QQ GENUS BUCCINUM . 



66. BUCCINTJM MONILE, NOBIS. The Necklace Buccinum. 



(Collect. MASS.) MONTAGU, p. 243, pi. 8, fig. 1. 



Pi. XI, fig. 40. 



B. testa ovato-conica, laevi, nitida, albescente, fascia resell transversim 

 cincta ; anfractibus convexis, longitudinaliter tenuissime costatis ; sutura 

 ornatci tuberculis moniliformibus ; apertura ovata, alba, angustata ; labro 

 dextro intus striato ; columeM callosa. 



Shell ovate, conical, smooth, polished, whitish ; a decurrent 

 band of a rose color is seen beneath the suture, and three 

 others surround the middle of the lowest whirl ; that of the 

 middle is broader and more apparent. Spire composed of 

 seven slightly convex whirls, ornamented with longitudinal 

 ribs formed like folds, numerous and slightly elevated. The 

 upper edge of the whirls is a little flattened. The base of the 

 lowest is accompanied with two distinct ridges. The suture 

 is edged with rounded tubercles situated between each fold, 

 where they form a sort of necklace. Aperture ovate, white, 

 contracted above by a transverse fold of the callosity. Right 

 lip sub-truncated, somewhat denticulated upon the lower edge, 

 marked with transverse striae internally. Columella edge cov- 

 ered by a pretty thick callosity, spreading a little upon the 

 belly of the shell. 



Length 11 lines. Width 5i lines. 



Inhabits the coasts of England at Purbeck and at Wey- 

 mouth, and those of New Guinea. 



With some doubt, duoy and Gaimard gave this species as a 

 variety of the BUCCINUM coronatum, in their Voyage de I' Astro- 

 labe, p. 44, pi. 32, fig. 11-12. Indeed, it is very distinct from 

 this last, by its more elongated form, by the tubercles which 

 border the whirls of the spire, and by its longitudinal folds. 

 The specimen referred to by the authors we have quoted, was 

 covered with a ferruginous red tint. 



Dr. Pulteney found a specimen of this species at Purbeck, 

 upon the coasts of England. Montagu says, also, that it is 

 found at Weymouth, but rarely.
