

 rather straight. 



Hinds, Pro. Zool. Soc. 1843, p. 160. 



Terebra nebulosa, Kiener (not of Sowerby). 



Hab. Tahiti, Society Islands (in coral sand, on the reefs) ; 

 Cuming. Nukuhiva, Marquesas Islands ; Hinds. 

 The spots are peculiarly faintly stained, and very regular 



and characteristic. 



Species 22. (Mus. Cuming.) 



Terebra subulata. Ter. testa elongate subulatd, ful- 

 vesceute-albd, maculis purpureo-fitscis subquadratis bi- 

 seriatini, in anfractu ultimo triseriatim, cinctd, an- 

 fractibus couvexo-planalis, superne tumidiuscnlis, pri- 

 mis perpaucis tcnuierenulatis, sulco divisis; columella 

 brevi, subcontortd. 



The subulate Terebra. Shell elongately subulate, 

 fulvous-white, encircled with two rows, in the last 

 whorl with three rows of somewhat square purple- 

 brown spots, whorls convexly flattened, rather swollen 

 towards the upper part, the first few finely crenulated
