48 MOLLUSCA FROM THE CRAG. 



the left lip by the reflected portions of the canal, like Buc. undatum ; there were 

 evidently longitudinal costse upon the shell, vestiges of which are remaining 

 upon some specimens on the upper volutions ; and traces of transverse striae may 

 occasionally be seen, but the shells are nearly smooth. It appears to be intermediate 

 in form between Strombus Norvegicus, Chemn., and Buc.fusiforme, Brod. (Zool. Jour., 

 1829, t. 3, f. 3), and it may be said somewhat to resemble F. Koninckii, Nyst (pi. 40, 

 f. 4), but that shell has a smaller and narrower canal, and a more acuminated apex. 

 Should this species hereafter prove to be the same as Woodward's shell, my name 

 must of course be given up.

Mam. Crag, Bridlington. Recent, North Seas and Massachusetts Bay. 



This species is not very abundant in the Red Crag. It appears to correspond 

 precisely with the shell brought from the North Seas, and it is identical with that 

 found in the beds of the Clyde. The young of this species appears to differ from 

 Murex Bamfius, Mont., in having a less number of reflected costas, as well as in its 

 projecting processes. I have not seen the form of the true Bamfius, from the Crag. 

 M. Loven has united the two species in his Synopsis, under the name of clathratum 

 {Murex clathratus, Linn.). Our specimens from the Crag have been more or less 

 rubbed, so that the transverse strise, if they ever possessed them, are no longer 

 visible. Among Mr. Bean's specimens from Bridlington, there is one with the name 

 of Bamfius attached to it, but it appears to me to be only the young of this species. 



The shell named Fusus scalariformis, figured by Nyst (pi. 40, fig. 5), is a different 

 species.
