66. BUCCINUM MONILRE, Nosis. The Necklace Buccinum. 
(Collect. Mass.) Mownraeu, p. 243, pl. 8, fig. 1. 
Pl. XI, fie. 40. 
B. testa ovato-conica, levi, nitidi, albescente, fascia rosea transversim 
 eincta; anfractibus convexis, longitudinaliter tenuissime costatis ; suturd 
ornata tuberculis moniliformibus; apertura ovata, alba, angustata ; labro 
dextro intus striato; columella 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 strie internally. Columella edge cov- 
ered by a pretty thick callosity, spreading a little upon the 
belly of the shell. : 
Length 11 lines. Width 52 lines. 
Inhabits the coasts of England at Purbeck and at Wey- 
mouth, and those of New Guinea. 
With some doubt, Quoy and Gaimard gaye this species as a 
variety of the Buccinum coronatum, in their Voyage de [ Astro- 
labe, p. 44, pl. 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.
