90. BUCCINUM MARGINULATUM, LAM. The Margined 



Buccinum. 



(Collect. MASS. LAM.) GUALTIERI, pi. 44, fig. n. 

 Pi. XXIX, fig. 117. 



B. testa ovato-acuta, plicis tenuibus longitudinalibus confertis striisque 

 transversis decussata, subgranulosa, colore varia ; anfractuum margine 

 superiore crassiusculo, crenulato ; spira exsertiuscula ; labro inttis striato. 



Shell ovate, slightly ventricose ; spire pointed, formed of 

 six or seven whirls, rounded upon their upper part, separated 

 by a pretty deep and slightly canaliculated suture. The whole 

 surface is very regularly chequered by approximate, longitu- 

 dinal striae, and by other transverse striae, not less regular than 

 the first. Aperture white, callous, sub-rounded. Right lip 

 thick, striated internally ; columella covered by a wide, rather 

 thick callosity, ornamented lengthwise with small, irregular 

 wrinkles. The coloring of this shell is grayish, or of a pale, 

 uniform fawn-color, presenting upon the whirls one or several 

 transverse brown or whitish bands. 



Length 8 lines. Width 5 lines. 



Inhabits the Mediterranean, the coasts of Naples, of Bar- 

 bary, and the Seas of Sun da. 



Young specimens of this shell were brought from the last 

 locality by Bell anger, who has given a figure of it, in his 

 account of his voyage to the East Indies, pi. 3, fig. 6 et 7. 

 Deshayes has given it the name of BUCCINUM conoidale. See 

 also our pi. 27, fig. 109. This shell differs from the adult only 

 in the right lip which is thinner, and in the callosity, which is 

 less prominent.
