This is an elongated turreted shell, composed of six or seven convex 
spiral whorls, with rather deep sutures. The surface of the first five or six 
whorls is ornamented with six thin, nearly equidistant ribs parallel with the 
sutures, and separated by smooth, concave furrows broader than the ribs 
themselves. The last whorl is rather ventricose, and covered with fourteen 
or fifteen ribs, the upper ones being rather closer together than the six lower 
ones. The aperture is elongated and oval. 
Dimensions . — The length is fifteen, and the breadth ten, millimetres, 
and the spiral angle forty-six degrees. 
Delations and Differences. — Professor Phillips has figured a species of 
Macroclieilus to which he has given the name Baccinum (?) parallele (Geol. 
Yorkshire, PI. 16, Pig. 8) having a sj)iral angle nearly identical Avith that of 
this species ; its ornamentation is also similar, although the ribs are more 
numerous. The chief difference between them is that the lower part of the 
spiral Avhorls in Buccinum parallele has a flat surface, while the spiral whorls 
of M. Jilosus are regularly convex throughout. 
Horizon and Localities . — According to Morris this sjoecies is found at 
Booral. Mr. Clarke found several specimens in a blackish grey limestone on 
the Kama, in the Ichthyodorulite Kange, associated Avith a species of Palcearca.
