TEREBRA.— Plate I. 



corrugato-arcuatis, transverse slriato-sulcalis, sulco 

 unico conspicuo pertuso infra suluras ; aperturd elon- 

 galo-ovatd, columella contracto-contortd. 



The clouded Terebra. Shell sharply turreted, orange- 

 red, largely tessellately clouded with white, whorls 

 longitudinally plicated, plaits obtuse, approximated, 

 corrugately arched, transversely striately grooved, with 

 a single conspicuous pricked groove below the suture, 

 aperture elongately ovate, columella contracted]}' 

 twisted.

 p. 25. 



Hub. Zanzibar, East Africa (in sandy mud, in deep water) ; 

 Thome. 



This species may be readily distinguished by its tessel- 

 lated clouding of milk-white upon a uniform orange-red 

 ground, which very little varies. 



Species 2. (Mus. Cuming.) 



Terebra consors. Ter. testa modice subulatd, albidd, 

 ftamnds fulvo-spadiciis talis pallide coloratd, aufracti- 

 bus subplanulalis, superne obsolete plicalo-crenulatis, 

 deinde sulco impresso cingulatis; aperturd breviusculd, 

 ad basin subcffusd, columella brevi, subrectd. 



The consort Terebra. Shell moderately subulate, 

 white, faintly coloured with broad fulvous-drab flames, 

 whorls rather flattened, obsoletely plicately crenulated 

 round the upper part, then encircled by an impressed 

 groove ; aperture rather short, a little effused at the 

 base, columella short, nearly straight.

 Terebra virginea, Deshayes. 

 Terebra glabra, Deshayes. 



Hub. Tahiti, Society Islands. 



M. Deshayes' T. virginea and glabra, described from 

 single specimens in the Cumingian collection, are worn, 

 discoloured T. consors. Thei - e are traces in both of the 

 plicated crenules and of the fulvous-dark spots of T. 

 consors, neither of which indications of character are de- 

 picted in the figures of the ' .Journal de Conchyliologie.' 



Species 3. (Eig. 3 a and 3 b, Mus. Cuming.) 



Terebra duplicata. Ter. testa acute subulatd, fulvo- 

 grised, nunc pallida, nunc caslaneo linctd, fascia an- 

 gustd albidd cinctd, maculis purpureis supra fasciam 

 vittatd, anfraclibus planatis, supra sulco conspicuo di- 

 visis, longitudinaliter acute sidcatis, plicis intermediis 



confertis et planatis; aperturd subanguste oblongd, 

 columella crasse contortd. 



The duplicate Terebra. Shell sharply subulate, 

 fulvous-grey, sometimes pale, sometimes chestnut- 

 stained, encircled with a narrow white band, filleted 

 over the band with purple spots, whorls flattened, lon- 

 gitudinally sharply grooved, the intermediate plaits 

 close set and flattened, whorls flattened, divided 

 round the upper part by a conspicuous groove ; aper- 

 ture rather narrowly oblong, columella thickly twisted.

 Terebra Lamarckii, Kiener. 

 Terebra Reevei, Deshayes. 



Hub. Zanzibar, China, Moluccas, Madagascar, etc. 



Of this species there are many varieties, according to 

 the extent and peculiarity of its geographical range ; and, 

 as in many other species of the genus, the shell is not 

 always composed of the same number of whorls. It varies 

 also in being stouter or more acicular, according to circum- 

 stances. T. Lamarckii is the spotted variety represented 

 at Fig. 3 b ; and T. Reevei is a delicate transparent co- 

 lourless variety from the Moluccas. 



Species 4. (Mus. Cuming.) 



Terebra maculata. Ter. testa obeso-subtdald, solidd, 

 ponderosd,fulvesrente, spadiceo fasciatim tiuctd, maculis 

 jiurpi'.reo-fuscis subiacleis bifasciald, quorum snperio- 

 ribus majoribus, anfraclibus planatis, lavibus, nitenti- 

 bus, primis ad dimidium inferiorem oblique crebricos- 

 tutis ; aperturd oblongd, columella parum contortd. 



The spotted Terebra. Shell stoutly subulate, solid, 

 heavy, yellowish, stained in a banded manner with 

 fawn-colour, encircled with two bands of milky pur- 

 ple-brown spots, of which the upper are the larger, 

 whorls flattened, smooth, shining, the first obliquely 

 closely ribbed on the lower half; aperture oblong, 

 columella but little twisted.

 Terebra maculata, Lamarck. 

 Subula maculata, Blainville. 



Hub. Society Islands, Molucca, and Philippine Islands. 

 Port Essington, Australia, etc. 



This well-known species, the largest of the genus, is 

 also one of considerable geographical range, but has little 

 variation withal. In the earlier whorls the lower half of 

 the whorl is closely oblicpiely ribbed, and the second row 

 of painting shows only in fine dots.
