Traill's Terebra. Shell acicularly subulate, orange- 

 yellow, encircled with a narrow violet band, broadly 

 banded at the base, whorls slopingly flattened, elou-

Very like the preceding species, but smaller and dif- 

 ferently coloured, with a distinct keel at the base of the 

 columella. 



Species 143. (Mus. Cuming.)

 culd, livido-pnrpurascente, plumbeo iinctd, infra sutu- 

 ras saturate maculatd, ad basin latifascv to, anfracti-

 aperturd parvd, columella appresse arcuatd, brevi. 



The acuminated Terebra. Shell acicularly subulate, 

 rather thin, livid-purple, tinged with lead-colour, 

 dark-spotted beneath the sutures, broadly banded at

Bullia acuminata, Gray, MS. in Mus. Brit. 



Hab. ? 



Of the same type as the two preceding species. The 

 ground colour of the shell is a sombre leaden-purplish hue, 

 with a row of dark spots beneath the suture, in the place 

 of the band. 



Species 144. (Mus. Cuming.) 



Terebra Nassoides. Ter. testa obeso-subulaid, Icevigata, 

 roseo-cinered, albo-marginatd, plumbeo-fasciatd, an- 

 fractibus declivi-convexis, indivisis, varicoso-costatis, 

 spiraliter minute striatis ; aperturd parvd, columella 

 brevi, carinatd et paululum recurvd. 



The Nassa-like Terebra. Shell stoutly subulate, 

 smooth, pinkish-ash, white-edged, banded with lead- 

 colour, whorls slopingly convex, undivided, varicosely 



ribbed, spirally minutely striated ; aperture small, 

 columella short, keeled and a little recurved. 



Hinds, Pro. Zool. Soc. 1843, p. 158. 



Hab. Red Sea ; Lord Mountnorris. 



A rather stout, varicosely ribbed species, of a pinkish- 

 ash colour, white at the sutural margin, thin, encircled 

 with a narrow band of dull lead-colour, and also at the 

 base. 



Species 145. (Mus. Cuming.) 



Terebra fictilis. Ter. testa obeso-subulatd, acumii a a, 

 albidd, inferne violaceo-caruleo cingulatd, anfractibus 

 declivi-convexis, sulco impresso superne divisis, longi- 

 tudinaliter plicato-costatis ; aperturd ovata, columella 

 brevi, subcontortd. 



The earthen Terebra. Shell stoutly subulate, acu- 

 minated, whitish, encircled at the lower part with 

 violet-blue, whorls slopingly convex, divided at the 

 upper part by an impressed groove, longitudinally 

 plicately ribbed ; aperture ovate, columella short, a 

 little twisted. 



Hinds, Thesaurus Conch, p. 183. pi. 45. f. 109, 110. 



Hab. Australia. 



The colouring of this species is characteristic ; the upper 

 half of the whorls is white, the lower half is violet-blue, 

 and a portion of the violet-blue is left exposed in each 

 whorl at the suture. 



Species 146. (Mus. Cuming.) 



Terebra polygyrata. Ter. testa gracili-turritd, subpy- 

 ramidali, fulvo-aurantid, albo-marginatd, anfractibus 

 angustis, rotuudalis, superne sulco pertuso divisis,

 aperturd minima, columella constrictd et contortd. 

 The many-whorled Terebra. Shell slenderly turreted, 

 subpyramidal, fulvous-orange, edged with white, 

 whorls narrow, rounded, divided at the upper part by 

 a pricked groove, concentrically closely ribbed, inter- 

 stices linearly grooved; aperture very small, columella 

 constricted and twisted. 

 Deshayes, Pro. Zool. Soc. 1S59, p. 301.

An elegantly convoluted species, in which the whorls 

 are numerous and rounded, and their upper and lower
