PLATE 2, 3, 4. 
FIG. 9. 
HELMINTHOLITHUS Entrochites (prominens) 
stipite articulis aequalibus : ambitlbus rotundatis lasvi- 
bus, ramis alternis. S. p. 
Differs from the foregoing species^ in the ambits of the 
joints being somewhat prominent and rounded. The 
branches are alternate ; but I have not found them, in a 
sufficiently perfect state, to determine, whether they are 
jointed or not. 
Found with the above. 
FIG. 10. 
HELMINTHOLITHUS Entrochites (verrucosus) 
stipite articulis requalibus: ambitibus rotundatis tu- 
berculatis, ramis . S, p. 
Differs from the species last described, in having the 
ambits of the joints studded with a single row of tubercles 
or small wart-like bodies. The structure of the arms or 
branches uncertain. 
Not common. I have met with a few imperfect speci- 
mens about Buxton : that from which the figure is taken, 
was found near Bakewell. — Limestone.
