SERPULA (VERMILIA ?) macropus. 
TAB. DXCVII. —fig. 6. 
Spec. Char. Tube thicks slightly curved, rapidly 
increasing, triquetrous ; aperture small, round, 
elevated by the thick mass that fixes the tube; 
front sulcated. 
The two free sides of this worm-shell are nearly flat ; 
they have, however, sometimes a slight angle along the 
middle of each : the thick mass that elevates the aperture 
from the substance it is placed upon is so divided in front 
as to resemble two clumsy feet. 
From the Norwich Chalk in the cabinet of the Rev. 
G. R. Leathes. 
SERPULA (SPIRORB1S?) granulate. 
TAB. DXCVII.— figs. 7. & 8. 
Spec. Char. Discoid, thick; surface granulated. 
A pretty Serpula, composed of little more than one 
whorl, ornamented by rows of very prominent granules : 
it is about two lines in diameter. 
Attached to a Terebratula in Chalk. Presented by the 
Rev. R. T. Lowe. 
Fig. 8. is a magnified representation.
