 minata, solidd, varie purpureo fasciatd, anfractibus 

 declivi-convexis, subungualis, superne concavo-divisis,

The varicose Terebra. Shell conieally subulate, acu- 

 minated, solid, variously purple-banded, whorls slop- 

 ingly convex, rather narrow, concavely divided round 

 the upper part, varicosely ribbed, ribs oblique, con- 

 centric, rather distant, interstices striately grooved ;

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



Hah. Gulf of Papagayo, west coast of Central America (in 

 mud, at twenty-three fathoms) ; Hinds. 



The -ribs of this species have a peculiar obliquely con- 

 centric character, and do not appear in the form of cre- 

 uules on the sutural margin, which is depressly exca- 

 vated. 



Species 121. (Fig. b, Mus. Taylor; Fig. a, 

 c, d, e,f, Mus. Cuming.) 



Terebra aciculina. Ter. testa aciculari-subulatd, ad 

 basin veutricoso-effusd. spadiceo-albd vel cinered, ui- 

 tente, versusbasin pallide fasciatd, suturis a/bis. deinde 

 pane lis fuse is elongatis ciuctd, anfractibus declivi-pla- 

 natis, indicisis, superne plus minus elongate plicatia ; 

 aperturd brevi, ad basin late effusd, columella brevis- 

 simd, callosd, recta, ad basin carinatd. 



The needle-like Terebra. Shell acicularly subulate, 

 ventricosely effused at the base, fawn-white or ash- 

 colour, shining, pale-banded towards the base, su- 

 tures white, then encircled with elongated brown dots, 

 whorls slopiugly flattened, undivided, more or less 

 elongately plicated round the upper part ; aperture 

 short, broadly effused at the base, columella very 

 short, callous, straight, keeled at the base.

 Terebra anomala, Gray. 

 Terebra cinerea, Basterot (not of Born). 

 Terebra inconstant, Hinds. 

 Terebra Matheroniana, Deshayes. 



Hab. Manilla, Singapore, Sandwich Islands. 



This species varies little in form, except in having 

 the plicated sculpture more or less strongly developed. 

 In colour it is more variable, and has been described three 

 times over. The shells represented at Fig. 121 d and 

 121/, ash and ash-grey, and comparatively smooth, pass- 

 ing into T. nimbosa, have been mistaken for Bora's Bicc- 

 ciiiHui ciuereum; those at Fig. 121 a and 121 c, equally 

 smooth, but of a fawn-white or fulvous-drab, are Dr. 

 Gray's T. anomala ; and those at Fig. 121 b and 121 e, 

 states of the species in both colours, with the plicated 

 sculpture stronger, are Mr. Hinds's T. inconstant. 



Species 122. (Mus. Cuming.) 



Terebra continua. Ter. testa acuminato-oblonyd, sub- 

 pyramidali, /acted, carneold, adbasin pallide fasciatd, 

 anfractibus declivi-planatis, indi visis, Icmgitudinaliter 

 tenuiplicatis, hevigatis ; aperturd parvd, subangustd, 

 columella arcuatd, brevi. 



The continuous Terebra. Shell acuminately oblong 

 somewhat pyramidal, cream-coloured, flesh-tinted, 

 faintly banded at the base, whorls slopingly flattened, 

 undivided, longitudinally thinly plicated, smooth ; 

 aperture small, rather narrow, columella arched, 

 short. 



Deshayes, Pro. Zool. Soc. 1859, p. 286. 



Hab. Japan ? 



A flesh-tinted cream-coloured shell, of a straight pyra- 

 midal form, veined throughout with thin plications. 



Species 123. (Mus. Cuming.) 



Terebra solida. Ter. testa cylindraceo-oblongd, i 

 obesuld, spadiceo-lacted, maculis quadratis opac 

 tessellato-encausticd, anfractibus plano-convexis, indi- 

 visis, l/evihus ; aperturd parvd, oblong a, cola 



i-i ctd, brevi, ad basin carinatd. 



Tin; solid Terebra. Shell cylindrically oblong, 



rather stout, fawn cream-colour, tessellately enamelled 

 throughout with square opaque white blotches, whorls 

 flatly convex, undivided, smooth ; aperture small, ob-
