Figure 4. A view of the under surface of the gland and duct completely laid bare as far as the termination of 
the duct, at the root of the fang. The membrane which incloses the fang is also removed, to expose the sub¬ 
sidiary teeth ; these are only connected by soft parts, and are moved forwards into the socket to replace the fang 
when it has been pulled out. 
Figures 5, 6 , and 7, represent three views of the poison gland of the Katuka Rekula Poda. 
Figure 5. In this view the gland is scarcely seen, on account of a fascia which covers it. The muscle that 
acts upon this fascia, lies behind the angle of the lower jaw, and its tendon is distinctly seen connected with 
the fascia. 
Figure 6 . The gland and duct are completely exposed, putting on a very different appearance from that of 
the Cobra de Capello. 
Figure 7, represents a view of the subsidiary teeth, and their relative situation to the fangs and the mem¬ 
branes in which they are inclosed.
