TEREBRA.— Plate XIII. 



two. It is described from a single specimen in Mr. 

 Cuming's collection which seems to pass through a state, 

 well illustrated by another single specimen in the Cumin- 

 gian collection, into T. Dussumieri. 



Species 56. (Mus. Cuming.) 



Terebra Bernardii. Ter. testa subulatd , griseo-plumbed, 

 obscure albifasciatd, anfractibus convexis, subvenlri- 

 cosis, tenue plicato-cosiatis, costis valde coarctatis, su- 

 perne late impressis ,■ aperturd ovatd, fauce castaned, 

 columella obesd, brevi, castaned. 



Bernardi's Terebra. Shell subulate, greyish lead-colour, 

 obscurely white-banded, whorls convex, slightly ven- 

 tricose, thinly plicately ribbed, ribs very crowded, 

 broadly impressed round the upper part ; aperture 

 ovate, interior chestnut, columella rather stout, short, 

 chestnut. 



Deshayes, Journ. de Conch. 1857. 



Hab. Moreton Bay, east coast of Australia. 



This shell belongs to the same type as T. duplicata, and 



is very closely allied to that species. Its most promi- 

 nent characteristic is the delicate ventricose form of the 

 whorls. 



Species 57. (Mus. Cuming.) 



Terebra tricolor. Ter. testa yracili-lxi.rri.td , aurantio- 

 spadiced, interdum albo-marginatd , lineis tribus rufis 

 distantibvs cingulatd, anfractibus plano-convexis, pri- 

 mis subcrenulatis, ceeteris Itevibus ; aperturd pared, 

 columella, contorto-recurvd. 



The tricoloured Terebra. Shell slenderly turreted, 

 orange-fawn, sometimes edged with white, encircled 

 with three distant red lines, whorls flatly convex, the 

 first slightly crenulated, the rest smooth ; aperture 

 small, columella twistedly recurved. 



Sowerby, Tankerville Cat. App. p. 24. 

 Terebra teeniolata, Quoy. 



Hab. Tongataboo, Friendly Islands. 



This species, which is very characteristic in its typical 

 state, encircled with three distant orange-red lines, differs 

 very little from some varieties of T. cingulifera.
