TEREBRA.— Plate XXII. 



natis, varicoso-costatis, superne pertusis, interstitiis ob- 

 solete lineari-sulcatis ; aperturd minima, oblique con- 

 tracts, columella laminatd, contorto-recurvd. 



The shining Terebra. Shell rather stoutly acicular, 

 somewhat cylindrical, transparent-white, livid, whorls 

 slopingly flattened, varicosely ribbed, pricked round 

 the upper part, interstices obsoletely linearly grooved ; 

 aperture very small, obliquely contracted, columella 

 laminated, twistedly recurved. 



Hinds, Pro. Zool. Soc. 1843, p. 152. 

 Terebra plicatella, Deshayes. 



Hub. Marquesas (in sandy mud, at seven fathoms) ; Hinds. 

 Tasmania. 

 An extremely delicate, transparent, livid-white shell, 



with a small obliquely contracted aperture. The whorls 



are divided round the upper part simply by a row of 



punctures. 



Species 116. (Mus. Taylor.) 



Terebra livida. Ter. testa acuminato-subulatd, livido- 

 purpurascente aut plumbed, anfractibus declivi-plana- 

 tis, sideo superne divisis, dense plicato-costatis, costis 

 plano-angulatis, interstitiis striato-sulcatis ; aperturd 

 oblongo-ovatd, intus castaned, columella contorto-re- 

 curvd, carinatd. 



The livid Terebra. Shell acuminately subulate, livid- 

 purple or lead-colour, whorls slopingly flattened, 

 divided by a groove round the upper part, closely 

 plicately ribbed, ribs flatly angled, interstices striately 

 grooved ; aperture oblong-ovate, chestnut in the in- 

 terior, columella twistedly recurved, keeled. 



Hab. Philippine Islands ; Cuming. 



A well marked species, of which specimens have been 

 confounded in Mr. Cuming's collection with M. Quoy's 

 /'. cancellata. It is of a different form, more flatly and 

 straightly sculptured, less corded at the sutural margin, 

 and of a peculiar livid lead-colour. 



Species 117- (Mus. Cuming.) 

 Terebra blanda. Ter. testa subulalo-turritd, ad 



ai/gulato-fusiformi, pellucido-albd, ad marginem sutu- 

 ralem opacd, aurantio-rufo maculatd, apice purpuras- 

 cente, anfractibus declivi-convexis, tenue conceutrice 

 plicatis, superne sulco divisis, margine tumido; aper- 

 turd. oblongd, subangustd, columella ud basin productd 

 et recurvd. 

 The charming Terebra. Shell subulately turreted, 

 angularly fusiform at the base, transparent-white, 

 opaque, spotted with orange-red at the sutural mar- 

 gin, purple at the apex, whorls slopingly convex, 



finely concentrically plicated, divided at the upper 

 part by a groove, margin swollen ; aperture oblong, 

 rather narrow, columella produced and recurved at 

 the base. 



Deshayes, Pro. Zool. Soc. 1859, p. 298. 



Hab. Japan. 



Very distinct from any other species of Terebra, and 

 more than usually produced in a fusiform manner at the 

 base. 



Species 118. (Mus. Cuming.) 



Terebra Swainsoni. Ter. testa obeso-aciculari, subcy- 

 Undraced, rosaceo-carneo suffusd, anfractibus convexis, 

 subangustis, lougitudiualiter plicato-costatis, superne 

 pertusis, interstitiis obscure lineari-sulcatis ; aperturd 

 minima, oblique contractu, columella laminatd, cari- 

 natd, contorto-recurvd. 



Swainson's Terebra. Shell stoutly acicular, some- 

 what cylindrical, suffused with pinkish flesh-colour, 

 whorls convex, rather narrow, longitudinally plicately 

 ribbed, pricked round the upper part, interstices 

 obscurely linearly grooved ; aperture very small, ob- 

 liquely contracted, columella laminated, keeled, twist- 

 edly recurved. 



Deshayes, Pro. Zool. Soc. 1859, p. 299. 



Hab. Sandwich Islands ; Pease. 



Of a characteristic cylindrical form, with a remarkably 

 small obliquely contracted aperture, the shell being suf- 

 fused throughout with a delicate blush-colour. 



Species 119. (Mus. Taylor.) 



Terebra brevicula. Ter. testa abbreviato-subulatd 

 olivaceo-pl umbed , purpurea vitlald, medio albifasciatd . 

 anfractibus declivi-convexis, iuferue subangulatis, ml 

 angulum plicato-tuberculatis, tuberculis distantibus, 

 margine sulurali tumido, vix creuato ; aperturd ovato- 

 effusd, columella carinatd et contorto-recurvd. 



The short Terebra. Shell shortly subulate, olive 

 lead-colour, filleted with purple-white, banded in the 

 middle, whorls slopingly convex, somewhat angled 

 at the lower part, plicately tubercled on the angle, 

 tubercles distant, sutural margin swollen, scarcely 

 crenated ; aperture ovately effused, columella keeled 

 and twistedly recurved. 



Deshayes, Pro. Zool. Soc. 1852, p. 296. 



Hab. Tasmania. 



A very distinct typical form, in which the encircling 



groove is replaced by a broad concave depression, the 



sculpture below it having the appearance of tubercles.
