450 GENLISEA ORNATA. Cuar. XVIII 
could be recognised. It is, indeed, scarcely possible 
that any object could enter the small orifice and pass 
down the long narrow neck, except. a living creature. 
Within the necks, however, of some specimens, a worm 
with retracted horny jaws, the abdomen of some 
articulate animal, and specks of dirt, probably the 
remnants of other minute creatures, were found. 
Many of the papille within both the utricles and 
necks were discoloured, as if they had absorbed matter. 
From this description it is sufficiently obvious how 
Genlisea secures its prey. Small animals entering 
the narrow orifice—but what induces them to enter is 
not known any more than in the case of Utricularia— 
would find their egress rendered difficult by the sharp 
incurved hairs on the lips, and as soon as they passed 
some way down the neck, it would be scarcely possible 
for them to return, owing to the many transverse rows 
of long, straight, downward pointing hairs, together 
with the ridges from which these project. Such crea- 
tures would, therefore, perish either within the neck 
or utricle; and the quadrifid and bifid papille would 
absorb matter from their decayed remains. The 
transverse rows of hairs are so numerous that they 
seem superfiuous merely for the sake of preventing 
the escape of prey, and as they are thin and delicate, 
they probably serve as additional absorbents, in the 
sume manner as the flexible bristles on the infolded 
margins of the leaves of Aldrovanda. The spiral arms 
no doubt act as accessory traps. Until fresh leaves 
are examined, it cannot be told whether the line of 
junction of the spirally wound lamina is a little open 
along its whole course, or only in parts, but a small 
creature which forced its way into the tube at any 
point, would be prevented from escaping by the 
incurved hairs, and would find an open path down
